Title:
  HP Zbook 17 G6 internal microphone causes hard crashes

Status in linux package in Ubuntu:
  New

Bug description:
  Anything that changes the state of the internal microphone on the HP
  Zbook 17 G6 can result in a hard crash of the entire system. This
  includes things like noise reduction being applied by Google Meets,
  but it can be reliably replicated by just changing the volume of the
  microphone until the system crashes. When the crashes occur, the logs
  cut off just as they would if the system's power were completely cut.

  This behavior only occurs with the internal microphone. External
  microphones (both 3.5 mm TRRS and USB microphones) do not exhibit this
  same behavior.

  This behavior has been tested on 20.04, 22.04, 23.04, and 23.10 and
  reliably occurs on kernels 5.4, 5.15, 6.2, and 6.5.

  This is the system device that should be responsible for handling the
  internal microphone.
