Yes and no. We're missing the mix plugin, but the share plugin allows to
merge more streams into one device, but the channels are not mixed. Try
this configuration:
server.local {
host localhost
socket /tmp/alsa
}
pcm.shared_left {
type share
slave.pcm "plughw:0,0,0"
bindings {
0 0
}
}
pcm.shared_right {
type share
slave.pcm "plughw:0,0,0"
bindings {
0 1
}
}
pcm.remote_left {
type shm
server local
pcm "plug:shared_left"
}
pcm.remote_right {
type shm
server local
pcm "plug:shared_right"
}
Run aserver and type:
aplay -D remote_left <a.wav>
aplay -D remote_right <b.wav>
You should hear simultaneously two wav files. The first from left and the
second from right speaker.
