[mythtv-users] Alsa, SB Extigy and AC-3

[Bryan Halter]

I'm trying to get 5.1 sound working with ALSA and my SB extigy.  I have 
this as my .asoundrc and as soon as xine gets to a 5.1 section it 
becomes silent.  If I have it set to downmix I can hear the movie but I 
want to be able to get 5.1 out of the 3 audio jacks.

pcm.usb-audio {
           type hw
           card 1
}

ctl.usb-audio {
           type hw
           card 1
}

pcm.!default {
          type plug
          slave.pcm "dmixer"
}

pcm.dsp1 {
          type plug
          slave.pcm "dmixer"
}


pcm.dmixer {
          type dmix
          ipc_key 1025 # Should be a unique number
          slave {
                 pcm "hw:1"
          }
          bindings {
                   0 0
                  1 1
          }
}
