Hi Brock, I'm no expert in ALSA stuff let alone PA ALSA, but it looks like this is the problem: Error opening the sound device: Invalid sample rate (err=469996) In that case then you can probably experiment with different sample rates to see which are supported. In the old days, many devices only support 11.025 Hz so this is a good candidate to try: $ pjsua --snd-clock-rate 11025 --ptime 40 $ pjsua --snd-clock-rate 22050 --ptime 20 etc The ptime argument is important for the above sampling rates, since for example with clock rate 11025 we will have non-integer number of samples if we use the default 20ms ptime (1 frame=11025*20/1000=110.5) Cheers Benny On Wed, Aug 26, 2009 at 12:25 AM, Brock Denson<Brock.Denson at csr.com> wrote: > Hi, > > Having problems with alsa and pjsip.?
