You could try the Myth DigitalSoundHowTo, was where I started and I
recommend their .asoundrc. I used that and entered ALSA:mixed-digital
wherever I needed it in Myth. Worked great but not in Xine, since I'm
running an Xbox and it doesn't have a mixer device for IEC958/SPDIF I
had to change the IEC958 in xineconfig to default. After that I can
watch DVD's, LiveTV, play Music and Videos with no issues whatsoever.
Good luck!
