Device widget empty after device change

A couple of related (I think) issues.
Qubes 4.1.2
When system first started devices list populated (all but mic).
Once a device is changed (attached, detached, etc.) devices are all removed from list.
Mic is never listed and there is no mic device class. Mic shows in dom0 volume control.

I have checked policy configs and everything looks correct. This used to work before I attempted audiovm and then reverted.
