Alright. So we just went out and purchased an ATI Radeon HD 2400 graphics card mainly because it had a built-in hdmi port with sound.

I got Xorg and Xgl working using the latest drivers from ATI (7.11 released on Nov. 21,2007).

I installed Alsa 1.0.15 since I saw in the changelog it said something about adding support for audio through hdmi on the R600 cards, but it's still not recognized.

Here's lspci
Code:

05:00.0 VGA compatible controller: ATI Technologies Inc Unknown device 94c3
05:00.1 Audio device: ATI Technologies Inc Unknown device aa10

cat /proc/asound/cards
Code:

0 [CK804 ]: NFORCE - NVidia CK804
NVidia CK804 with ALC850 at irq 17

Sound will still work if I use the motherboard's sound, but it won't come through the hdmi cable on the graphics card.

Does anyone else have this card, ATI Radeon HD 2400, and have video and sound working through it?

If not, what other card is available that actutally can play sound through hdmi?
