Messenger Microphone Not Working

Test the microphone first

Press START above and say a few words. If the level bar moves, the microphone is fine and only Messenger needs fixing. If it does not move, the phone or computer is blocking it.

Note for computers: Meta shut down the Messenger desktop apps for Windows and Mac in December 2025. On a computer, Messenger now runs in the browser (facebook.com/messages) or inside the Facebook app for Windows, so the browser's microphone permission is what matters.

Quick checks

• Check that you are not muted in the call (crossed-out microphone).
• Disconnect Bluetooth headphones you are not using.
• Close other apps that use the microphone, including voice assistants and screen recorders.
