Audio service crashes randomly while starting a call on Pixel Tablet

[Youngblood50]

Initiating a call can crash the audio service, causing the microphone to stop working until a new call is initiated. I noticed this behaviour when using Signal, but other apps may also cause the audio service to crash when accessing the microphone.

I'm unable to reproduce this crash on Pixel Tablet by initiating or answering a Signal voice call. How often does it happen? Is it in main or secondary user? Is Bluetooth audio used at the time of the call?

Main profile, no bluetooth used, just the speakers. It happens like every second call you initiate.
