  [20BVCTO1WW, Realtek ALC3232, Black Headphone Out, Right] Underruns,
  dropouts or crackling sound

Status in alsa-driver package in Ubuntu:

Bug description:
  Hello, i'm currently having the same issue on a Thinkpad T450, with
  Ubuntu 15.10 and 15.04

  I connect my headphones to the headphone jack, when i connect the
  headphone jack in the headphone port, i get the same cracking, popping
  sound as startup and shutdown/reboot.

  So, when i boot, i get a cracking, popping sound that overpowers the
  headphones, it still occurs when i shutdown the laptop or reboot.

  The output of alsa-info.sh gives me a different codec instead of the proposed fix information
  0x10ec0292 0x17aa5036 0

  i have
  0x10ec0292 0x17aa5034 0

  I tried the fix with both 0x17aa5036 and 0x17aa5034, on Ubuntu 15.10
  and 15.04 without luck, the symptom stays, the cracking sound appears
  at startup and shutdown.

  I tried fedora 23 and i still have the issue.

  Probably caused by the same issue, i get a static noise in the both
  headphones if i mute it goes away

  Thanks for your help.

  Almost similar issue as specified here
