I was able to get optical sound working by following this guide: https://help.ubuntu.com/community/HdaIntelSoundHowto
If I add the line
options snd-hda-intel model=6stack-dig
to /etc/modprobe.d/alsa-base.conf, the SPDIF sound works again. So I'd guess that the autodetection of the sound card model somehow broke in 2.6.35-25?
