Well, the big issue was that I had missed the MythMusic not having alsa 
support. So, it obviously doesn't work with the alsa directive. Now I've 
got /dev/adsp installed and there is sound coming out. Still some volume 
issues, but that was with some old test mp3's, so they might have a 
funky volume or something (or more alsamixer tweaking I guess). More 
tests later this evening.

The TV issues puzzles me more. It may have had something to do with 
trying to use both nvsound and the intel drivers, but I'm not sure. It 
didn't work before I tried the nvsound stuff as well. But this 
afternoon, recreated the capture card in setup, and then attached it to 
ALSA:spdif, and it magically works. Dunno why. So, now I have sound all 
throughout.

One other question about digital outputs. Will AC3 be automagically 
passed through no matter what? I haven't played with a full surround 
setup yet (will be moving this machine to the home theater tomorrow I 
hope), but the receiver I have it hooked up to doesn't seem to notice 
it's surround coming from DVD's or video's. Also, mplayer seems to 
indicate that the output is down sampled to 2 channel. I'm gonna hunt 
through the mplayer help tonight as well and see if that provides more 
clues though.

Thanks for the help.
