By just looking at the output of lspci will not tell you if drivers
have been loaded or
working. Better then to check the output of /proc/asound/cards (think it's that)
to see what soundcards has been recongised and drivers loaded for.

The command lsmod will show you what modules has been loaded. The driver
for your card i think is snd-hda-intel, see if that is loaded.
