Microphone isn't working

Hey All,

I have a webcam microphone that shows working in the Windows sound settings, but doesn't appear to be picked up on online test pages or Microsoft Teams.

It is on, it is enabled, and worked last week. It doesn't have any drivers from Logitech's website. I have uninstalled and re-installed the latest version of Teams, with no change. We have tried multiple physical ports. The best Microsoft support could say is to remake the user profile, but I don't believe that is the best way to go about it.

Any help is appreciated.
