Recently I saw two Headphones on some HP machines, the 1st Headphone comes from the Front Headphone Jack, the 2nd one comes from the Front Headset Jack, and the current HDA driver will set the same name to them and with different index, just like below: 'Headphone Playback Volume' 'Headphone Playback Switch' 'Headphone Playback Volume' index 1 'Headphone Playback Switch' index 1 'Front Headphone Jack' 'Front Headphone Jack' index 1
This can't be handled by pulseaudio, and pulseaduio already has a path analog-output-headphones-2.conf to handle the 2nd headphone, now we set the 2nd headphone's name to "Headphone2", leave the other headphones unchanged.
The change of hda_auto_parser.c will change the name of Jack.
The change of hda_generic.c will change the name of Volume and Switch.
NAK. I'm afraid, but you're trying to revert the change from 2009:
commit 668b9652be33510a2a42b290dd335d34d38e2068 Author: Takashi Iwai tiwai@suse.de Date: Fri Mar 6 10:13:24 2009 +0100
ALSA: hda - Create multiple HP / speaker controls with index
Create multiple "Headphone" and "Speaker" controls with non-zero index numbers instead of "Headphone2", etc.

I think that PA should be fixed instead try to fix the drivers. The indexes are exactly designed to distinguish the multiple similar I/O.
I cannot find any other driver which uses the Headphone2 control name.
JaroslavOK, got it. I tried to add the index to the pulseaudio in Jan, but not finish yet. If you have time, please take a look at my patches and make a comment on them.

Your changes seem as a good start. Unfortunately, I don't know PA internals, so it would be better, if a PA developer can review those patches.

OK, Thanks.
