Do you want me to test this patch? I haven't built a kernel in years,
but can try.

Title:
  Lenovo E50-80 inverted microphone not detected properly

Status in linux package in Ubuntu:
  In Progress

Bug description:
  System: Lenovo E50-80 with Ubuntu 15.10. Tested with both kernel
  4.2.0-22-generic from official repos and 4.4.0-040400rc6-generic from
  Mainline Kernel repo.

  Alsa information: http://www.alsa-
  project.org/db/?f=3088f82a0cf977855f92af9db8ad406c04f71efa

  Internal microphone does not pick up sound by default. When I mute one
  channel, it works (this is not a good workaround since some
  application, such as Facebook Messenger, unmute both channels and set
  them to the same level automatically).

  Adding model=inv-dmic to snd-hda-intel module options does not change
  a thing.

  Hope that helps, tell me if you need more info.
