Yes. I do (now).
pjsua_set_snd_dev(0,0) was failing because the default pcm device was "pcm.chan0_play"
This has no capture capability (which is of no interest to me anyhow).
BUT: pjsua_aud.c -> alsa_dev.c must open both a capture and a playback device.
SINCE my default device in asound.conf was
pcm.!default {
type plug
plave.pcm "chan0_play"
}
which was all I needed, alsa_dev.c::open_capture FAILED because it couldn't open a capture channel.
The correct fix (IMHO) is for Benny to alter pj so that open_play_dev() and open_capture_dev() can be called separately.
As a work-around, asound.conf: "chan0_play" changed to "chan0" and things work.

Does ANYBODY use ALSA with pjmumble, and take only 1 audio channel of the hw device?

Subject: PJ/Alsa uses 8 channel on sound device, must use only 1
PJ/Alsa uses 8 channels on my sound device, but it must use only 1, as the other channels are dedicated to other programs and their operations.
I'm still wondering if this "grab all 8 channels" is by design in pjsip.
The other 7 programs share the other 7 channels without trouble.
PJSIP insists on grabbing all 8.
We (the 8 programs) use the same alsa library and the same /etc/asound.conf.
Is there a known cause/remedy for this behavior?
I thinking I wish set_snd_dev took a string instead of an integer, so dev/channel could be specified as
set_snd_dev("0.0","0.0")
instructing use of only the first channel on the first hardware device.
Any ideas where to look?
