My Logitech HD Pro Webcam (C920) worked perfectly with Zoom and my Windows 7 Computer. I had to upgrade to a new Windows 11 Dell Desktop. My C920 Webcam works perfectly on all Mic tests and Recording Tests with the new Windows 11 Computer. However, in Zoom, the mic will stop recording audio after 3 to 5 seconds. Then, it will come back on for another 1 or 2 seconds and then drop again. Dell Technical Support spent two hours trying to resolve the problem and Microsoft Technical Support spent four hours (two different sessions) trying to resolve the problem. I have done everything discussed in these posts, all drivers have been updated, Zoom has been uninstalled and reinstalled multiple times. I have spent 15 hours trying to resolve this issue. I am totally frustrated. It appears my only option is to purchase a separate USB Mic to use along with the Logitech C920. Are there any suggestions?

When in a Zoom meeting on the desktop app one user will see all the thumbnails of the group scrolling very fast within the view of the speaker highlighted.  This isn't the normal view where the thumbnails are in the top bar.  It is within the feed of the speaker themselves and blocking part of the picture.  The thumbnails are also scrolling very quickly.

 suddenly these ines have appeared-- whyi don't know but worse i can't figureout how to get rid of them.   they came after I updated my imac's operating systm butnot immediately after.  when theyfirst appeared I also tried updating my zoom operating z system and that didn'thelp either.  anyone have a solution?
