Hello,
I've updated my system BIOS to fix some issues, however since then wave audio over (optical) SPDIF is broken, i.e. I can hear the receiver power up but only silence comes out. Audio on the analog jacks work, as does transmitting AC3/DTS data over spdif.
Attached is the codec#0 proc info for the non-working case, as well as a diff of this output between the (old) working and (new) broken bios.
Looks like you set non-audio SPDIF bit accidentally as default. Thus it doesn't work but for pass-thru mode. Try to reset it via iecset utility.
Also, since the update, this message has reappeared (it went away after the sound tree merge early in the 2.6.36-rc phase):
hda_codec: ALC892: BIOS auto-probing. ALSA hda_codec.c:337: hda_codec: connection list not available for 0x1f
This shouldn't be a big problem, but for tracking more, I'd need alsa-info.sh output. Run with --no-upload option, and attach the output.
