Title:
  [ Dell OptiPlex 7020, Realtek ALC3220, Green Line Out, Rear]
  Background noise

Status in alsa-driver package in Ubuntu:
  Incomplete

Bug description:
  Any time I start Ubuntu, just a  sec before it starts I begin to hear background noise from speakers. And the noise isn't gone until I 
  shutdown the system.

  By the way, when I start listening to any music, I can't get any bass
  (although, I have a speaker system with sub woofer, and it worked fine
  for me on the previous computer).

  A lot of workaround didn't help.
