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..
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
I have made up a patch, but want to confirm all this information before
proceeding. Please let me know your thoughts.
Happiness is like peeing your pants. Everyone can see it, but only you can
feel its warmth
