Hello again,
I wanted to give an update. When I use the pjsua executable located in
pjproject/pjsip-apps/bin I can play an audio file using the commands:
./pjsua --clock-rate=48000 --play-file=[file.wav]
Then I issue the command
cc 1 0
And I hear the sound file playing. However I noticed this as output:
pjsua_app.c ..Turning sound device ON
This is something I don't notice in my own application, there the only
output I see is
13:08:30.726 pjsua_aud.c !Creating file player: Noise.wav..
13:08:30.728 wav_player.c .File player 'Noise.wav' created:
samp.rate=48000, ch=1, bufsize=4KB, filesize=135KB
13:08:30.729 pjsua_aud.c .Player created, id=0, slot=1
13:08:30.730 pjsua_aud.c Conf connect: 1 --> 0
13:08:30.731 pjsua_aud.c .Set sound device: capture=-1, playback=-2
13:08:30.732 pjsua_aud.c ..Opening sound device PCM at 48000/1/20ms
13:08:30.747 ec0x9d88d0 ...Echo suppressor created,
clock_rate=48000, channel=1, samples per frame=960, tail length=200 ms,
latency=100 ms
13:08:30.753 conference.c .Port 1 (Noise.wav) transmitting to port 0
(Logitech Wireless Headset: USB Audio (hw:0,0) (48KHz))
Do I need to enable the sound device in my C++ code? If so, how?
