sorry about that, i was giving bad advice.

fire up alsamixer, up in the corner there should be a chip entry.

at my place it says realtek ALC883, but i have no clue what it will say for 
you.

also it seems that my enable_msi=1 was jumping the gun as it used the 
targa-dig option setting i had done in my modprobe.conf file (oops).

all in all, it seems that snd-hda-intel is a bitch of a sound chip to work 
with...
