Hi,

Hoping someone might be able to guide me in the right direction.I currently have my 5.1 sound card split into 3 separate audio outputs to provide multi room audio. By pieceing various forum posts together, I managed to get something working. My /etc/asound.conf looks like this :

cat /etc/asound.conf
pcm_slave.sixchannels {
   pcm "hw:0"
        channels 6
}
pcm.stereo1 {
        type plug
        slave.pcm {
                type dshare
                ipc_key 5678293
                slave sixchannels
                bindings [ 2 3 ]
        }
}
pcm.stereo2 {
        type plug
        slave.pcm {
                type dshare
                ipc_key 5678293
                slave sixchannels
                bindings [ 4 5 ]
        }
}
pcm.stereo3 {
        type plug
        slave.pcm {
                type dshare
                ipc_key 5678293
                slave sixchannels
                bindings [ 0 1 ]
        }
}

I've played around with info provided from http://slack4dummies.blogspot.com.au/2012/02/alsa-multiple-output-multiple-sound.html and I managed to get all channels from two sound cards playing the same audio.

My question is, can I join stereo2 and stereo3 for into 1 device, For example, play the 1 audio source both in bedroom (stereo2) and lounge (stereo3) at the same time.

Any help greatly appreciated.
