Hi all,
I'm new in PJSIP and I want to make it work on a Rasberry Pi
using a USB audio devices ( 2 channels playback, 1 channel record)
to make it work with a mic entry.
I have tried several configuration compiles:
- Port Audio
- Alsa
But I can't make it properly work.
The test that I've been doing is to start pjsua and connect a
ring tone to the playback device for testing the audio, and connect
the record devices with the playback device for checking whether I
hear me.
Using Port audio, the USB device is correctly detected by pjmedia
but pjsua is unstable and hangs up when I try to connect the ring
tone.
Using Alsa, the USB device is not properly detected, but pjsua is
stable, I hear well the ring tone, but when I try to connect the mic,
it the sound is unintelligible
The arguments that I need to uses were: --capture-dev 10
--playback-dev 10 --ec-tail 0 --stereo --clock-rate 44100
In alsamixer, if I enable the mic sound, the audio is very good.
Has someone any information, link o something that can I help me please ?
Best Regards,
Manolo
