If you're still on myth 0.25, I'm guessing you are running an older 
xorg, which probably isn't doing/capable of full auto, so you'll need to 
update /etc/X11/xorg.conf which the correct device information for the 
add-in card. You didn't mention which card/make/model it is so can't 
give you specifics there.

You mention the audio device is listed by aplay -L, have you used an 
alsa-player/mplayer (or equivalent) to see if you can play any audio 
through the device outside of myth?
