What version of alsa are you running?
and what does this show:
on my system I eventually have lines that say:
HDA NVidia, NVIDIA HDMI
HDMI Audio Output
I had to have a newer version of alsa before it was recognized though
(I'm on 1.0.18a, but this was a while ago)
I think this will tell you if you can use the ATI Radeon. I'm not sure
about buying a separate card.
