Hello,
At home I have a Raspberry PI with Moode Audio installed. I want to play my
audio in my living room, but also in my kitchen where a bluetooth speaker is
located. I understand that this will be out-of-sync. Playing either in the
kitchen/living room is no problem, but I don't get it to play simultaneously.
My config is as following.
#/etc/alsa/conf.d/20-bluealsa-dmix.conf
pcm.btaplay_dmix {
type plug
slave.pcm "plug_btaplay_dmix"
}
pcm.plug_btaplay_dmix {
type dmix
ipc_key 321456
slave {
pcm {
type hw
card 0
device 0
}
format "S16_LE"
rate 44100
}
}
# /etc/alsa/conf.d/btstream.conf
pcm.btstream {
type plug
slave.pcm {
type bluealsa
device "CC:21:19:40:C4:DA"
profile "a2dp"
}
}
# /etc/alsa/conf.d/multi.conf
pcm.multi {
type route;
slave.pcm {
type multi;
slaves.a.pcm "hw:0,0";
slaves.b.pcm "btstream";
slaves.a.channels 2;
slaves.b.channels 4;
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;
}
ttable.0.0 1
ttable.1.1 1
ttable.0.2 1
ttable.1.3 1
}
There also configs that I did not paste here because I think it is not
relevant. That could be wrong of course. The multi type is the last
configuration I tried. To be honest: I have no real idea what I am doing there.
I am just doing some trial-and-error.
Maybe some additional information is helpful.

I have tried to play the multi type PCM with speaker-test and/or aplay without
success. Hopefully someone is able to help.
Kind regards,
Frederik
