Setting up spdif can be a bit frustrating. I currently am able to play all
mythtv audio out spdif as well as mplayer output but not xine for some

This is what works for me with mythtv. I have a nforce2 based motherboard.

Get the asoundrc from wilsonet. Yes I know you think its not working. Put a
copy in /home/mythtv and /home/mythtv/.mythtv. Also put one in /root for
your root user.

In mythtv audio page manually key in "ALSA:spdif" for the audio device and
disable the internal mixer. Also uncheck any of the passthru options. At
this point myth internal audio should play. I am not in front of the right
computer to give you the mplayer option to use. Something ahout "-ao hwac3,"
makes it play ac3 streams via spdif. Have not figured out how to play pcm
streams yet.
