Title:
  [XPS M1330, SigmaTel STAC9228, Mic, Internal] volume too low and
  distorted even with boost

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

Bug description:
  Description:	Ubuntu 14.04.1 LTS
  Release:	14.04

  Dell XPS M1330 
  SigmaTel STAC9228
  Internal Microphone 

  Problem: The capture volume is so low on the internal microphone (not the jack) that I can barely hear it even with full boost and speaker volume all the way up.  Additionally, the capture has some distortion.  If I tap on the microphone I can hear the taps, so I know that the capture is working; however, it is not functioning in a manner that allows it to be usable.  
  Everything else works great, including audio output (I can hear music and sound from videos just fine).
  Additionally, when I boot into windows vista, the microphone works perfectly, so it's not a hardware issue.

  I have scoured the forums trying to find a fix, including trying all
  the different models in alsa-base.conf listed for the STAC9228 and
  trying all sorts of configurations via alsamixer and pavucontrol
  including silencing the left/right channel while leaving the other at
  full volume.  I have even tried alternate configurations via
  hdajackretask.  I have now spent several hours on this problem, and it
  is beginning to become frustrating.  Thanks for any help you can give.
