I have a similar problem, in google meet and also zoom.com's test page https://www.zoom.us/test

I can enable the microphone, the page loads, but no microphone sound detected (the bar does not move up with sound). On the zoom page it gets an error about the camera but the camera picture is there.

but this page works flawlessly https://mozilla.github.io/webrtc-landing/gum_test.html

I'm having the same (or at least a very similar) problem. I use Google Messages to place calls. Has worked fine for the last few years. In the last 24 hours, I'm getting the error that the page is "Unable to connect to your microphone" (see image 1). However, looking at the permissions for the page, use microphone is clearly enabled (see image 2).

Any suggestions on what might be causing this error? FWIW, problem is restricted to Firefox -- microphone works in Edge and Chrome.

Issue appears to have resolved itself by clearing cookies and site data. To accomplish this, I went to the web site I was having trouble with, then hit CTRL-I, which launched the "page info" pop up. Under the "Security" tab, I clicked the "Clear Cookies and Site Data" button, which ultimately deleted the cookies and whatnot and logged me out of Google. Reloading the page and logging back in, the problem was resolved.
