Title:
  [20AQ0069GE, Realtek ALC3232, Speaker, Internal] crackling sound while
  booting Unity-Desktop

Status in linux package in Ubuntu:
  Confirmed
Status in Debian:
  Confirmed
Status in Fedora:
  Unknown
Status in Suse:
  Fix Released

Bug description:
  Machine is an T440s. Todays Daily Build of Ubuntu Unity, but was also
  on Ubuntu 15.10 Beta

  While booting into Desktop a crackling sound appears (like connect
  speakers or headphones to a music player if not muted) and it sounds
  very unhealthy to the speakers.

  When using Debian Testing I have the issue while booting. With Fedora
  23 Beta its also the same while booting. Always this unhealthy
  sounding crackling noise and then working normal after booting is
  finished. Muting is working, volume selecting is working without any
  issues, just while booting to Desktop there seems to be something not
  working properly while initializing internal speakers.

  On latest Ubuntu 14.04.3 there is no crackling while booting. Just
  booting normally into Desktop. You can hear that the speakers are
  initialized with a very silent plopping sound (as also in Debian
  Stable) but I think I start observing it just because of this
  crackling sound before. I was running Ubuntu 14.04.2 plus LTS Enabled
  Stack before and there were also no such issues.
