[mythtv-users] ALSA Sound

[Michael Ford]

Create a .asoundrc file with the following and place it into the home 
directory of the myth user.   Then use ALSA:default or ALSA:spdif in Mythtv 
and Mythmusic.  Also, make sure you turn off "Multi Track Rate Locking" if 
enabled or you will get sound output at the wrong speed.  This will 
effectively output all sound through your optical out so your 
receiver/processor can do all the work.

pcm.!default {
    type plug
    slave.pcm "cards.pcm.iec958"
}

pcm.!spdif {
    type plug
    slave.pcm "cards.pcm.iec958"
}

pcm.!iec958 {
    type plug
    slave {
    pcm "hw:0,1"
    format S32_LE
    }
}
