[Portaudio] Portaudio Test fails on ARM

Hi,
On capturing strace for patest1 I get below output. Please let me know
which files it is looking for because libm.so.6 is present in /lib64 in my
board.
How do I solve below error when running ./patest1 on arm board:

*/usr/bin/aarch64-linux-gnu-gcc-5: line 1: ELF : not
found/usr/bin/aarch64-linux-gnu-gcc-5: line 2: syntax error: unexpected

Hi,
I have cross compiled portaudio (v190600_20161030) for ARM platform using
*./configure --host=aarch64-linux-gnu --build=x86_64-pc-linux-gnu
--prefix=/usr/local/portaudio
--with-alsa=/home/ap/Desktop/VVDN_AVS/alexa/local_build_arm/alsa-lib
--with-jack=no *
After doing make and make install I copied libportaudio.a &
libportaudio.so.2.0.0 on my board.
Also copied scripts & .lib folder under bin onto my board. Changed the
paths mentioned under *relink_command* as it was showing the path of host

Hello,

Which Gcc this is build on and is ARM binary? It seems that you have
build it diffrent GCC/Glibc and run on diffrent.

Hi,
I have cross compiled portaudio (v190600_20161030) for ARM
*./configure --host=aarch64-linux-gnu --build=x86_64-pc-linux-gnu
--prefix=/usr/local/portaudio
--with-alsa=/home/ap/Desktop/VVDN_AVS/alexa/local_build_arm/alsa-lib
--with-jack=no *
After doing make and make install I copied libportaudio.a &
libportaudio.so.2.0.0 on my board.
Also copied scripts & .lib folder under bin onto my board. Changed
the paths mentioned under *relink_command* as it was showing the
path of host system. Then I run ./patest1 on board and below error
*/usr/bin/aarch64-linux-gnu-gcc-5: line 1: ELF : not found
/usr/bin/aarch64-linux-gnu-gcc-5: line 2: syntax error: unexpected
"("n/data/alexa/portaudio*
aarch64-linux-gnu-ar
aarch64-linux-gnu-elfedit
aarch64-linux-gnu-g++-5
aarch64-linux-gnu-gcc-5
aarch64-linux-gnu-ld
aarch64-linux-gnu-ranlib
aarch64-linux-gnu-readelf
Please guide me to solve this problem.

Hi,
I have cross compiled port audio for ARM using tool chain
aarch64-linux-gnu-gcc-5.
patest1 binary created under bin/.libs is ARM compatible.
*file ./patest1*
patest1: ELF 64-bit LSB executable, ARM aarch64, version 1 (SYSV),
dynamically linked, interpreter /lib/ld-linux-aarch64.so.1, for GNU/Linux
3.7.0, BuildID[sha1]=41bcc7f37ae402143d94e31ce69e7e0147954dbd, not stripped

Can you please guide further?

Post by Tuukka Pasanen
Hello,
Which Gcc this is build on and is ARM binary? It seems that you have build
it diffrent GCC/Glibc and run on diffrent.
Tuukka
Hi,
On capturing strace for patest1 I get below output. Please let me know
which files it is looking for because libm.so.6 is present in /lib64 in my
board.

Hi,
I have cross compiled portaudio (v190600_20161030) for ARM platform using
*./configure --host=aarch64-linux-gnu --build=x86_64-pc-linux-gnu
--prefix=/usr/local/portaudio
--with-alsa=/home/ap/Desktop/VVDN_AVS/alexa/local_build_arm/alsa-lib
--with-jack=no *
After doing make and make install I copied libportaudio.a &
libportaudio.so.2.0.0 on my board.
Also copied scripts & .lib folder under bin onto my board. Changed the
paths mentioned under *relink_command* as it was showing the path of
*/usr/bin/aarch64-linux-gnu-gcc-5: line 1: ELF : not found
/usr/bin/aarch64-linux-gnu-gcc-5: line 2: syntax error: unexpected
"("n/data/alexa/portaudio*
aarch64-linux-gnu-ar
aarch64-linux-gnu-elfedit
aarch64-linux-gnu-g++-5
aarch64-linux-gnu-gcc-5
aarch64-linux-gnu-ld
aarch64-linux-gnu-ranlib
aarch64-linux-gnu-readelf
Please guide me to solve this problem.

Hello,

Ok it seems to be ARM binary and you have ARM64 SOC/ARM board. I just
noted (about your first email) that you have probably copied script
(which links to .libs) not executable? If it's executable and not script
then what does ldd say about so linked libraries.

I think easiest to over come this with autotools is make prefix
somewhere in your home dir and then 'make install' application (and then
copy these libs) or copy under .libs-directory binary executable.

Hi,
I have cross compiled port audio for ARM using tool chain
aarch64-linux-gnu-gcc-5.
patest1 binary created under bin/.libs is ARM compatible.
*file ./patest1*
patest1: ELF 64-bit LSB executable, ARM aarch64, version 1 (SYSV),
dynamically linked, interpreter /lib/ld-linux-aarch64.so.1, for
GNU/Linux 3.7.0,
BuildID[sha1]=41bcc7f37ae402143d94e31ce69e7e0147954dbd, not stripped
Can you please guide further?

Hello,
Which Gcc this is build on and is ARM binary? It seems that you
have build it diffrent GCC/Glibc and run on diffrent.

Hi,
On capturing strace for patest1 I get below output. Please let me
know which files it is looking for because libm.so.6 is present

Hi,
I have cross compiled portaudio (v190600_20161030) for ARM
*./configure --host=aarch64-linux-gnu
--build=x86_64-pc-linux-gnu --prefix=/usr/local/portaudio
--with-alsa=/home/ap/Desktop/VVDN_AVS/alexa/local_build_arm/alsa-lib
--with-jack=no *
After doing make and make install I copied libportaudio.a &
libportaudio.so.2.0.0 on my board.
Also copied scripts & .lib folder under bin onto my board.
Changed the paths mentioned under *relink_command* as it was
showing the path of host system. Then I run ./patest1 on
*/usr/bin/aarch64-linux-gnu-gcc-5: line 1: ELF : not found
unexpected "("n/data/alexa/portaudio*
aarch64-linux-gnu-ar
aarch64-linux-gnu-elfedit
aarch64-linux-gnu-g++-5
aarch64-linux-gnu-gcc-5
aarch64-linux-gnu-ld
aarch64-linux-gnu-ranlib
aarch64-linux-gnu-readelf
Please guide me to solve this problem.

Hi,

Post by Tuukka Pasanen
I think easiest to over come this with autotools is make prefix

somewhere in your home dir and then 'make install' application (and then
copy

these libs) or copy under .libs-directory binary executable.

Post by Tuukka Pasanen
Hello,
Ok it seems to be ARM binary and you have ARM64 SOC/ARM board. I just
noted (about your first email) that you have probably copied script (which
links to .libs) not executable? If it's executable and not script then what
does ldd say about so linked libraries.

Hi,
I have cross compiled port audio for ARM using tool chain
aarch64-linux-gnu-gcc-5.
patest1 binary created under bin/.libs is ARM compatible.
*file ./patest1*
patest1: ELF 64-bit LSB executable, ARM aarch64, version 1 (SYSV),
dynamically linked, interpreter /lib/ld-linux-aarch64.so.1, for GNU/Linux
3.7.0, BuildID[sha1]=41bcc7f37ae402143d94e31ce69e7e0147954dbd, not stripped
Can you please guide further?

Post by Tuukka Pasanen
Hello,
Which Gcc this is build on and is ARM binary? It seems that you have
build it diffrent GCC/Glibc and run on diffrent.

Hi,
I have cross compiled portaudio (v190600_20161030) for ARM platform
*./configure --host=aarch64-linux-gnu --build=x86_64-pc-linux-gnu
--prefix=/usr/local/portaudio
--with-alsa=/home/ap/Desktop/VVDN_AVS/alexa/local_build_arm/alsa-lib
--with-jack=no *
After doing make and make install I copied libportaudio.a &
libportaudio.so.2.0.0 on my board.
Also copied scripts & .lib folder under bin onto my board. Changed the
paths mentioned under *relink_command* as it was showing the path of
*/usr/bin/aarch64-linux-gnu-gcc-5: line 1: ELF : not found
/usr/bin/aarch64-linux-gnu-gcc-5: line 2: syntax error: unexpected
"("n/data/alexa/portaudio*
aarch64-linux-gnu-ar
aarch64-linux-gnu-elfedit
aarch64-linux-gnu-g++-5
aarch64-linux-gnu-gcc-5
aarch64-linux-gnu-ld
aarch64-linux-gnu-ranlib
aarch64-linux-gnu-readelf
Please guide me to solve this problem.

Hi,
From strace of patest1 binary I find *newfstatat(AT_FDCWD,
"/data/alexa/portaudio/.libs/**lt-patest1", 0x7fdb369aa0, 0) = -1 ENOENT
(No such file or directory)* error.
How do I find this file or generate by rebuilding portaudio? Because in the
build I prepared does not contain this file. Is this file really required
for patest1 to execute?

I think easiest to over come this with autotools is make prefix

somewhere in your home dir and then 'make install' application (and then
copy

Post by Tuukka Pasanen
these libs) or copy under .libs-directory binary executable.

Post by Tuukka Pasanen
Hello,
Which Gcc this is build on and is ARM binary? It seems that you have
build it diffrent GCC/Glibc and run on diffrent.

Hi,
On capturing strace for patest1 I get below output. Please let me know
which files it is looking for because libm.so.6 is present in /lib64 in my

Hello,

As it tries to point it's on cross-build machine
'/data/alexa/portaudio/.libs/lt-patest1'.

File which is named patest1 is just bash-script which makes sure that
when you run application on development it picks up shared object. You
can use cat|more|less to make sure that it's really just bash-script.

Hi,
From strace of patest1 binary I find *newfstatat(AT_FDCWD,
"/data/alexa/portaudio/.libs/**lt-patest1", 0x7fdb369aa0, 0) = -1
ENOENT (No such file or directory)* error.
How do I find this file or generate by rebuilding portaudio? Because
in the build I prepared does not contain this file. Is this file
really required for patest1 to execute?

Hi,

I think easiest to over come this with autotools is make prefix

somewhere in your home dir and then 'make install' application
(and then copy

these libs) or copy under .libs-directory binary executable.

I followed the same procedure. I copied script as well as .libs
from bin directory and .so library into standard path. In any case
it did not show the missing libraries error. The scripts present
is a wrapper for binary. Executing the *patest1* binary also
throws same error.
Can you please suggest how to debug more into this?

Hello,
Ok it seems to be ARM binary and you have ARM64 SOC/ARM board.
I just noted (about your first email) that you have probably
copied script (which links to .libs) not executable? If it's
executable and not script then what does ldd say about so
linked libraries.
I think easiest to over come this with autotools is make
prefix somewhere in your home dir and then 'make install'
application (and then copy these libs) or copy under

Hi,
I have cross compiled port audio for ARM using tool chain
aarch64-linux-gnu-gcc-5.
patest1 binary created under bin/.libs is ARM compatible.
*file ./patest1*
patest1: ELF 64-bit LSB executable, ARM aarch64, version 1
(SYSV), dynamically linked, interpreter
/lib/ld-linux-aarch64.so.1, for GNU/Linux 3.7.0,
BuildID[sha1]=41bcc7f37ae402143d94e31ce69e7e0147954dbd, not stripped
Can you please guide further?

Hello,
Which Gcc this is build on and is ARM binary? It seems
that you have build it diffrent GCC/Glibc and run on
diffrent.

Hi,
I have cross compiled portaudio (v190600_20161030)
*./configure --host=aarch64-linux-gnu
--build=x86_64-pc-linux-gnu
--prefix=/usr/local/portaudio
--with-alsa=/home/ap/Desktop/VVDN_AVS/alexa/local_build_arm/alsa-lib
--with-jack=no *
After doing make and make install I copied
libportaudio.a & libportaudio.so.2.0.0 on my board.
Also copied scripts & .lib folder under bin onto my
board. Changed the paths mentioned under
*relink_command* as it was showing the path of host
system. Then I run ./patest1 on board and below
*/usr/bin/aarch64-linux-gnu-gcc-5: line 1: ELF : not
found
/usr/bin/aarch64-linux-gnu-gcc-5: line 2: syntax

Please guide me to solve this problem.

Hi,

I am trying to play patest1 or patest_sine8 binary I get below error for
each:
1. *./patest1*
patest1.c
Ring modulate input for 20 seconds.
Error: No input default device.
bye

2. *./patest_sine8*
PortAudio Test: output signed 8 bit sine wave.
Error: No default output device.
An error occured while using the portaudio stream
Error number: 0
Error message: Success

I verified the speaker using aplay & tinyplay utility & I can hear sound.
What is missing with portaudio?
*ldd patest1*
linux-vdso.so.1 (0x0000007fb652c000)
libportaudio.so.2 => /usr/lib64/libportaudio.so.2 (0x0000007fb64c2000)
libm.so.6 => /lib64/libm.so.6 (0x0000007fb6420000)

Hello,
As it tries to point it's on cross-build machine
'/data/alexa/portaudio/.libs/lt-patest1'.
File which is named patest1 is just bash-script which makes sure that when
you run application on development it picks up shared object. You can use
cat|more|less to make sure that it's really just bash-script.
Tuukka
Hi,
From strace of patest1 binary I find *newfstatat(AT_FDCWD,
"/data/alexa/portaudio/.libs/**lt-patest1", 0x7fdb369aa0, 0) = -1 ENOENT
(No such file or directory)* error.
How do I find this file or generate by rebuilding portaudio? Because in
the build I prepared does not contain this file. Is this file really
required for patest1 to execute?

I think easiest to over come this with autotools is make prefix

somewhere in your home dir and then 'make install' application (and then
copy

these libs) or copy under .libs-directory binary executable.

Post by Tuukka Pasanen
Hello,
Ok it seems to be ARM binary and you have ARM64 SOC/ARM board. I just
noted (about your first email) that you have probably copied script (which
links to .libs) not executable? If it's executable and not script then what
does ldd say about so linked libraries.

Hi,
I have cross compiled port audio for ARM using tool chain
aarch64-linux-gnu-gcc-5.
patest1 binary created under bin/.libs is ARM compatible.
*file ./patest1*
patest1: ELF 64-bit LSB executable, ARM aarch64, version 1 (SYSV),
dynamically linked, interpreter /lib/ld-linux-aarch64.so.1, for GNU/Linux
3.7.0, BuildID[sha1]=41bcc7f37ae402143d94e31ce69e7e0147954dbd, not stripped
Can you please guide further?

Post by Tuukka Pasanen
Hello,
Which Gcc this is build on and is ARM binary? It seems that you have
build it diffrent GCC/Glibc and run on diffrent.

Hi,
On capturing strace for patest1 I get below output. Please let me know
which files it is looking for because libm.so.6 is present in /lib64 in my

Hi,

Using patest1 & patest_sine8, it shows *No input default device*. Also
using *pa_devs* it shows below output:
/data/alexa/portaudio/.libs # *./pa_devs*
PortAudio version: 0x00130600

396fe4b6699ae929d3a685b3ef8a7e97396139a4'
Number of devices = 0
----------------------------------------------

My audio board with inbuilt mic is connected still it shows this error.
What is missing with portaudio?

Hello,
As it tries to point it's on cross-build machine
'/data/alexa/portaudio/.libs/lt-patest1'.
File which is named patest1 is just bash-script which makes sure that
when you run application on development it picks up shared object. You can
use cat|more|less to make sure that it's really just bash-script.
Tuukka
Hi,
From strace of patest1 binary I find *newfstatat(AT_FDCWD,
"/data/alexa/portaudio/.libs/**lt-patest1", 0x7fdb369aa0, 0) = -1 ENOENT
(No such file or directory)* error.
How do I find this file or generate by rebuilding portaudio? Because in
the build I prepared does not contain this file. Is this file really
required for patest1 to execute?

I think easiest to over come this with autotools is make prefix

somewhere in your home dir and then 'make install' application (and then
copy

these libs) or copy under .libs-directory binary executable.

Hello,
Ok it seems to be ARM binary and you have ARM64 SOC/ARM board. I just
noted (about your first email) that you have probably copied script (which
links to .libs) not executable? If it's executable and not script then what
does ldd say about so linked libraries.

Hi,
I have cross compiled port audio for ARM using tool chain
aarch64-linux-gnu-gcc-5.
patest1 binary created under bin/.libs is ARM compatible.
*file ./patest1*
patest1: ELF 64-bit LSB executable, ARM aarch64, version 1 (SYSV),
dynamically linked, interpreter /lib/ld-linux-aarch64.so.1, for GNU/Linux
3.7.0, BuildID[sha1]=41bcc7f37ae402143d94e31ce69e7e0147954dbd, not stripped
Can you please guide further?

Post by Tuukka Pasanen
Hello,
Which Gcc this is build on and is ARM binary? It seems that you have
build it diffrent GCC/Glibc and run on diffrent.

Hi,
On capturing strace for patest1 I get below output. Please let me know
which files it is looking for because libm.so.6 is present in /lib64 in my

Hi,
I have cross compiled portaudio (v190600_20161030) for ARM platform
*./configure --host=aarch64-linux-gnu --build=x86_64-pc-linux-gnu
--prefix=/usr/local/portaudio
--with-alsa=/home/ap/Desktop/VVDN_AVS/alexa/local_build_arm/alsa-lib
--with-jack=no *
After doing make and make install I copied libportaudio.a &
libportaudio.so.2.0.0 on my board.
Also copied scripts & .lib folder under bin onto my board. Changed
the paths mentioned under *relink_command* as it was showing the
path of host system. Then I run ./patest1 on board and below error is

Hi,
From strace of patest1 binary I find *newfstatat(AT_FDCWD,
"/data/alexa/portaudio/.libs/**lt-patest1", 0x7fdb369aa0, 0)

How do I find this file or generate by rebuilding portaudio?
Because in the build I prepared does not contain this file.
Is this file really required for patest1 to execute?

Hi,

I think easiest to over come this with autotools is

make prefix somewhere in your home dir and then 'make
install' application (and then copy

these libs) or copy under .libs-directory binary

executable.
I followed the same procedure. I copied script as well as
.libs from bin directory and .so library into standard
path. In any case it did not show the missing libraries
error. The scripts present is a wrapper for binary.
Executing the *patest1* binary also throws same error.
Can you please suggest how to debug more into this?

Hello,
Ok it seems to be ARM binary and you have ARM64
SOC/ARM board. I just noted (about your first email)
that you have probably copied script (which links to
.libs) not executable? If it's executable and not
script then what does ldd say about so linked libraries.
I think easiest to over come this with autotools is
make prefix somewhere in your home dir and then 'make
install' application (and then copy these libs) or

Hi,
I have cross compiled port audio for ARM using tool
chain aarch64-linux-gnu-gcc-5.
patest1 binary created under bin/.libs is ARM
compatible.
*file ./patest1*
patest1: ELF 64-bit LSB executable, ARM aarch64,
version 1 (SYSV), dynamically linked, interpreter
/lib/ld-linux-aarch64.so.1, for GNU/Linux 3.7.0,
BuildID[sha1]=41bcc7f37ae402143d94e31ce69e7e0147954dbd,
not stripped
Can you please guide further?

Hello,
Which Gcc this is build on and is ARM binary? It
seems that you have build it diffrent GCC/Glibc
and run on diffrent.

Hi,
On capturing strace for patest1 I get below
output. Please let me know which files it is
looking for because libm.so.6 is present in
/lib64 in my board.
How do I solve below error when running

Hi,
I have cross compiled portaudio
(v190600_20161030) for ARM platform using
*./configure --host=aarch64-linux-gnu
--build=x86_64-pc-linux-gnu
--prefix=/usr/local/portaudio
--with-alsa=/home/ap/Desktop/VVDN_AVS/alexa/local_build_arm/alsa-lib
--with-jack=no *
After doing make and make install I copied
libportaudio.a & libportaudio.so.2.0.0 on
my board.
Also copied scripts & .lib folder under bin
onto my board. Changed the paths mentioned
under *relink_command* as it was showing
the path of host system. Then I run
ELF : not found
syntax error: unexpected
"("n/data/alexa/portaudio*
aarch64-linux-gnu-ar
aarch64-linux-gnu-elfedit
aarch64-linux-gnu-g++-5
aarch64-linux-gnu-gcc-5
aarch64-linux-gnu-ld
aarch64-linux-gnu-ranlib
aarch64-linux-gnu-readelf
Please guide me to solve this problem.

Hi,
Yes ALSA reports the devices. Executing cat /proc/asound/cards list the
devices.
Here is the output for reference:
*cat /proc/asound/cards*

Hello,
Does ALSA report any devices?

My audio board with inbuilt mic is connected still it shows this error.
What is missing with portaudio?

Hello,
As it tries to point it's on cross-build machine
'/data/alexa/portaudio/.libs/lt-patest1'.
File which is named patest1 is just bash-script which makes sure that
when you run application on development it picks up shared object. You can
use cat|more|less to make sure that it's really just bash-script.

Hi,
From strace of patest1 binary I find *newfstatat(AT_FDCWD,
"/data/alexa/portaudio/.libs/**lt-patest1", 0x7fdb369aa0, 0) = -1
ENOENT (No such file or directory)* error.
How do I find this file or generate by rebuilding portaudio? Because in
the build I prepared does not contain this file. Is this file really
required for patest1 to execute?

these libs) or copy under .libs-directory binary executable.

Hello,
Ok it seems to be ARM binary and you have ARM64 SOC/ARM board. I just
noted (about your first email) that you have probably copied script (which
links to .libs) not executable? If it's executable and not script then what
does ldd say about so linked libraries.

Hi,
I have cross compiled port audio for ARM using tool chain
aarch64-linux-gnu-gcc-5.
patest1 binary created under bin/.libs is ARM compatible.
*file ./patest1*
patest1: ELF 64-bit LSB executable, ARM aarch64, version 1 (SYSV),
dynamically linked, interpreter /lib/ld-linux-aarch64.so.1, for GNU/Linux
3.7.0, BuildID[sha1]=41bcc7f37ae402143d94e31ce69e7e0147954dbd, not stripped
Can you please guide further?

Hello,
Which Gcc this is build on and is ARM binary? It seems that you have
build it diffrent GCC/Glibc and run on diffrent.

Hi,
On capturing strace for patest1 I get below output. Please let me
know which files it is looking for because libm.so.6 is present in /lib64
in my board.

Hi,
I have cross compiled portaudio (v190600_20161030) for ARM platform
*./configure --host=aarch64-linux-gnu --build=x86_64-pc-linux-gnu
--prefix=/usr/local/portaudio
--with-alsa=/home/ap/Desktop/VVDN_AVS/alexa/local_build_arm/alsa-lib
--with-jack=no *
After doing make and make install I copied libportaudio.a &
libportaudio.so.2.0.0 on my board.
Also copied scripts & .lib folder under bin onto my board. Changed
the paths mentioned under *relink_command* as it was showing the
path of host system. Then I run ./patest1 on board and below error is
*/usr/bin/aarch64-linux-gnu-gcc-5: line 1: ELF : not found

Hi,

Attaching the strace for patest1 for reference. From the logs I can see
that it is looking for /dev/dsp entry which is not present. So what
modifications are expected?

Hi,
Yes ALSA reports the devices. Executing cat /proc/asound/cards list the
devices.

does ldd say about so linked libraries.
I think easiest to over come this with autotools is make prefix
somewhere in your home dir and then 'make install' application (and then
copy these libs) or copy under .libs-directory binary executable.

Hi,
I have cross compiled port audio for ARM using tool chain
aarch64-linux-gnu-gcc-5.
patest1 binary created under bin/.libs is ARM compatible.
*file ./patest1*
patest1: ELF 64-bit LSB executable, ARM aarch64, version 1 (SYSV),
dynamically linked, interpreter /lib/ld-linux-aarch64.so.1, for GNU/Linux
3.7.0, BuildID[sha1]=41bcc7f37ae402143d94e31ce69e7e0147954dbd, not stripped
Can you please guide further?

Hello,
Which Gcc this is build on and is ARM binary? It seems that you have
build it diffrent GCC/Glibc and run on diffrent.

Hi,
On capturing strace for patest1 I get below output. Please let me
know which files it is looking for because libm.so.6 is present in /lib64

Hi,
I have cross compiled portaudio (v190600_20161030) for ARM platform
*./configure --host=aarch64-linux-gnu --build=x86_64-pc-linux-gnu
--prefix=/usr/local/portaudio

After doing make and make install I copied libportaudio.a &
libportaudio.so.2.0.0 on my board.
Also copied scripts & .lib folder under bin onto my board. Changed
the paths mentioned under *relink_command* as it was showing the
path of host system. Then I run ./patest1 on board and below error is

Hello,

Disable OSS but it shouldn't behave like that.. You should little bit
examine source and documents as this is open source project and we are
volunteer people so mainly I can't walk you through every step of debugging.

Hi,
Attaching the strace for patest1 for reference. From the logs I can
see that it is looking for /dev/dsp entry which is not present. So
what modifications are expected?
Hi,
Yes ALSA reports the devices. Executing cat /proc/asound/cards
list the devices.

Hello,
As it tries to point it's on cross-build machine
'/data/alexa/portaudio/.libs/lt-patest1'.
File which is named patest1 is just bash-script which
makes sure that when you run application on
development it picks up shared object. You can use
cat|more|less to make sure that it's really just
bash-script.

Hi,
From strace of patest1 binary I find
*newfstatat(AT_FDCWD,
"/data/alexa/portaudio/.libs/**lt-patest1",
0x7fdb369aa0, 0) = -1 ENOENT (No such file or
directory)* error.
How do I find this file or generate by rebuilding
portaudio? Because in the build I prepared does not
contain this file. Is this file really required for
patest1 to execute?

Hi,

Post by Tuukka Pasanen
I think easiest to over come this with

autotools is make prefix somewhere in your home
dir and then 'make install' application (and
then copy

Post by Tuukka Pasanen
these libs) or copy under .libs-directory

binary executable.
I followed the same procedure. I copied script
as well as .libs from bin directory and .so
library into standard path. In any case it did
not show the missing libraries error. The
scripts present is a wrapper for binary.
Executing the *patest1* binary also throws same
error.
Can you please suggest how to debug more into this?

Ok it seems to be ARM binary and you have
ARM64 SOC/ARM board. I just noted (about
your first email) that you have probably
copied script (which links to .libs) not
executable? If it's executable and not
script then what does ldd say about so
linked libraries.
I think easiest to over come this with
autotools is make prefix somewhere in your
home dir and then 'make install' application
(and then copy these libs) or copy under
.libs-directory binary executable.

Hi,
I have cross compiled port audio for ARM
using tool chain aarch64-linux-gnu-gcc-5.
patest1 binary created under bin/.libs is
ARM compatible.
*file ./patest1*
patest1: ELF 64-bit LSB executable, ARM
aarch64, version 1 (SYSV), dynamically
linked, interpreter
/lib/ld-linux-aarch64.so.1, for GNU/Linux
3.7.0,
BuildID[sha1]=41bcc7f37ae402143d94e31ce69e7e0147954dbd,
not stripped
Can you please guide further?

Hello,
Which Gcc this is build on and is ARM
binary? It seems that you have build it
diffrent GCC/Glibc and run on diffrent.

Hi,
On capturing strace for patest1 I get
below output. Please let me know which
files it is looking for because
libm.so.6 is present in /lib64 in my
board.
How do I solve below error when

Hi,
I have cross compiled portaudio
(v190600_20161030) for ARM
*./configure
--host=aarch64-linux-gnu
--build=x86_64-pc-linux-gnu
--prefix=/usr/local/portaudio
--with-alsa=/home/ap/Desktop/VVDN_AVS/alexa/local_build_arm/alsa-lib
--with-jack=no *
After doing make and make install
I copied libportaudio.a &
libportaudio.so.2.0.0 on my board.
Also copied scripts & .lib folder
under bin onto my board. Changed
the paths mentioned under
*relink_command* as it was showing
the path of host system. Then I
run ./patest1 on board and below
line 1: ELF : not found
line 2: syntax error: unexpected
"("n/data/alexa/portaudio*
aarch64-linux-gnu-ar
aarch64-linux-gnu-elfedit
aarch64-linux-gnu-g++-5
aarch64-linux-gnu-gcc-5
aarch64-linux-gnu-ld
aarch64-linux-gnu-ranlib
aarch64-linux-gnu-readelf
Please guide me to solve this problem.

Hi,
Thanks for your support. Disabling OSS removed /the /dev/dsp entry.
Attached debugs for reference just to get in right direction.
Executing patest1 or patest_sine8 it gets me segmentation fault. Any
suggestions for what could be the reasons it is causing segmentation fault?
After segmentation fault, audio board does not play anything.
Just before segmentation fault error, I observe below debugs:

write(2, "FillInDevInfo: Adding device msm"..., 65FillInDevInfo: Adding
device msm8953-snd-card-mtp: - (hw:0,4): 4

Hello,
Disable OSS but it shouldn't behave like that.. You should little bit
examine source and documents as this is open source project and we are
volunteer people so mainly I can't walk you through every step of debugging.

Hi,
Attaching the strace for patest1 for reference. From the logs I can see
that it is looking for /dev/dsp entry which is not present. So what
modifications are expected?

Hi,
I am trying to play patest1 or patest_sine8 binary I get below error
1. *./patest1*
patest1.c
Ring modulate input for 20 seconds.
Error: No input default device.
bye
2. *./patest_sine8*
PortAudio Test: output signed 8 bit sine wave.
Error: No default output device.
An error occured while using the portaudio stream
Error number: 0
Error message: Success
I verified the speaker using aplay & tinyplay utility & I can hear
sound. What is missing with portaudio?
*ldd patest1*

Hello,
As it tries to point it's on cross-build machine
'/data/alexa/portaudio/.libs/lt-patest1'.
File which is named patest1 is just bash-script which makes sure that
when you run application on development it picks up shared object. You can
use cat|more|less to make sure that it's really just bash-script.
Tuukka
Hi,
From strace of patest1 binary I find *newfstatat(AT_FDCWD,
"/data/alexa/portaudio/.libs/**lt-patest1", 0x7fdb369aa0, 0) = -1
ENOENT (No such file or directory)* error.
How do I find this file or generate by rebuilding portaudio? Because
in the build I prepared does not contain this file. Is this file really
required for patest1 to execute?

I think easiest to over come this with autotools is make prefix

somewhere in your home dir and then 'make install' application (and then
copy

these libs) or copy under .libs-directory binary executable.

Post by Tuukka Pasanen
Hello,
Ok it seems to be ARM binary and you have ARM64 SOC/ARM board. I
just noted (about your first email) that you have probably copied script
(which links to .libs) not executable? If it's executable and not script
then what does ldd say about so linked libraries.

Hi,
I have cross compiled port audio for ARM using tool chain
aarch64-linux-gnu-gcc-5.
patest1 binary created under bin/.libs is ARM compatible.
*file ./patest1*
patest1: ELF 64-bit LSB executable, ARM aarch64, version 1 (SYSV),
dynamically linked, interpreter /lib/ld-linux-aarch64.so.1, for GNU/Linux
3.7.0, BuildID[sha1]=41bcc7f37ae402143d94e31ce69e7e0147954dbd, not stripped
Can you please guide further?

Hello,
Which Gcc this is build on and is ARM binary? It seems that you
have build it diffrent GCC/Glibc and run on diffrent.

Hi,
I have cross compiled portaudio (v190600_20161030) for ARM
*./configure --host=aarch64-linux-gnu --build=x86_64-pc-linux-gnu
--prefix=/usr/local/portaudio
--with-alsa=/home/ap/Desktop/VVDN_AVS/alexa/local_build_arm/alsa-lib
--with-jack=no *
After doing make and make install I copied libportaudio.a &
libportaudio.so.2.0.0 on my board.
Also copied scripts & .lib folder under bin onto my board. Changed
the paths mentioned under *relink_command* as it was showing the
path of host system. Then I run ./patest1 on board and below error is
*/usr/bin/aarch64-linux-gnu-gcc-5: line 1: ELF : not found

Hello,

Can you compile with debug symbols on and attach remote/local gdb to it
and backtrace? After that we can see where it really crashes. There is
some ALSA problem in parsing card entry.

Your audio card is some USB, on board or bluetooth mobile MTP? Do you
have correct group info for you i.e you belong audio group (probably
because you get ALSA info for msm8953). Does aplay for example (if you
have it in your system) or it this android board?

Probably it crashes ALSA pipes or messes up setting up configuration
when it SIGSEGV.

Hi,
Thanks for your support. Disabling OSS removed /the /dev/dsp entry.
Attached debugs for reference just to get in right direction.
Executing patest1 or patest_sine8 it gets me segmentation fault. Any
suggestions for what could be the reasons it is causing segmentation
fault? After segmentation fault, audio board does not play anything.

Hello,
Disable OSS but it shouldn't behave like that.. You should little
bit examine source and documents as this is open source project
and we are volunteer people so mainly I can't walk you through
every step of debugging.

Hi,
Attaching the strace for patest1 for reference. From the logs I
can see that it is looking for /dev/dsp entry which is not
present. So what modifications are expected?

Hi,
Yes ALSA reports the devices. Executing cat
/proc/asound/cards list the devices.

Hi,
Using patest1 & patest_sine8, it shows *No input default

Hello,
As it tries to point it's on cross-build machine
'/data/alexa/portaudio/.libs/lt-patest1'.
File which is named patest1 is just bash-script
which makes sure that when you run application
on development it picks up shared object. You
can use cat|more|less to make sure that it's
really just bash-script.

Hi,
From strace of patest1 binary I find
*newfstatat(AT_FDCWD,
"/data/alexa/portaudio/.libs/**lt-patest1",
0x7fdb369aa0, 0) = -1 ENOENT (No such file or
directory)* error.
How do I find this file or generate by
rebuilding portaudio? Because in the build I
prepared does not contain this file. Is this
file really required for patest1 to execute?

Hi,

Post by Tuukka Pasanen
I think easiest to over come this with

autotools is make prefix somewhere in your
home dir and then 'make install'
application (and then copy

Post by Tuukka Pasanen
these libs) or copy under

.libs-directory binary executable.
I followed the same procedure. I copied
script as well as .libs from bin directory
and .so library into standard path. In any
case it did not show the missing libraries
error. The scripts present is a wrapper for
binary. Executing the *patest1* binary also
throws same error.
Can you please suggest how to debug more
into this?

Hello,
Ok it seems to be ARM binary and you
have ARM64 SOC/ARM board. I just noted
(about your first email) that you have
probably copied script (which links to
.libs) not executable? If it's
executable and not script then what
does ldd say about so linked libraries.

Hi,
I have cross compiled port audio for
ARM using tool chain
aarch64-linux-gnu-gcc-5.
patest1 binary created under bin/.libs
is ARM compatible.
*file ./patest1*
patest1: ELF 64-bit LSB executable,
ARM aarch64, version 1 (SYSV),
dynamically linked, interpreter
/lib/ld-linux-aarch64.so.1, for
GNU/Linux 3.7.0,

Can you please guide further?

Hello,
Which Gcc this is build on and is
ARM binary? It seems that you have
build it diffrent GCC/Glibc and
run on diffrent.

Hi,
I have cross compiled
portaudio (v190600_20161030)
for ARM platform using below
*./configure
--host=aarch64-linux-gnu
--build=x86_64-pc-linux-gnu
--prefix=/usr/local/portaudio
--with-alsa=/home/ap/Desktop/VVDN_AVS/alexa/local_build_arm/alsa-lib
--with-jack=no *
After doing make and make
install I copied
libportaudio.a &
libportaudio.so.2.0.0 on my
board.
Also copied scripts & .lib
folder under bin onto my
board. Changed the paths
mentioned under
*relink_command* as it was
showing the path of host
system. Then I run ./patest1
on board and below error is
line 1: ELF : not found
unexpected
"("n/data/alexa/portaudio*
aarch64-linux-gnu-ar
aarch64-linux-gnu-elfedit
aarch64-linux-gnu-g++-5
aarch64-linux-gnu-gcc-5
aarch64-linux-gnu-ld
aarch64-linux-gnu-ranlib
aarch64-linux-gnu-readelf
Please guide me to solve this
problem.

Hi,
On compiling with debug symbols and running gdb on board but backtrace
shows 'no stack'. Attaching the gdb debug for reference
(gdb_patest_sine8.txt). I found that in file "*pa_linux_alsa.c*" it gets
stuck in function FillInDevInfo. Just an observation, if i run patest_sine8
for first time then it shows '*Filling device info for*' debug hw:0,0 to
hw:0,5 and executing patest_sine8 again it stops at *FillInDevInfo: Filling
device info for: msm8953-snd-card-mtp: - (hw:0,0)*. After this I cannot
access the terminal. It gets freeze.

My audio card is on board connected through spi/i2s. My board (APQ8009 SOC
for reference) is running linux and have aplay inbuilt.
As you doubt that there is ALSA problem in parsing card entry, so is some
configuration required to be done in alsa.conf or any other alsa specific
files?

Post by Tuukka Pasanen
Hello,
Can you compile with debug symbols on and attach remote/local gdb to it
and backtrace? After that we can see where it really crashes. There is some
ALSA problem in parsing card entry.
Your audio card is some USB, on board or bluetooth mobile MTP? Do you have
correct group info for you i.e you belong audio group (probably because you
get ALSA info for msm8953). Does aplay for example (if you have it in your
system) or it this android board?
Probably it crashes ALSA pipes or messes up setting up configuration when
it SIGSEGV.
Tuukka
Hi,
Thanks for your support. Disabling OSS removed /the /dev/dsp entry.
Attached debugs for reference just to get in right direction.
Executing patest1 or patest_sine8 it gets me segmentation fault. Any
suggestions for what could be the reasons it is causing segmentation fault?
After segmentation fault, audio board does not play anything.

Hello,
As it tries to point it's on cross-build machine
'/data/alexa/portaudio/.libs/lt-patest1'.
File which is named patest1 is just bash-script which makes sure that
when you run application on development it picks up shared object. You can
use cat|more|less to make sure that it's really just bash-script.
Tuukka
Hi,
From strace of patest1 binary I find *newfstatat(AT_FDCWD,
"/data/alexa/portaudio/.libs/**lt-patest1", 0x7fdb369aa0, 0) = -1
ENOENT (No such file or directory)* error.
How do I find this file or generate by rebuilding portaudio? Because
in the build I prepared does not contain this file. Is this file really
required for patest1 to execute?

I think easiest to over come this with autotools is make prefix

somewhere in your home dir and then 'make install' application (and then
copy

these libs) or copy under .libs-directory binary executable.

Post by Tuukka Pasanen
Hello,
Ok it seems to be ARM binary and you have ARM64 SOC/ARM board. I
just noted (about your first email) that you have probably copied script
(which links to .libs) not executable? If it's executable and not script
then what does ldd say about so linked libraries.

Hi,
I have cross compiled port audio for ARM using tool chain
aarch64-linux-gnu-gcc-5.
patest1 binary created under bin/.libs is ARM compatible.
*file ./patest1*
patest1: ELF 64-bit LSB executable, ARM aarch64, version 1 (SYSV),
dynamically linked, interpreter /lib/ld-linux-aarch64.so.1, for GNU/Linux
3.7.0, BuildID[sha1]=41bcc7f37ae402143d94e31ce69e7e0147954dbd, not stripped
Can you please guide further?

Hello,
Which Gcc this is build on and is ARM binary? It seems that you
have build it diffrent GCC/Glibc and run on diffrent.

Hi,
On capturing strace for patest1 I get below output. Please let me

Hi,
I have cross compiled portaudio (v190600_20161030) for ARM
*./configure --host=aarch64-linux-gnu --build=x86_64-pc-linux-gnu
--prefix=/usr/local/portaudio
--with-alsa=/home/ap/Desktop/VVDN_AVS/alexa/local_build_arm/alsa-lib
--with-jack=no *
After doing make and make install I copied libportaudio.a &
libportaudio.so.2.0.0 on my board.
Also copied scripts & .lib folder under bin onto my board.
Changed the paths mentioned under *relink_command* as it was
showing the path of host system. Then I run ./patest1 on board and below
*/usr/bin/aarch64-linux-gnu-gcc-5: line 1: ELF : not found
/usr/bin/aarch64-linux-gnu-gcc-5: line 2: syntax error: unexpected

Hello,

Crash happens in function (As you may allready noticed):

https://app.assembla.com/spaces/portaudio/git/source/master/src/hostapi/alsa/pa_linux_alsa.c#ln1149

So as it seems to crash very very harsh as there is no gdb stack or it's
some weird ARM binary which doesn't produce stack. So you have to debug
by adding PA_DEBUG prints and see what is the last place where it prints
and crashes. This sounds memory corruption but I can see how.

Post by Arjav Parikh
Hi,
On compiling with debug symbols and running gdb on board but backtrace
shows 'no stack'. Attaching the gdb debug for reference
(gdb_patest_sine8.txt). I found that in file "*pa_linux_alsa.c*" it
gets stuck in function FillInDevInfo. Just an observation, if i run
patest_sine8 for first time then it shows '*Filling device info for*'
debug hw:0,0 to hw:0,5 and executing patest_sine8 again it stops at
*FillInDevInfo: Filling device info for: msm8953-snd-card-mtp: -
(hw:0,0)*. After this I cannot access the terminal. It gets freeze.
My audio card is on board connected through spi/i2s. My board (APQ8009
SOC for reference) is running linux and have aplay inbuilt.
As you doubt that there is ALSA problem in parsing card entry, so is
some configuration required to be done in alsa.conf or any other alsa
specific files?
On Tue, Oct 23, 2018 at 12:20 PM Tuukka Pasanen
Hello,
Can you compile with debug symbols on and attach remote/local gdb
to it and backtrace? After that we can see where it really
crashes. There is some ALSA problem in parsing card entry.
Your audio card is some USB, on board or bluetooth mobile MTP? Do
you have correct group info for you i.e you belong audio group
(probably because you get ALSA info for msm8953). Does aplay for
example (if you have it in your system) or it this android board?
Probably it crashes ALSA pipes or messes up setting up
configuration when it SIGSEGV.

Hi,
Thanks for your support. Disabling OSS removed /the /dev/dsp
entry. Attached debugs for reference just to get in right direction.
Executing patest1 or patest_sine8 it gets me segmentation fault.
Any suggestions for what could be the reasons it is causing
segmentation fault? After segmentation fault, audio board does
not play anything.

Hello,
Disable OSS but it shouldn't behave like that.. You should
little bit examine source and documents as this is open
source project and we are volunteer people so mainly I can't
walk you through every step of debugging.

Hi,
Attaching the strace for patest1 for reference. From the
logs I can see that it is looking for /dev/dsp entry which
is not present. So what modifications are expected?

Yes ALSA reports the devices. Executing cat

Hello,
As it tries to point it's on cross-build
machine
'/data/alexa/portaudio/.libs/lt-patest1'.
File which is named patest1 is just
bash-script which makes sure that when you
run application on development it picks up
shared object. You can use cat|more|less to
make sure that it's really just bash-script.
Tuukka

Post by Arjav Parikh
Hi,
From strace of patest1 binary I find
*newfstatat(AT_FDCWD,
"/data/alexa/portaudio/.libs/**lt-patest1",
0x7fdb369aa0, 0) = -1 ENOENT (No such file
or directory)* error.
How do I find this file or generate by
rebuilding portaudio? Because in the build
I prepared does not contain this file. Is
this file really required for patest1 to
execute?

Hi,

Post by Tuukka Pasanen
I think easiest to over come this

with autotools is make prefix
somewhere in your home dir and then
'make install' application (and then copy

Post by Tuukka Pasanen
these libs) or copy under

.libs-directory binary executable.
I followed the same procedure. I
copied script as well as .libs from
bin directory and .so library into
standard path. In any case it did not
show the missing libraries error. The
scripts present is a wrapper for
binary. Executing the *patest1* binary
also throws same error.
Can you please suggest how to debug
more into this?

Hello,
Ok it seems to be ARM binary and
you have ARM64 SOC/ARM board. I
just noted (about your first
email) that you have probably
copied script (which links to
.libs) not executable? If it's
executable and not script then
what does ldd say about so linked
libraries.

Hi,
I have cross compiled
portaudio
(v190600_20161030) for
ARM platform using below
*./configure
--host=aarch64-linux-gnu
--build=x86_64-pc-linux-gnu
--prefix=/usr/local/portaudio
--with-alsa=/home/ap/Desktop/VVDN_AVS/alexa/local_build_arm/alsa-lib
--with-jack=no *
After doing make and
make install I copied
libportaudio.a &
libportaudio.so.2.0.0 on
my board.
Also copied scripts &
.lib folder under bin
onto my board. Changed
the paths mentioned
under *relink_command*
as it was showing the
path of host system.
Then I run ./patest1 on
board and below error is
line 1: ELF : not found
unexpected
"("n/data/alexa/portaudio*
aarch64-linux-gnu-ar
aarch64-linux-gnu-elfedit
aarch64-linux-gnu-g++-5
aarch64-linux-gnu-gcc-5
aarch64-linux-gnu-ld
aarch64-linux-gnu-ranlib
aarch64-linux-gnu-readelf
Please guide me to solve
this problem.

Hello,
is your board provided audio line in?

Post by Tuukka Pasanen
Hello,
https://app.assembla.com/spaces/portaudio/git/source/master/src/hostapi/alsa/pa_linux_alsa.c#ln1149
So as it seems to crash very very harsh as there is no gdb stack or it's
some weird ARM binary which doesn't produce stack. So you have to debug by
adding PA_DEBUG prints and see what is the last place where it prints and
crashes. This sounds memory corruption but I can see how.
Tuukka
Hi,
On compiling with debug symbols and running gdb on board but backtrace
shows 'no stack'. Attaching the gdb debug for reference
(gdb_patest_sine8.txt). I found that in file "*pa_linux_alsa.c*" it gets
stuck in function FillInDevInfo. Just an observation, if i run patest_sine8
for first time then it shows '*Filling device info for*' debug hw:0,0 to
Filling device info for: msm8953-snd-card-mtp: - (hw:0,0)*. After this I
cannot access the terminal. It gets freeze.
My audio card is on board connected through spi/i2s. My board (APQ8009 SOC
for reference) is running linux and have aplay inbuilt.
As you doubt that there is ALSA problem in parsing card entry, so is some
configuration required to be done in alsa.conf or any other alsa specific
files?

Post by Tuukka Pasanen
Hello,
Can you compile with debug symbols on and attach remote/local gdb to it
and backtrace? After that we can see where it really crashes. There is some
ALSA problem in parsing card entry.
Your audio card is some USB, on board or bluetooth mobile MTP? Do you
have correct group info for you i.e you belong audio group (probably
because you get ALSA info for msm8953). Does aplay for example (if you have
it in your system) or it this android board?
Probably it crashes ALSA pipes or messes up setting up configuration when
it SIGSEGV.
Tuukka
Hi,
Thanks for your support. Disabling OSS removed /the /dev/dsp entry.
Attached debugs for reference just to get in right direction.
Executing patest1 or patest_sine8 it gets me segmentation fault. Any
suggestions for what could be the reasons it is causing segmentation fault?
After segmentation fault, audio board does not play anything.

Hello,
Does ALSA report any devices?

Hi,
Using patest1 & patest_sine8, it shows *No input default device*.

My audio board with inbuilt mic is connected still it shows this
error. What is missing with portaudio?

Thanks & Regards,

Post by Tuukka Pasanen
Hello,
As it tries to point it's on cross-build machine
'/data/alexa/portaudio/.libs/lt-patest1'.
File which is named patest1 is just bash-script which makes sure
that when you run application on development it picks up shared object. You
can use cat|more|less to make sure that it's really just bash-script.
Tuukka
Hi,
From strace of patest1 binary I find *newfstatat(AT_FDCWD,
"/data/alexa/portaudio/.libs/**lt-patest1", 0x7fdb369aa0, 0) = -1
ENOENT (No such file or directory)* error.
How do I find this file or generate by rebuilding portaudio? Because
in the build I prepared does not contain this file. Is this file really
required for patest1 to execute?

I think easiest to over come this with autotools is make prefix

somewhere in your home dir and then 'make install' application (and then
copy

these libs) or copy under .libs-directory binary executable.

Post by Tuukka Pasanen
Hello,
Ok it seems to be ARM binary and you have ARM64 SOC/ARM board. I
just noted (about your first email) that you have probably copied script
(which links to .libs) not executable? If it's executable and not script
then what does ldd say about so linked libraries.

Hi,
I have cross compiled port audio for ARM using tool chain
aarch64-linux-gnu-gcc-5.
patest1 binary created under bin/.libs is ARM compatible.

Hello,
Which Gcc this is build on and is ARM binary? It seems that you
have build it diffrent GCC/Glibc and run on diffrent.

Hi,
I have cross compiled portaudio (v190600_20161030) for ARM
*./configure --host=aarch64-linux-gnu
--build=x86_64-pc-linux-gnu --prefix=/usr/local/portaudio
--with-alsa=/home/ap/Desktop/VVDN_AVS/alexa/local_build_arm/alsa-lib
--with-jack=no *
After doing make and make install I copied libportaudio.a &
libportaudio.so.2.0.0 on my board.
Also copied scripts & .lib folder under bin onto my board.
Changed the paths mentioned under *relink_command* as it was
showing the path of host system. Then I run ./patest1 on board and below
*/usr/bin/aarch64-linux-gnu-gcc-5: line 1: ELF : not found

Hi,
I added debugs in pa_linux_alsa.c file and found that before getting
segmentation fault "*alsa_snd_pcm_open*" under OpenPcm function is the last
function called and gets crashed. I am attaching the debug for reference (
*patest_sine8_crash_debug.tx*t).
Is there some issue with alsa library or some conf file related to alsa
need to be set? I am using alsa-lib-1.1.6.

Yes the board is provided audio in.

Post by Tuukka Pasanen
Hello,
is your board provided audio line in?

Post by Tuukka Pasanen
Hello,
https://app.assembla.com/spaces/portaudio/git/source/master/src/hostapi/alsa/pa_linux_alsa.c#ln1149
So as it seems to crash very very harsh as there is no gdb stack or it's
some weird ARM binary which doesn't produce stack. So you have to debug by
adding PA_DEBUG prints and see what is the last place where it prints and
crashes. This sounds memory corruption but I can see how.
Tuukka
Hi,
On compiling with debug symbols and running gdb on board but backtrace
shows 'no stack'. Attaching the gdb debug for reference
(gdb_patest_sine8.txt). I found that in file "*pa_linux_alsa.c*" it gets
stuck in function FillInDevInfo. Just an observation, if i run patest_sine8
for first time then it shows '*Filling device info for*' debug hw:0,0 to
Filling device info for: msm8953-snd-card-mtp: - (hw:0,0)*. After this I
cannot access the terminal. It gets freeze.
My audio card is on board connected through spi/i2s. My board (APQ8009
SOC for reference) is running linux and have aplay inbuilt.
As you doubt that there is ALSA problem in parsing card entry, so is some
configuration required to be done in alsa.conf or any other alsa specific
files?

Post by Tuukka Pasanen
Hello,
Can you compile with debug symbols on and attach remote/local gdb to it
and backtrace? After that we can see where it really crashes. There is some
ALSA problem in parsing card entry.
Your audio card is some USB, on board or bluetooth mobile MTP? Do you
have correct group info for you i.e you belong audio group (probably
because you get ALSA info for msm8953). Does aplay for example (if you have
it in your system) or it this android board?
Probably it crashes ALSA pipes or messes up setting up configuration
when it SIGSEGV.
Tuukka
Hi,
Thanks for your support. Disabling OSS removed /the /dev/dsp entry.
Attached debugs for reference just to get in right direction.
Executing patest1 or patest_sine8 it gets me segmentation fault. Any
suggestions for what could be the reasons it is causing segmentation fault?
After segmentation fault, audio board does not play anything.

Hello,
As it tries to point it's on cross-build machine
'/data/alexa/portaudio/.libs/lt-patest1'.
File which is named patest1 is just bash-script which makes sure
that when you run application on development it picks up shared object. You
can use cat|more|less to make sure that it's really just bash-script.
Tuukka
Hi,
From strace of patest1 binary I find *newfstatat(AT_FDCWD,
"/data/alexa/portaudio/.libs/**lt-patest1", 0x7fdb369aa0, 0) = -1
ENOENT (No such file or directory)* error.
How do I find this file or generate by rebuilding portaudio?
Because in the build I prepared does not contain this file. Is this file
really required for patest1 to execute?

I think easiest to over come this with autotools is make prefix

Post by Tuukka Pasanen
Hello,
Ok it seems to be ARM binary and you have ARM64 SOC/ARM board. I
just noted (about your first email) that you have probably copied script
(which links to .libs) not executable? If it's executable and not script
then what does ldd say about so linked libraries.

Hi,
I have cross compiled portaudio (v190600_20161030) for ARM
*./configure --host=aarch64-linux-gnu
--build=x86_64-pc-linux-gnu --prefix=/usr/local/portaudio
--with-alsa=/home/ap/Desktop/VVDN_AVS/alexa/local_build_arm/alsa-lib
--with-jack=no *
After doing make and make install I copied libportaudio.a &
libportaudio.so.2.0.0 on my board.
Also copied scripts & .lib folder under bin onto my board.
Changed the paths mentioned under *relink_command* as it was
showing the path of host system. Then I run ./patest1 on board and below
*/usr/bin/aarch64-linux-gnu-gcc-5: line 1: ELF : not found
/usr/bin/aarch64-linux-gnu-gcc-5: line 2: syntax error: unexpected
"("n/data/alexa/portaudio*
aarch64-linux-gnu-ar
aarch64-linux-gnu-elfedit
aarch64-linux-gnu-g++-5
aarch64-linux-gnu-gcc-5
aarch64-linux-gnu-ld
aarch64-linux-gnu-ranlib
aarch64-linux-gnu-readelf
Please guide me to solve this problem.

Hello,

I cannot comment on the details of your cross compilation. But I will just
make a couple quick suggestions.

Please see the instructions for cross compiling for Beagle Board. There may
be some clues there.

https://app.assembla.com/wiki/show/portaudio/Platforms_BeagleBoard

I recommend using static linking with PortAudio library instead of shared
libraries.
I think --disable-shared will do that.

Also try to verify ALSA installation using aplay or other ALSA program
before using PortAudio.

And if you finally find out the secret to making this work, then please let
us know and we can update the Wiki for PortAudio.

Also, thanks Tukka and others for being so helpful.

Hi,
I tried using static library instead of shared library and also referred
the steps mentioned for cross compilation but still the same segmentation
fault is observed.
Also verified ALSA by playing a wav file using aplay before using
PortAudio. It is working.

Thank you Phil and Tukka for your support.

Ok you need to add openPCM debugs also so we see what's crashing. I'm
having my doubts but have be sure.

Hi,
After adding debugs in OpenPCM function it is observed that below for loop
is not executed because maxTries value remains 0:
ret = alsa_snd_pcm_open( pcmp, name, stream, mode );
PA_DEBUG(( "%s: ret before loop is : %d\n", __FUNCTION__, ret));

for( tries = 0; tries < maxTries && -EBUSY == ret; ++tries )
{
Pa_Sleep( 10 );
PA_DEBUG(( "%s: Loop name:%s, ptr: %p, stream:%d, mode:%d,
waitonBusy:%d, maxTries:%d, tries:%d \n",
__FUNCTION__,name,*pcmp,stream,mode,waitOnBusy,maxTries, tries));
ret = alsa_snd_pcm_open( pcmp, name, stream, mode );
PA_DEBUG(( "ret is :%d \n", ret));
if( -EBUSY != ret )
{
PA_DEBUG(( "%s: Successfully opened initially busy device after
%d tries\n", __FUNCTION__, tries ));
}
}

Attached debug file for reference (*patest_sine8_crash_debug_2.txt*).
Kindly let me know in case of any additional information required from my
end.

Hello,

Hmm... If I understand correct your ALSA is hw:0,2 and hw:0,4. Second
opening crashes everything. Does aplay -l also report this as two
separated devices?

Hello,
Hmm... If I understand correct your ALSA is hw:0,2 and hw:0,4. Second
opening crashes everything. Does aplay -l also report this as two separated
devices?

Hi,
After adding debugs in OpenPCM function it is observed that below for loop
ret = alsa_snd_pcm_open( pcmp, name, stream, mode );
PA_DEBUG(( "%s: ret before loop is : %d\n", __FUNCTION__, ret));
for( tries = 0; tries < maxTries && -EBUSY == ret; ++tries )
{
Pa_Sleep( 10 );
PA_DEBUG(( "%s: Loop name:%s, ptr: %p, stream:%d, mode:%d,

ret = alsa_snd_pcm_open( pcmp, name, stream, mode );
PA_DEBUG(( "ret is :%d \n", ret));
if( -EBUSY != ret )
{
PA_DEBUG(( "%s: Successfully opened initially busy device
after %d tries\n", __FUNCTION__, tries ));
}
}
Attached debug file for reference (*patest_sine8_crash_debug_2.txt*).
Kindly let me know in case of any additional information required from my

Hello,
I cannot comment on the details of your cross compilation. But I will
just make a couple quick suggestions.
Please see the instructions for cross compiling for Beagle Board. There
may be some clues there.
https://app.assembla.com/wiki/show/portaudio/Platforms_BeagleBoard
I recommend using static linking with PortAudio library instead of
shared libraries.
I think --disable-shared will do that.
Also try to verify ALSA installation using aplay or other ALSA program
before using PortAudio.
And if you finally find out the secret to making this work, then please
let us know and we can update the Wiki for PortAudio.
Also, thanks Tukka and others for being so helpful.

Hello,

Sorry it was aplay -L not -l. If crashes on hw:0,4 same as portaudio
then it works same as portaudio if not then we can look code how it
doesn't. There is huge amount of outputs in that card.

Ok you need to add openPCM debugs also so we see what's
crashing. I'm having my doubts but have be sure.

Hi,
I tried using static library instead of shared library and
also referred the steps mentioned for cross compilation but
still the same segmentation fault is observed.
Also verified ALSA by playing a wav file using aplay before
using PortAudio. It is working.
Thank you Phil and Tukka for your support.

Hi,
Actually aplay -L also doesn't work. It shows same output as invalid
option. As aplay is being used for embedded software so maybe it is having
limited options.
How do I confirm that it crashes only on hw0,4? From aplay -V debug it
shows only subdevice 0.

Is it possible to check Portuadio on ARM platform for anyone because the
same code works on X86? As it is a audio sound card from ZL38063 so it is
showing huge amount of outputs.

PA_DEBUG(( "%s: ret before loop is : %d\n", __FUNCTION__, ret));
for( tries = 0; tries < maxTries && -EBUSY == ret; ++tries )
{
Pa_Sleep( 10 );
PA_DEBUG(( "%s: Loop name:%s, ptr: %p, stream:%d, mode:%d,
waitonBusy:%d, maxTries:%d, tries:%d \n",
__FUNCTION__,name,*pcmp,stream,mode,waitOnBusy,maxTries, tries));
ret = alsa_snd_pcm_open( pcmp, name, stream, mode );
PA_DEBUG(( "ret is :%d \n", ret));
if( -EBUSY != ret )
{
PA_DEBUG(( "%s: Successfully opened initially busy device
after %d tries\n", __FUNCTION__, tries ));
}
}
Attached debug file for reference (*patest_sine8_crash_debug_2.txt*).
Kindly let me know in case of any additional information required from my
end.

Hello,
I cannot comment on the details of your cross compilation. But I will
just make a couple quick suggestions.
Please see the instructions for cross compiling for Beagle Board. There
may be some clues there.
https://app.assembla.com/wiki/show/portaudio/Platforms_BeagleBoard
I recommend using static linking with PortAudio library instead of
shared libraries.
I think --disable-shared will do that.
Also try to verify ALSA installation using aplay or other ALSA program
before using PortAudio.
And if you finally find out the secret to making this work, then please
let us know and we can update the Wiki for PortAudio.
Also, thanks Tukka and others for being so helpful.

Is it possible to check Portuadio on ARM platform for anyone because the same code works on X86? As it is a audio
sound card from ZL38063 so it is showing huge amount of outputs.

I don't know if this info can be of any help to you, but in the past I
wrote a small demonstration program for the Raspberry Pi 3B, under
Raspbian, that used Portaudio to playback a WAV file. It worked without
problems. The GUI was written in Free Pascal using Lazarus, and the
processing code, Portaudio interfacing included, in straight C code. The
application was firstly developed and debugged under Kubuntu on an Intel
platform, then the source code was transferred to the Raspberry and
recompiled there, without any problems.

Hello,

What does aplay -D hw:0,4

if it doesn't do anything what does aplay -D hw:0,4

I have to look what does aplay do otherwise. Are they both compiled with
same

Ok you should but some wav after that it tries to play something. You
can also test with hw:0,5 or make script loop and test until it doesn't
work or crash until hw:0,somethig. If it works with aplay then there is
some problem in portaudio.

Hi,
As per your suggestion I tried aplay -D with multiple hw:0,.... options and
below are the observations:
aplay -D hw:0,0 /data/Haze.wav - File gets played and can hear sound on
speaker.
aplay -D hw:0,1 /data/Haze.wav - aplay -D hw:0,4 /data/Haze.wav - File does
not get played and observe below output.
aplay -D hw:0,5 /data/Haze.wav - *Segmentation fault*

"If it works with aplay then there is some problem in portaudio." - Does
the about output confirms that problem is with alsa-lib?

aplay -D hw:0,1 /data/Haze.wav - aplay -D hw:0,4 /data/Haze.wav Output :

Hello,

Yes this more ALSA and kernel than Portaudio problem. If l read list
correctly 0,4 is ULL (what ever that is?) and 0,5 should be Primary
MI2S_RX Hostless (I2S Host?).

It would help to ask from ALSA IRC or mailing list why they crash and if
there is nothing to do (as they are reported automatically and can't be
probed to be crashing) then I think you need to make .alsarc but have no
idea which kind to prevent their appearance or use Pulseaudio/JACK if
possible.

Sincerely,

Tuukka

Hi,
As per your suggestion I tried aplay -D with multiple hw:0,....
aplay -D hw:0,0 /data/Haze.wav - File gets played and can hear sound
on speaker.
aplay -D hw:0,1 /data/Haze.wav - aplay -D hw:0,4 /data/Haze.wav - File
does not get played and observe below output.
aplay -D hw:0,5 /data/Haze.wav - *Segmentation fault*
"If it works with aplay then there is some problem in portaudio." -
Does the about output confirms that problem is with alsa-lib?

I don't know if this info can be of any help to you, but
in the past I wrote a small demonstration program for
the Raspberry Pi 3B, under Raspbian, that used Portaudio
to playback a WAV file. It worked without problems. The
GUI was written in Free Pascal using Lazarus, and the
processing code, Portaudio interfacing included, in
straight C code. The application was firstly developed
and debugged under Kubuntu on an Intel platform, then
the source code was transferred to the Raspberry and
recompiled there, without any problems.

Hi,
As aplay works (I mean sound is heard) only on hw:0,0 and as cat
/proc/asound/pcm shows 0,0 with playback & capture interface then is it
possible in portaudio to fill device info only for hw:0,0 (i.e 1 device
which is working) instead of all 47 devices? Also in crash debugs we can
see that there is no address for hw:0,4 & hw:0,5.

Is it possible to check Portuadio on ARM platform for anyone because
the same code works on X86? As it is a audio sound card from ZL38063 so it
is showing huge amount of outputs.
I don't know if this info can be of any help to you, but in the past I
wrote a small demonstration program for the Raspberry Pi 3B, under
Raspbian, that used Portaudio to playback a WAV file. It worked without

I don't know if this info can be of any help to
you, but in the past I wrote a small demonstration
program for the Raspberry Pi 3B, under Raspbian,
that used Portaudio to playback a WAV file. It
worked without problems. The GUI was written in
Free Pascal using Lazarus, and the processing code,
Portaudio interfacing included, in straight C code.
The application was firstly developed and debugged
under Kubuntu on an Intel platform, then the source
code was transferred to the Raspberry and
recompiled there, without any problems.

Hi,

I could not find the patch mentioned in the SVN. Raised the query on Alsa
MailList as well but no response from them. As per your another suggestion
I am trying to create alsarc file.

Post by Tuukka Pasanen
Hello,
Did this one solved? Portaudio tries to find every ALSA devices which is
most of times what people want.
Tuukka
Hi,
As aplay works (I mean sound is heard) only on hw:0,0 and as cat
/proc/asound/pcm shows 0,0 with playback & capture interface then is it
possible in portaudio to fill device info only for hw:0,0 (i.e 1 device
which is working) instead of all 47 devices? Also in crash debugs we can
see that there is no address for hw:0,4 & hw:0,5.

Hello,
Ok you should but some wav after that it tries to play something. You
can also test with hw:0,5 or make script loop and test until it doesn't
work or crash until hw:0,somethig. If it works with aplay then there is
some problem in portaudio.
Tuukka
Hi,
*aplay -D hw:0,4* do not output anything. This command as well as *aplay
-D hw:0,0 *does not show any output.
Yes aplay and other components are compiled in same environment. This is

Is it possible to check Portuadio on ARM platform for anyone because
the same code works on X86? As it is a audio sound card from ZL38063 so it
is showing huge amount of outputs.

Hi,

I created /etc/asound.conf and ~/.asoundrc with below contents but still
observe the Segmentation Fault. I think if somehow we restrict Portaudio to
fetch details of only hw:0,0 then may be this Segmentation Fault Issue
could be resolved.

Hi,

I made below modifications in *src/hostapi/alsa/pa_linux_alsa.c* function
*BuildDeviceList* to limit the *numDeviceNames = 1 *& commenting* assert
operation.*
*numDeviceNames = 1; //patch*
for( i = 0, devIdx = 0; i < numDeviceNames; ++i )
{
}
*//assert( devIdx < numDeviceNames ); //patch*
/* Now inspect 'dmix' and 'default' plugins */

After adding above 2 patches I can hear sound by running patest_sine8 but
get crash dump after sometime. Also error is observed in patest1.
What other modifications to make it success for numDeviceNames = 1?
Attaching the debug for patest_sine8, patest1 & pa_devs for reference (
*patest_sine8_core_dump.txt*).

Hello,
Yes this more ALSA and kernel than Portaudio problem. If l read list
correctly 0,4 is ULL (what ever that is?) and 0,5 should be Primary MI2S_RX
Hostless (I2S Host?).
It would help to ask from ALSA IRC or mailing list why they crash and
if there is nothing to do (as they are reported automatically and can't be
probed to be crashing) then I think you need to make .alsarc but have no
idea which kind to prevent their appearance or use Pulseaudio/JACK if
possible.
Sincerely,
Tuukka
Hi,
As per your suggestion I tried aplay -D with multiple hw:0,.... options
aplay -D hw:0,0 /data/Haze.wav - File gets played and can hear sound on
speaker.
aplay -D hw:0,1 /data/Haze.wav - aplay -D hw:0,4 /data/Haze.wav - File
does not get played and observe below output.
aplay -D hw:0,5 /data/Haze.wav - *Segmentation fault*
"If it works with aplay then there is some problem in portaudio." -
Does the about output confirms that problem is with alsa-lib?

Is it possible to check Portuadio on ARM platform for anyone because
the same code works on X86? As it is a audio sound card from ZL38063 so it
is showing huge amount of outputs.
I don't know if this info can be of any help to you, but in the past
I wrote a small demonstration program for the Raspberry Pi 3B, under
Raspbian, that used Portaudio to playback a WAV file. It worked without
problems. The GUI was written in Free Pascal using Lazarus, and the
processing code, Portaudio interfacing included, in straight C code. The
application was firstly developed and debugged under Kubuntu on an Intel
platform, then the source code was transferred to the Raspberry and
recompiled there, without any problems.

Hello,

Can you check if it crashes with aplay (if you play something that is
longer)? Which kernel do you use?

Tuukka

Post by Arjav Parikh
Hi,
I made below modifications in *src/hostapi/alsa/pa_linux_alsa.c*
function *BuildDeviceList* to limit the *numDeviceNames = 1 *&
commenting*assert operation.*
*numDeviceNames = 1; //patch*
for( i = 0, devIdx = 0; i < numDeviceNames; ++i )
Â Â Â {
Â Â Â }
*//assert( devIdx < numDeviceNames ); //patch*
Â Â Â /* Now inspect 'dmix' and 'default' plugins */
After adding above 2 patches I can hear sound by running patest_sine8
but get crash dump after sometime. Also error is observed in patest1.
What other modifications to make it success for numDeviceNames = 1?
Attaching the debug for patest_sine8, patest1 & pa_devs for reference
(*patest_sine8_core_dump.txt*).
Hi,
I created /etc/asound.conf and ~/.asoundrc with below contents but
still observe the Segmentation Fault. I think if somehow we
restrict Portaudio to fetch details of only hw:0,0 then may be
this Segmentation Fault Issue could be resolved.
pcm.!default {
Â Â Â Â Â Â Â type hw
Â Â Â Â Â Â Â card 0
Â Â Â Â Â Â Â device 0

ctl.!default {

Hi,
As aplay works (I mean sound is heard) only on hw:0,0 and
as cat /proc/asound/pcm shows 0,0 with playback & capture
interface then is it possible in portaudio to fill device
info only for hw:0,0 (i.e 1 device which is working)
instead of all 47 devices? Also in crash debugs we can
see that there is no address for hw:0,4 & hw:0,5. *

Hello,
Yes this more ALSA and kernel than Portaudio problem.
If l read list correctly 0,4 is ULL (what ever that
is?) and 0,5 should be Primary MI2S_RX Hostless (I2S
Host?).
It would help to ask from ALSA IRC or mailing list
why they crash and if there is nothing to do (as they
are reported automatically and can't be probed to be
crashing) then I think you need to make .alsarc but
have no idea which kind to prevent their appearance
or use Pulseaudio/JACK if possible.

Hello,
Ok you should but some wav after that it tries
to play something. You can also test with hw:0,5
or make script loop and test until it doesn't
work or crash until hw:0,somethig. If it works
with aplay then there is some problem in portaudio.

Hello,
Ok you should but some wav after that it tries to play something. You
can also test with hw:0,5 or make script loop and test until it doesn't
work or crash until hw:0,somethig. If it works with aplay then there is
some problem in portaudio.
Tuukka
Hi,
*aplay -D hw:0,4* do not output anything. This command as well as *aplay
-D hw:0,0 *does not show any output.
Yes aplay and other components are compiled in same environment. This
is yocto project.

Is it possible to check Portuadio on ARM platform for anyone
because the same code works on X86? As it is a audio sound card from
ZL38063 so it is showing huge amount of outputs.
I don't know if this info can be of any help to you, but in the
past I wrote a small demonstration program for the Raspberry Pi 3B, under
Raspbian, that used Portaudio to playback a WAV file. It worked without
problems. The GUI was written in Free Pascal using Lazarus, and the
processing code, Portaudio interfacing included, in straight C code. The
application was firstly developed and debugged under Kubuntu on an Intel
platform, then the source code was transferred to the Raspberry and
recompiled there, without any problems.

Hello,

Can't say with that debug information as can't see where it crashes and
why it stops. If I have to make guess it's something to do with threads
and implementation that in your ARM board.

You can try other example with no callback and does it also crash.

Hi,
I verified playing 30 sec long file and did not observe any crash
whereas patest_sine8 plays file for approx duration of 4 sec and then
it crashes.
Can you guide why patest1 also throws error.

Hi,
I made below modifications in *src/hostapi/alsa/pa_linux_alsa.c*
function *BuildDeviceList* to limit the *numDeviceNames = 1 *&
commenting*assert operation.*
*numDeviceNames = 1; //patch*
for( i = 0, devIdx = 0; i < numDeviceNames; ++i )
Â Â Â {
Â Â Â }
*//assert( devIdx < numDeviceNames ); //patch*
Â Â Â /* Now inspect 'dmix' and 'default' plugins */
After adding above 2 patches I can hear sound by running
patest_sine8 but get crash dump after sometime. Also error is
observed in patest1.
What other modifications to make it success for numDeviceNames = 1?
Attaching the debug for patest_sine8, patest1 & pa_devs for

Hi,
I created /etc/asound.conf and ~/.asoundrc with below

somehow we restrict Portaudio to fetch details of only hw:0,0
then may be this Segmentation Fault Issue could be resolved.

Hi,
As aplay works (I mean sound is heard) only on
hw:0,0 and as cat /proc/asound/pcm shows 0,0 with
playback & capture interface then is it possible in
portaudio to fill device info only for hw:0,0 (i.e 1
device which is working) instead of all 47 devices?
Also in crash debugs we can see that there is no
address for hw:0,4 & hw:0,5. *

Hello,
Yes this more ALSA and kernel than Portaudio
problem. If l read list correctly 0,4 is ULL
(what ever that is?) and 0,5 should be Primary
MI2S_RX Hostless (I2S Host?).
It would help to ask from ALSA IRC or mailing
list why they crash and if there is nothing to
do (as they are reported automatically and can't
be probed to be crashing) then I think you need
to make .alsarc but have no idea which kind to
prevent their appearance or use Pulseaudio/JACK
if possible.
Sincerely,
Tuukka

Hi,

On running gdb for patest_sine8, I get below information:

*Program received signal SIGABRT, Aborted.[Switching to LWP
3630]0x0000007f902b2d10 in raise () from /lib64/libc.so.6(gdb) backtrace#0

Is it something related to libc library used in my ARM board? In case of
patest1, I see errors like below. Am I missing something?

Hello,
Yes this more ALSA and kernel than Portaudio problem. If l read list
correctly 0,4 is ULL (what ever that is?) and 0,5 should be Primary MI2S_RX
Hostless (I2S Host?).
It would help to ask from ALSA IRC or mailing list why they crash and
if there is nothing to do (as they are reported automatically and can't be
probed to be crashing) then I think you need to make .alsarc but have no
idea which kind to prevent their appearance or use Pulseaudio/JACK if
possible.
Sincerely,
Tuukka
Hi,
As per your suggestion I tried aplay -D with multiple hw:0,....
aplay -D hw:0,0 /data/Haze.wav - File gets played and can hear sound
on speaker.
aplay -D hw:0,1 /data/Haze.wav - aplay -D hw:0,4 /data/Haze.wav -
File does not get played and observe below output.
aplay -D hw:0,5 /data/Haze.wav - *Segmentation fault*
"If it works with aplay then there is some problem in portaudio." -
Does the about output confirms that problem is with alsa-lib?

Hello,
Ok you should but some wav after that it tries to play something.
You can also test with hw:0,5 or make script loop and test until it doesn't
work or crash until hw:0,somethig. If it works with aplay then there is
some problem in portaudio.
Tuukka
Hi,
*aplay -D hw:0,4* do not output anything. This command as well as *aplay
-D hw:0,0 *does not show any output.
Yes aplay and other components are compiled in same environment.

Is it possible to check Portuadio on ARM platform for anyone
because the same code works on X86? As it is a audio sound card from
ZL38063 so it is showing huge amount of outputs.
I don't know if this info can be of any help to you, but in the
past I wrote a small demonstration program for the Raspberry Pi 3B, under
Raspbian, that used Portaudio to playback a WAV file. It worked without
problems. The GUI was written in Free Pascal using Lazarus, and the
processing code, Portaudio interfacing included, in straight C code. The
application was firstly developed and debugged under Kubuntu on an Intel
platform, then the source code was transferred to the Raspberry and
recompiled there, without any problems.

Hello,

If I can understand this correctly it crashes when it tries to wake up
thread thread after that . Ok you use older gcc also and glibc?

You don't happen to have valgrind to test with because it's more for
situations like this.

Hello,
Can't say with that debug information as can't see where it
crashes and why it stops. If I have to make guess it's something
to do with threads and implementation that in your ARM board.
You can try other example with no callback and does it also crash.

Hi,
I verified playing 30 sec long file and did not observe any crash
whereas patest_sine8 plays file for approx duration of 4 sec and
then it crashes.
Can you guide why patest1 also throws error.

Hello,
Can you check if it crashes with aplay (if you play something

Hi,
I made below modifications in
*src/hostapi/alsa/pa_linux_alsa.c* function
*BuildDeviceList* to limit the *numDeviceNames = 1 *&
commenting*assert operation.*
*numDeviceNames = 1; //patch*
for( i = 0, devIdx = 0; i < numDeviceNames; ++i )
Â Â Â {
Â Â Â }
*//assert( devIdx < numDeviceNames ); //patch*
Â Â Â /* Now inspect 'dmix' and 'default' plugins */
After adding above 2 patches I can hear sound by running
patest_sine8 but get crash dump after sometime. Also error
is observed in patest1.
What other modifications to make it success for
numDeviceNames = 1?
Attaching the debug for patest_sine8, patest1 & pa_devs for

Hi,
I created /etc/asound.conf and ~/.asoundrc with below

think if somehow we restrict Portaudio to fetch details

could be resolved.

Post by Arjav Parikh
Hi,
As aplay works (I mean sound is heard) only on
hw:0,0 and as cat /proc/asound/pcm shows 0,0
with playback & capture interface then is it
possible in portaudio to fill device info only
for hw:0,0 (i.e 1 device which is working)
instead of all 47 devices? Also in crash debugs
we can see that there is no address for hw:0,4
& hw:0,5. *

I don't know if this info
can be of any help to you,
but in the past I wrote a
small demonstration program
for the Raspberry Pi 3B,
under Raspbian, that used
Portaudio to playback a WAV
file. It worked without
problems. The GUI was
written in Free Pascal using
Lazarus, and the processing
code, Portaudio interfacing
included, in straight C
code. The application was
firstly developed and
debugged under Kubuntu on an
Intel platform, then the
source code was transferred
to the Raspberry and
recompiled there, without
any problems.

Hi,

gcc version is 4.9.3-r0 & glibc is 2.22-r0.
I will check for valgrind support for my build.

Post by Tuukka Pasanen
Hello,
If I can understand this correctly it crashes when it tries to wake up
thread thread after that . Ok you use older gcc also and glibc?
You don't happen to have valgrind to test with because it's more for
situations like this.

Hi,
*Program received signal SIGABRT, Aborted. [Switching to LWP 3630]
0x0000007f902b2d10 in raise () from /lib64/libc.so.6 (gdb) backtrace #0

Is it something related to libc library used in my ARM board? In case of
patest1, I see errors like below. Am I missing something?

Post by Tuukka Pasanen
Hello,
Can you check if it crashes with aplay (if you play something that is
longer)? Which kernel do you use?
Tuukka
Hi,
I made below modifications in *src/hostapi/alsa/pa_linux_alsa.c*
function *BuildDeviceList* to limit the *numDeviceNames = 1 *&
commenting* assert operation.*
*numDeviceNames = 1; //patch*
for( i = 0, devIdx = 0; i < numDeviceNames; ++i )
{
}
*//assert( devIdx < numDeviceNames ); //patch*
/* Now inspect 'dmix' and 'default' plugins */
After adding above 2 patches I can hear sound by running patest_sine8
but get crash dump after sometime. Also error is observed in patest1.
What other modifications to make it success for numDeviceNames = 1?
Attaching the debug for patest_sine8, patest1 & pa_devs for reference (
*patest_sine8_core_dump.txt*).

Hi,
I created /etc/asound.conf and ~/.asoundrc with below contents but
still observe the Segmentation Fault. I think if somehow we restrict
Portaudio to fetch details of only hw:0,0 then may be this Segmentation
Fault Issue could be resolved.

Hi,
I could not find the patch mentioned in the SVN. Raised the query on

Hello,
Did this one solved? Portaudio tries to find every ALSA devices which
is most of times what people want.
Tuukka
Hi,
As aplay works (I mean sound is heard) only on hw:0,0 and as cat
/proc/asound/pcm shows 0,0 with playback & capture interface then is it
possible in portaudio to fill device info only for hw:0,0 (i.e 1 device
which is working) instead of all 47 devices? Also in crash debugs we can
see that there is no address for hw:0,4 & hw:0,5.

Hello,
Yes this more ALSA and kernel than Portaudio problem. If l read list
correctly 0,4 is ULL (what ever that is?) and 0,5 should be Primary MI2S_RX
Hostless (I2S Host?).
It would help to ask from ALSA IRC or mailing list why they crash
and if there is nothing to do (as they are reported automatically and can't
be probed to be crashing) then I think you need to make .alsarc but have no
idea which kind to prevent their appearance or use Pulseaudio/JACK if
possible.
Sincerely,
Tuukka
Hi,
As per your suggestion I tried aplay -D with multiple hw:0,....

aplay -D hw:0,1 /data/Haze.wav - aplay -D hw:0,4 /data/Haze.wav -
File does not get played and observe below output.
aplay -D hw:0,5 /data/Haze.wav - *Segmentation fault*

Hello,
Ok you should but some wav after that it tries to play something.
You can also test with hw:0,5 or make script loop and test until it doesn't
work or crash until hw:0,somethig. If it works with aplay then there is
some problem in portaudio.

Hi,
*aplay -D hw:0,4* do not output anything. This command as well as *aplay

Is it possible to check Portuadio on ARM platform for anyone
because the same code works on X86? As it is a audio sound card from
ZL38063 so it is showing huge amount of outputs.
I don't know if this info can be of any help to you, but in the
past I wrote a small demonstration program for the Raspberry Pi 3B, under
Raspbian, that used Portaudio to playback a WAV file. It worked without
problems. The GUI was written in Free Pascal using Lazarus, and the

Hi,

I used valgrind for patest_sine8 & patest1 binary. I see error related to
ld-2.22.so. Attached debugs for your reference.
Does Portaudio have any dependency on glibc version?

Post by Arjav Parikh
Hi,
gcc version is 4.9.3-r0 & glibc is 2.22-r0.
I will check for valgrind support for my build.

Post by Tuukka Pasanen
Hello,
Can't say with that debug information as can't see where it crashes and
why it stops. If I have to make guess it's something to do with threads and
implementation that in your ARM board.
You can try other example with no callback and does it also crash.
Tuukka
Hi,
I verified playing 30 sec long file and did not observe any crash
whereas patest_sine8 plays file for approx duration of 4 sec and then it
crashes.
Can you guide why patest1 also throws error.

Is it possible to check Portuadio on ARM platform for anyone
because the same code works on X86? As it is a audio sound card from
ZL38063 so it is showing huge amount of outputs.
I don't know if this info can be of any help to you, but in the
past I wrote a small demonstration program for the Raspberry Pi 3B, under
Raspbian, that used Portaudio to playback a WAV file. It worked without
problems. The GUI was written in Free Pascal using Lazarus, and the
processing code, Portaudio interfacing included, in straight C code. The
application was firstly developed and debugged under Kubuntu on an Intel
platform, then the source code was transferred to the Raspberry and
recompiled there, without any problems.

Hi,

I get similar logs as shared previously related to uninitialized value
stuff in *aplay -D hw:0,5 /data/Haze.wav* (This command used to throw
Segmentation Fault *valgrind_aplay_seg_fault.txt*) as well as *aplay -D
hw:0,0 /data/Haze.wav* (Working condition *valgrind_aplay_working.txt*) .
Attaching the debug for reference.
Also, the error observed on executing patest1 got resolved by providing the
properties related to MIC using tinymix utility.
Alsa build version and runtime version is 1.1.0

@Tuukka: I would like to thank you for the support provided due to which I
could get Alexa running on my board.

Which makes me little bit nervous as it sounds there is heavy leak
somewhere or it's just valgrind noise. Does valgrind aplay -L (list
devices) or playing with device that doesn't work produce same stuff in
valgrind.
Just trying to find if this is Kernel, ALSA or Portaudio stuff. Your
kernel is also little old but I assume you can't do nothing about it and it
shouldn't be issue. You can't test this I2CS with something like RasPi 3
(Rasbian) and see if it behaves same.
What is version of ALSA?
Tuukka
Hi,
I used valgrind for patest_sine8 & patest1 binary. I see error related to
ld-2.22.so. Attached debugs for your reference.
Does Portaudio have any dependency on glibc version?

Post by Arjav Parikh
Hi,
gcc version is 4.9.3-r0 & glibc is 2.22-r0.
I will check for valgrind support for my build.

Post by Tuukka Pasanen
Hello,
Can't say with that debug information as can't see where it crashes and
why it stops. If I have to make guess it's something to do with threads and
implementation that in your ARM board.
You can try other example with no callback and does it also crash.
Tuukka
Hi,
I verified playing 30 sec long file and did not observe any crash
whereas patest_sine8 plays file for approx duration of 4 sec and then it
crashes.
Can you guide why patest1 also throws error.

Post by Tuukka Pasanen
Hello,
Can you check if it crashes with aplay (if you play something that is
longer)? Which kernel do you use?
Tuukka
Hi,
I made below modifications in *src/hostapi/alsa/pa_linux_alsa.c*
function *BuildDeviceList* to limit the *numDeviceNames = 1 *&
commenting* assert operation.*
*numDeviceNames = 1; //patch*
for( i = 0, devIdx = 0; i < numDeviceNames; ++i )
{
}
*//assert( devIdx < numDeviceNames ); //patch*
/* Now inspect 'dmix' and 'default' plugins */
After adding above 2 patches I can hear sound by running patest_sine8
but get crash dump after sometime. Also error is observed in patest1.
What other modifications to make it success for numDeviceNames = 1?
Attaching the debug for patest_sine8, patest1 & pa_devs for reference (
*patest_sine8_core_dump.txt*).

Post by Arjav Parikh
Hi,
I created /etc/asound.conf and ~/.asoundrc with below contents but
still observe the Segmentation Fault. I think if somehow we restrict
Portaudio to fetch details of only hw:0,0 then may be this Segmentation
Fault Issue could be resolved.
pcm.!default {
type hw
card 0
device 0
}
ctl.!default {
type hw
card 0
device 0
}

Post by Arjav Parikh
Hi,
I could not find the patch mentioned in the SVN. Raised the query on
Alsa MailList as well but no response from them. As per your another
suggestion I am trying to create alsarc file.

Post by Tuukka Pasanen
Hello,
Did this one solved? Portaudio tries to find every ALSA devices
which is most of times what people want.
Tuukka
Hi,
As aplay works (I mean sound is heard) only on hw:0,0 and as cat
/proc/asound/pcm shows 0,0 with playback & capture interface then is it
possible in portaudio to fill device info only for hw:0,0 (i.e 1 device
which is working) instead of all 47 devices? Also in crash debugs we can
see that there is no address for hw:0,4 & hw:0,5.

Hello,
Yes this more ALSA and kernel than Portaudio problem. If l read
list correctly 0,4 is ULL (what ever that is?) and 0,5 should be Primary
MI2S_RX Hostless (I2S Host?).
It would help to ask from ALSA IRC or mailing list why they crash
and if there is nothing to do (as they are reported automatically and can't
be probed to be crashing) then I think you need to make .alsarc but have no
idea which kind to prevent their appearance or use Pulseaudio/JACK if
possible.
Sincerely,
Tuukka
Hi,
As per your suggestion I tried aplay -D with multiple hw:0,....
aplay -D hw:0,0 /data/Haze.wav - File gets played and can hear
sound on speaker.
aplay -D hw:0,1 /data/Haze.wav - aplay -D hw:0,4 /data/Haze.wav -
File does not get played and observe below output.
aplay -D hw:0,5 /data/Haze.wav - *Segmentation fault*
"If it works with aplay then there is some problem in portaudio."
- Does the about output confirms that problem is with alsa-lib?

Hello,
Ok you should but some wav after that it tries to play something.
You can also test with hw:0,5 or make script loop and test until it doesn't
work or crash until hw:0,somethig. If it works with aplay then there is
some problem in portaudio.
Tuukka
Hi,
*aplay -D hw:0,4* do not output anything. This command as well
as *aplay -D hw:0,0 *does not show any output.
Yes aplay and other components are compiled in same environment.
This is yocto project.
