Did you try with Firefox in Troubleshoot Mode? Full browser screenshot showing the issue please.

No, it does not help.

Test on this site. https://webcammictest.com/

The webcam worked, I saw myself but microphone did not work. Not able to hit play, mute, unmute, pause buttons

While you work on this, have you tested Microsoft Edge as a backup for having your video visit?

Yes, for some reason even though connected to Mic my pc shows its not connected. May have nothing to do with browser but Webcam itself. Going to purchase new webcam & see if that solves the problem

Thanks for all the responses & support provided

Show the issue. Post similar screenshots. see screenshots Did you check for new drivers in windows update or try to remove the devices via device manager?

Thanks for all the information. after trying all of the suggestions, I phone for technical support. They tested all the drivers, settings, etc. The webcam was working but not the mic. Despite all attempts continued to show that the mic was no connected. At this point technician felt only solution would be to order a new webcam or the pink mic slot is defective? No other answer. I ordered a new webcam & hoping this resolves the problem. Thanks to all the support I received

Mark it as resolved and have a good day.
