UNABLE TO DETECT MICROPHONE PROPERLY SINCE UPDATING TO WINDOWS 11

@Sheema I hate to hear you are having issues with your microphone. You will need to make sure you are on versions 5.9.0 or higher of Zoom to ensure compatibility.
Here is how you can check for updates: https://support.zoom.us/hc/en-us/articles/201362233-Upgrading-Zoom-to-the-latest-version

If the above doesn't resolve the issue, I suggest reinstalling your audio drivers for your device to ensure that there aren't any issues there. 

Here is a link to a Microsoft support article on how to do this on your machine (assuming windows): https://support.microsoft.com/en-us/windows/update-drivers-in-windows-ec62f46c-ff14-c91d-eead-d7126d...

@J-Zoom-ATL I have tried all the above, but still the same. My mic works fine on other apps, its only zoom where cant hear. Upon using earphones, there are muffled sounds. Please check on your end. 

@Sheema I would also try uninstalling the Zoom client and reinstall the client.
