I was testing a music player (Banshee) playing music, and I expected 
"Headphones" to control the audio output to my headphones.

If it is a BIOS pin configuration, then it is *probably* my fault, 
since I messed up my BIOS a few years ago.

The patch seems to work, assuming I reverted the change made to 
sound/pci/hda/hda_generic.c properly (git checkout 
sound/pci/hda/hda_generic.c) and applied the patch properly (git am 
SAVED_MBOX_FILE).

My laptop is a Fujitsu Lifebook T731. Unfortunately, the BIOS doesn't 
know that anymore.

I don't think I'm using dmix (I should be using pulseaudio, since a 
process is shown in ps aux | grep pulseaudio).
