[Bug 1356393] [NEW] [XPS M1330, SigmaTel STAC9228, Mic, Internal] volume too low and distorted even with boost

 

Public bug reported:

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.
