Comment 9 for bug 16670

The submitter (Mikkel Kamstrup Erlandsen) should try passing "ac97_quirk=hp_only"
to the snd-via82xx module.

The person (Fredrik Roos) whose internal speakers are disabled when something
is plugged into the headphone socket could try the same with snd-intel8x0 and
if this doesn't work then he could try the suggestion at:

This involves patching the driver and setting a new quirk value.

Let us know the results !!!
