MacBook Microphone doesn’t work in Teams

For some unclear reason the microphone suddenly stopped working on my MacBook Pro Monterey but only when I was using Teams. Fortunately the solution to this turned out to be remarkably simple, it just wasn’t really where I was expecting it to be.

If you go into the System Preferences and select Security and Privacy, then click the Microphone you will see something like this

In my case Microsoft Teams wasn’t ticked, so I clicked the box as shown and my problem was solved. All it needed then was a quick restart of Teams which the machine did for me and a test call and all was well.

To make a test call in Teams you click on the ellipsis near your profile picture and select Settings, then click Devices and there is a button you can press to make a test call.
