Try to run snd_info & snd_test for each sound device (they should be in pjsip-apps/bin/samples directory), just to make sure whether the existing pjmedia sound device abstraction (pasound.c in this case) can works on your board. If it is not working, then you may need to follow the quoted doc above, creating your own sound device wrapper. Here is the doc of sound device interface (sound.h): http://www.pjsip.org/pjmedia/docs/html/group__PJMED__SND.htm There are some samples of sound device wrapper implementation: pasound.c, symbian_sound[_aps].c, dsound.c Btw, since PJSIP sound device implementation on Linux is using PortAudio, it may also be useful to find related topics from PortAudio forums/mailing list archive.
