Microsoft Teams Microphone Not Working
Quick answer
Most Teams mic problems come from the wrong input device, OS microphone permission, or a headset connected after you joined. Plug in before joining, select the mic in Teams device settings, allow microphone access, and use the Test call.
Most likely fix: Connect the device before joining
