Hi Team,
Sorry for the delay, I forgot to mark myself as Out of Office for
yesterday. The customer got back to me on this and indicated that there is
no sensitive or secret information contained in the bug report as is, so it
can be made public. Apologies for any sort of confusion this caused.

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.
