I recently added satelite speakers to my sound system (3.1 to 6.1). I have
alsa configured for AC3 passthrough, and it works flawlessly in Xine playing
DVDs. However when I have surround sound through mythtv, the speaker output
is all mixed up. The most obvious mixup is that the center channel audio
outputs through the left satelite, but all speakers are outputting audio. I
currently have /dev/adsp set as the audio output device and have audio
optical output to my receiver. Here are some settings you might need to help
me out, I am lost on this one.

# For mplayer, ao (mplayer -ac hwac3, -ao alsa9:mplayer)

Thanks in advance for looking at my problem.
