Hello,
I have been testing successfully PJSIP on an Orange Pi Zero card. All tests from pjsystest are successfull. I can use pjsua softphone without issue and make calls. The sound capture and line out are correctly handled.
However I have an issue with sound when using PJSUA Python bindings. Here is the output I get with the simplecall.py application:
...
17:37:07.151 sip_transport. .Transport manager created.
17:37:07.152 pjsua_timer .Mutex created

Exception: Object: {Account <sip:192.168.0.8:34629>}, operation=make_call(), error=Unknown error from audio driver (PJMEDIA_EAUD_SYSERR)
If I set log level to 6, here is what I get:
17:50:51.638 pjsua_call.c !Making call with acc #0 to sip:192.168.0.8:5060

Using pjsua command line softphone, the device is opened without error. Here is the log:
17:07:03.797 pjsua_call.c !Making call with acc #1 to sip:0490572429@xxxxxxxxxxxxxx

I noted that the message from pjsua_app.c ..Turning sound device ON is not found when running simplecall.py. Is there something I am missing?
I am using PJSIP 2.5.5 installed from Debian testing.
