As previously mentioned, it appears the HG code has an entry for the "ASUS 
P5GD1" mainboard. But its onboard sound vendor/device Ids dont match those of 
the person i was helping. I have double checked the pastebin post, and 
confirmed the mainboard model with the user though.

The _original_ alsa-info.sh run (before the model was forced to 6stack-digout) 
is as follows..

http://pastebin.ca/1021995

There it shows the vendor/device ids as 0x1043, 0x814e .
So according to the current HG code, those IDs would select the "asus" model.
Also, in the same, current HG code, we have..

SND_PCI_QUIRK(0x1043, 0x8196, "ASUS P5GD1", ALC880_6ST)

This shows the correct model name for the mainboard, but (from my experience) 
wrong vendor/device ids.

Perhaps we have to check with the person who originally added that P5GD1 
quirk ?

I have made up a patch, but want to confirm all this information before 
proceeding. Please let me know your thoughts.
