Deepak, My question was which value u provides for --capture-dev= --playback-dev= Check which alsa snd device is used for audio and provide its number against the switches I mentioned. By default it is -1 but I think in your system default devices are not used for audio. If you are still facing any issue please drop the exact steps used to run Softphone Thanks and Regards, Gaurav -----Original Message----- From: pjsip [mailto:pjsip-bounces@xxxxxxxxxxxxxxx] On Behalf Of DEEPAK BHATIA Sent: Friday, February 22, 2013 1:30 PM To: pjsip list Subject: Re: [SPAM] PJSUA Giving Audio Device Problems http://lists.pjsip.org/pipermail/pjsip_lists.pjsip.org/2010-August/011390.ht ml > 16:14:15.522 pa_dev.c PortAudio sound library initialized, status=0 > 16:14:15.522 pa_dev.c PortAudio host api count=1 > 16:14:15.522 pa_dev.c Sound device count=0 PortAudio not found any sound device...

Just to add, I had skype also installed which I removed, which I guess had captured the audio device.

One more thing check with arecord and aplay to check whether there exist support for Audio Recorder and player in your machine.
