                }

                bindings {
                        0 0

                       4 4
                       5 5
                }
        }
        capture.pcm "hw:0"
}

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




Any ideas how to get it work? I tested with speaker-test -c6 but only the left and right speaker do their job.

So it is what, hdmi to a hd tv, with a 5.1 speaker set
hooked up to the tv audio output?

What happens if you hook up a dvd player to the hd tv
and hook up the speakers to the hd tv audio output?
Do you get 5.1 output, 2.1 output, or 2 channel stereo
output?

(Does the hd tv support 5.1 out?)
