NAK. I'm afraid, but you're trying to revert the change from 2009:

commit 668b9652be33510a2a42b290dd335d34d38e2068

  ALSA: hda - Create multiple HP / speaker controls with index

  Create multiple "Headphone" and "Speaker" controls with non-zero index
  numbers instead of "Headphone2", etc.

  Signed-off-by: Takashi Iwai <tiwai at suse.de>

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.
