Ah, does it affect both? What happens if you change the pin 0x10? Does it affect the headphone or speaker output?
Pin 0x0f affects both. Pin 0x10 affects neither.
Does the headphone output work with 3.4 kernel at all?
No. I always tested both speakers and headphones with each patch (and without patches). There was never any sound from either of the two.
Also, just to be sure, try the patch below in addition to another. This will disable the COEF setup, and it wasn't applied to previous models.
This patch does the trick! First I tried it with the patch that deletes two lines from hda_codec.c, worked already, but there was no Speaker control. Then I instead tried with the patch that sets pin 0x0f. Sound works and I have a Speaker control. Interesting thing though, the Headphone control does nothing and the Speaker control affects both speakers and headphones. Maybe pin 0x10 is bogus too.
Also interesting, the Auto-Mute control does nothing. No matter what it's set to, when I plug in headphones the speakers go silent. It seems the machine has hardware auto-mute handling.
Thank you for your work, I now have sound again!
