Hi,

I am trying to run Pjsua application on ARM and Linux but everytime I
execute the binary, I get the following error:

14:34:20.090    pjsua_aud.c  ..Error retrieving default audio device
parameters: Unable to find default audio device (PJMEDIA_EAUD_NODEFDEV)
[status=420006]

The application is able to get the driver count but is unable to find a
sound/audio device.

Can someone help and point what the problem could be and how can I rectify.

Thanks,
Tanvi

Hi,

I tried to look into the logs and get to know that it shows that number of
sound devices is 0.
However, I can see the sound device on the machine.

Regards,
Tanvi

Some other application has taken control of your sound devices.
Try closing those application (even media player) and restart PJSUA.

Are you operating with Pulseaudio ?
If you are operating with pulseaudio, then you should be able to use
"pulse" or "default" sound card. If you are operating barely on top of
ALSA, then you might have to make sure that only one application is
accessing the sound card.

Thanks all for the help but I the issue is that I do have a sound card
installed and it is not being used by any other application but still pjsua
gives the error.
Also, through the logs I can see that it is not able to get the sound
device.

Make sure you have the ALSA (asound) development files on your system.
On Ubuntu the package is 'libasound2-dev'. Check if this file exists
on your system '/usr/include/alsa/pcm.h'.
If it doesn't you'll need it at least while compiling pjproject.
