My recommendation is to concentrate first on getting it to work with 
analog audio output.  Once that's done (i.e. once you know Myth is 
configured/working properly), then modify your ALSA configuration to use 
S/PDIF out.  I.e. walk before you try to run.

With your sound card, renaming /etc/asound.conf and ~/.asoundrc (i.e. so 
you're using all ALSA defaults) should be a good analog test.
