pjsip new-call error ... Unable to find default audio device (PJMEDIA_EAUD_NODEFDEV)

I get this error when I try to establish a new call from pjsip:

pjsua_aud.c ..Error retrieving default audio device parameters: Unable to find default audio device (PJMEDIA_EAUD_NODEFDEV) [status=420006] Exception: Object: {Account <sip:192.168.0.2:54496>}, operation=make_call(), error=Unable to find default audio device (PJMEDIA_EAUD_NODEFDEV)

I installed libasound2-dev: sudo apt-get install libasound2-dev, and recompiled pjsip, but still, it gives me the same result .. Am I missing something here?

N.B. I use Ubuntu 11.10 and the sound works fine with no problems, so please don't tell me I have problems in the sound card


Update

I configured and compiled the pjsip like this:

$ ./configure

$ make && make install

And like this:

$ ./configure --enable-shared --disable-static --enable-memalign-hack

$ make && make install

And also like this:

$ ./configure

$ make dep && make clean && make

And all ways gave me the same results.


Update 2

I made sure that all of below are installed, and still the problem persists:

sudo apt-get install portaudio19-dev libportaudio2 pulseaudio alsa-utils liboss4-salsa-dev alsa-base alsa-tools libasound2-plugins libasound2 libasound2-dev binutils binutils-dev libasound-dev pulseaudio-dev


Update 3

I ran it like below, and it worked:

pjproject-2.1.0/pjsip-apps/bin/pjsua-i686-pc-linux-gnu --capture-dev=-1 --playback-dev=-1

It can call the other party. But when I run it from a python script it gives me an error, even when I set the sound device like this:

lib.init(log_cfg = pj.LogConfig(level=LOG_LEVEL, callback=log_cb))
snd_dev = lib.get_snd_dev()
print snd_dev ## returns (-1,-2)
lib.set_snd_dev(0,0)

Error is:

12:39:55.753 os_core_unix.c !pjlib 2.1 for POSIX initialized 12:39:55.754 sip_endpoint.c .Creating endpoint instance... 12:39:55.754 pjlib .select() I/O Queue created (0x93f1a80) 12:39:55.754 sip_endpoint.c .Module "mod-msg-print" registered 12:39:55.754 sip_transport. .Transport manager created. 12:39:55.754 pjsua_core.c .PJSUA state changed: NULL --> CREATED 12:39:55.769

But weirdly worked, when I replaced the lib.set_snd_dev(0,0) with this line lib.set_null_snd_dev(), but of course the sound is not working, as I'm setting the sound device to null !!!

This happens when the development packages are not installed. From your error message i can tell that libasound-development-package is not installed. Do as following:

sudo apt-get install libasound2-dev

Pay attention that pjsip would still fail to set the default audio device since you have done the make as this package was missing. So you need to build Pjsip once again

at pjsip directory do the following respectively :

./configure
make dep 
make clean
make
make install

that'd do it.
