You've listed the loaded kernel modules, filtered through grep on the
string 'snd'. So, you can see that the kernel module (equivalent to a
"driver") for hda_intel is loaded. What's a Sigmatel? I'll assume that's
a chipset designation of some sort.

Hmmph!

But with the mention of Sigamtel, trying Teh Ghougle:

http://www.google.com/search?hl=en&q=sigmatel+audio+linux&btnG=Search&lr=lang_en

I didn't read a lot of that, but it sounds like a driver bug, fixed in
Intrepid. Any reason you're running Hardy and not a later release?

Just out of curiosity, how about the output from

$ lspci

which will list all the devices Linux finds on the PCI bus. Should have
specifics on your audio hardware.
