Hi all,
I am very new to Alsa and I have been trying to configure my dedicated pc to
produce sound from its analog jack and from the jack located on the monitor
which is connected to the pc with display port. So I have the following
asonund.conf file.
pcm.multi {
type multi;
slaves.a.pcm "hw:0,3";
slaves.a.channels 2;
slaves.b.pcm "hw:1,0";
slaves.b.channels 2;
bindings.0.slave a;
bindings.0.channel 0;
bindings.1.slave a;
bindings.1.channel 1;
bindings.2.slave b;
bindings.2.channel 0;
bindings.3.slave b;
bindings.3.channel 1;
}
pcm.!default {
type plug
slave.pcm multi
}
So with this configuration, if I run the following command line
aplay -f cd -D default /usr/share/sounds/alsa/Front_Center.wav
it works like charm and I can hear the sound from both outputs. However,
when I run any application on the pc, it doesn't work anymore. I mean I hear
nothing. I did a lot of tests but no joy. No sound coming out whatsoever. I
have read that I should have alsa.conf file under /etc/modeprobe.d/ but I
don't have it. Could anyone tell me if I really need this file? If yes, what
should I type inside?
Or what could be the reason not to get any sound out from my applications?
Thanks.
