i switched my htpc to 9-STABLE and applied the patch:

pcm0: <Realtek ALC887 HDA CODEC PCM (Rear Analog)> (play/rec)
pcm1: <Realtek ALC887 HDA CODEC PCM (Front Analog)> (play/rec)
pcm2: <Realtek ALC887 HDA CODEC PCM (Rear Digital)> (play) default
pcm3: <NVidia GT21x HDA CODEC PCM (DisplayPort 8ch)> (play)
pcm4: <NVidia GT21x HDA CODEC PCM (DisplayPort 8ch)> (play)
pcm5: <NVidia GT21x HDA CODEC PCM (DisplayPort 8ch)> (play)
pcm6: <NVidia GT21x HDA CODEC PCM (DisplayPort 8ch)> (play)

no regression found, i fully tested my optical output: mp3, ac3, dts no
problem.

exaclty the same thing for me when i try my pcm3-6
it could be realy nice to have nvidia hdmi support first 2 channels and
next 8 channels.
i have an ION2 platform and i'm open to test everything.
