Hey,

Try playing with the model option of the snd-hda-intel module 
(edit /etc/modprobe.conf). My laptop worked with the model=laptop option.

The full list of options is available in the alsa-driver source:
alsa-kernel/Documentation/ALSA-Configuration.txt (http://pastebin.ca/642405)

Good luck,

nick
