Title:
  Headset doesn't work for HP EliteBook 755 G2

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  My laptop is an HP EliteBook 755 G2 (from mid 2015) that has a
  combined headset (headphone + mic) jack that doesn't work.  The
  speakers work fine and they mute when a headset is plugged in but the
  headphones don't work.

  This problem exists in Xenial Xerus and in 15.04 (I use the MATE
  flavor of both).

  A fix in the kernel has recently been made.  I've already reported the
  problem to the ALSA developers [1] and Takashi Iwai has already
  committed a fix which is currently queued for inclusion in the
  official kernel:

  https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/commit/?id=f883982dc1b117f04579f0896821cd9f2e397f94

  I'd like to ask that this fix be included in Xenial Xerus's kernel.

  If it's helpful, see [1] for more details and links to other people
  having the same problem.
