Title:
  headset microphone is not recognized in headset-jack

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I'm using Ubuntu 16.04 on a Lenovo ThinkPad T450s. This notebook has a
  combined headphones/mic "headset"-jack as used by pretty much every
  smartphone nowadays.

  I have a Plantronics-Headset HW251/A - SupraPlus Monaural and a 4-pin
  3,5mm jack cable, made for use with PCs.

  When connecting the headset to the notebook, I get audio but the mic
  is not recognized.

  In contrast, when I boot Windows 7 on the same machine, the headset 
(including mic) works fine.
  Moreover, the headset works fine connected to an Apple MacBook Air.

  In contrast, I also have an Apple Earphones-Headset which came with an
  iPhone, this also works with the ThinkPad under Ubuntu.

  By saying "not recognized", I mean that in the audio settings of
  Ubuntu, when plugging in the Plantronics headset, no audio input
  "microphone" comes up and the internal mic of the notebook is still
  used.
