Hey people,
I hope I'm in the right place bothering all
of you, but I need some help with getting a little project
going. Background:
I'm trying to connect my apartments door intercom to a USB
soundcard and then be able to connect to it when someone rings
the door.
I've hit a somewhat significant issue tho: I
was able to compile pjproject 2.1.0 without a hiccup, but there
are several issues interfacing with the soundcard.
First of all, there's zero audio. You can
tell there is a change in status when pjsua is started because
of slight noise setting in, but in-call there's nothing but
silence, the call being ended because of inactivity after a bit.
Testing it with the onboard audio output, there actually is
(Very quiet and bad) audio being transmitted.
When a call is ended, I always get this and
the program seems to hang somewhat:
23:16:10.115 pjsua_aud.c .Closing USB Audio Device: USB
Audio (hw:1,0) sound playback device and USB Audio Device: USB
Audio (hw:1,0) sound capture device
I can play wav's fine through aplay.
pjsystest's "Play Tone" also works, with the hang I described
above occuring. When I use the "Device Test" I get the
following:
1

Sorry we encountered error with the testInvalid sample rate
If anyone can help me out here, I'd really
appreciate it greatly!
Best regards,
