Regarding the same issue I've tried to update alsa driver but it doesn't works well (ref. http://ubuntuforums.org/showthread.php?t=556217 ). Nanang,I have to use Alsa and not OSS (dev/dsp id=12) for other kind of reasons. So,When I launch pjsua with ./pjsua-i686-pc-linux-gnu --config-file=pjsuaConfig, by selecting the audio device 0 (I post my SNDINFO at the end of this message), I Obtain the following output. Why all of this?
