Title:
  [20216, Realtek ALC282, Speaker, Internal] Power-Save buzzing, and
  suspend/shutdown popping

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Hello,

  I'm having a couple issues regarding the audio on my Ideapad Y410P
  laptop. The first issue is that when external audio devices are
  plugged into the headphone jack on the laptop, the internal speakers
  begin making a high-pitch buzzing noise until the device is unplugged.
  I have discovered that I can remedy this issue by disabling "Auto-
  Mute" in alsamixer.

  Another issue I have been having is a faint buzzing sound followed by
  a loud pop that emits from my laptop's speakers upon suspending or
  shutting it down. The volume at the time of shutdown does not have any
  effect on this.

  Finally, when my laptop is running off battery, my internal speakers
  emit a high pitched buzzing sound when the audio is idle. However,
  disabling the audio device power-save feature remedies this problem
  entirely.

  Thank you for your help, and if there is anything I can do to help
  with the process, I would be more than happy to participate.
