Title:
  [Latitude E7240, Realtek ALC292, Mic, Internal] Internal Mic not
  visible

Status in “alsa-driver” package in Ubuntu:
  New

Bug description:
  Sound Settings panel shows "Headset microphone" and "Dock microphone".
  Headset when plugged in works fine (the little dialogue pops up etc).
  Internal microphone is not visible anywhere within the GUI.

  alsamixer "sees" the internal microphone and I can adjust its levels
  but this does not affect the desktop environment.
