I have managed to get the optical SPDIF working and posted my solution in
the "spdif and m3n78-em" thread. Have you tried this?
"The kernel module must be loaded with this option:
options snd-hda-intel model=6stack-dig"

When using the onboard graphics on this motherboard I also got lots of
"WriteAudio: buffer underrun" on some HD channels and more or less
unwatchable video. After installing a Gainward 8400GS 512MB card this
problem is solved.
