as far as NVidia goes, only the GT2xx series cards support audio via
HDMI where the card is its own sound device. What this means is it
does not need to use an SPDIF passthrough like the previous NVidia
chipsets required for PCI type cards. This is how their onboard chips
have been for a while. The downside is that ALSA is only starting to
support this feature of these chipsets, so getting them to work
basically requires running the latest ALSA release.

If you search this list and google you'll find information on getting
it working.
