[Bug 1359803] Re: External mic not being used in combo port


This is the ultimate solution to suggest ubuntu include in future
versions. It works for the specific model of the bug Asus 1015E, I've
tried and I guess for other models of notebooks and laptops. No need of
foreign configurations, only edit this file:




options snd_hda_intel model=laptop-dmic

  External mic not being used in combo port

Status in linux package in Ubuntu:
  In Progress

Bug description:
  I'm using Ubuntu 14.04 on my Asus 1015E that only has a combo audio
  port which accepts smartphone type "headsets" (3.5mm TRRS headphones
  with mic on the same wire).

  Ubuntu does not deactivate the built-in mic when I connect my headset.
  It doesn't even use the headset mic and instead keeps picking up audio
  signal from the integrated microphone (that's on my laptop bezel).
