I'm not sure if it was an update or something I changed in a config. Anything with 5.1 is great, but music and movies encoded in stereo only play with no sound.

I had the same issue when I upgraded my myth box to Ubuntu 8.04 (it
worked fine before then). I tried all sorts of things. The only thing
that got it to work again was this .asoundrc:
pcm.!default {
type plug
slave {
pcm "spdif"
rate 48000
format S16_LE
}
}
I found it by searching the gossamer-threads archive of the mythtv-users
mailing list. Oddly it was this thread:
http://www.gossamer-threads.com/lists/mythtv/users/175424#175424
where I found it. The OP was having the *opposite* problem (2 channel audio
was fine, but he couldn't play 5.1).
Alsa is a black box to me. I have no idea what the above does. I also don't
know why it was working without this .asoundrc and then stopped working when I
upgraded to Ubuntu 8.04.
I hope the above helps.
