Title:
  [W740SU, VIA VT1802, Mic, Internal] mostly no sound at al

Status in alsa-driver package in Ubuntu:
  Incomplete

Bug description:
  Mostly I get no sound at all when using the internal mic.
  Using sound setting recording level slider I am able to get some (noisy sound).
  With alsamixer I can get (also noisy) recordings by lowering "Internal Mic Boost"

  I have applied (and removed) 
    oem-audio-hda-daily-dkms_0.201502011331~ubuntu14.10.1_all.deb
    options snd-hda-intel position_fix=1
    options snd-hda-intel position_fix=2

  to no avail
