Bug#854188: python-pjproject: fail to open sound device

[Eric Le Bras]

Package: python-pjproject
Version: 2.5.5~dfsg-5
Severity: important

Dear Maintainer,

Having installed python-project from testing on a stable Debian, I observed that PJSIP could not open sound device.
Executing the simplecall.py script from pjsip documentation fails. Extracted from logged output (log level=6):
....
17:50:51.638   pjsua_call.c !Making call with acc #0 to sip:192.168.0.8:5060
17:50:51.638    pjsua_aud.c  .Set sound device: capture=-1, playback=-2

Exception: Object: {Account <sip:192.168.0.8:41201>}, operation=make_call(), error=Unknown error from audio driver (PJMEDIA_EAUD_SYSERR)
....

However, I have been able to test the sound device with arecord or aplay, and furthermore I was able to use PJSIP 2.5.5 by compiling the sources. pjsystest and pjsua showed no issue with sound device. I was able to pass all tests from pjsystest, and to make calls with pjsua. simplecall.py script gives this output:
....

20:47:45.261    pjsua_aud.c  .Set sound device: capture=-1, playback=-2

Installation and tests have been performed on an Orange Pi Zero card.
