On Fedora 33 Silverblue, the integrated microphone with my Lenovo P1 (2nd Gen) stopped working with version 33.20210302.0. This would fail occasionally when running various applications (Cheese, Google Chrome in a toolbox).
How can I help diagnose the root cause of this? Working microphone is an absolute requirement of an OS these days.
