Jim,

  I got my Zotac ION (zION) board working with HDMI while using the nvidia
drivers (180.60, IIRC).
I used Allen' guide on the mythtv.org wiki as guidance.

My experience is abbreviated at: http://www.zoomthingie.com/wordpress/?cat=5

Specifically the post "zION - Now with Sound!"

I made an .asoundrc with pcm.slave= "hdmi" and I had to disable AC3
Passthrough in MythTV otherwise, I got audio problems in HD (and some .avi)
files.

Also, I tried disabling the analog audio (as suggested somewhere I read).
That really caused problems for me, so I re-enabled it.

I'm running Gentoo with the 2.6.30 kernel, so it's alsa 1.0.20, I believe,
and alsa support packages (alsa-util, etc) at 1.0.20.

I was able to get sound from the commandline with:

aplay -d hdmi FatBastard.wav


... Yeah, a Fat Bastard quote from Austin Powers.... It was the first thing
I found. =\
