Useful information from the most recent post to that thread from Dan Ritter:
ftp://download.nvidia.com/XFree86/gpu-hdmi-audio-document/gpu-hdmi-audio.html
There you go; now you can be aware of it.
3.1 Pre-Azalia:
Some older GPUs included a connector to receive S/PDIF audio
from a separate sound card, and route that audio over HDMI. This
document does not cover such devices at all.
3.2. Azalia:
Newer GPUs include a fully-fledged sound card, implemented
according to the Intel HD-audio ("Azalia”) specification. This
document covers such devices.
