How to Fix a Microphone Not Working in Windows 11

The Problem

Callers cannot hear you, or the input meter in Sound settings never moves when you talk. Speakers work fine—this is an input problem, not no audio / no sound output.

Camera apps cannot see or hear you? Start with webcam not working—laptop privacy keys often kill both.

The Fix

Step 1: Mute Switch and Ports

Headset inline mute off. USB mic on a rear port, not a flaky front hub. Split pink mic + green headphone plugs need the right jacks—single TRRS headsets need a combo port or adapter.

Step 2: Default Input Device

Settings → System → Sound → Input → pick your mic (not Stereo Mix). Test your microphone—bar should move when you speak. Input volume around 80–100%.

Step 3: Privacy

Settings → Privacy & security → Microphone → access on for device, apps, and desktop apps. Allow Teams, Zoom, Discord, and your browser.

Step 4: Classic Sound Panel

mmsys.cpl → Recording → double-click the mic → Levels (small boost if needed) → Advanced → uncheck exclusive control temporarily → disable enhancements if the tab exists.

Step 5: Drivers

Device Manager → Audio inputs and outputs → update or reinstall. USB headset: different port and reboot. Wireless: remove and pair again in Bluetooth.

Step 6: Inside the App

Teams, Zoom, Discord each have their own mic dropdown—match Windows. In Discord, turn off Automatic Input Sensitivity while testing. In Chrome, lock icon on the site → allow microphone.

Step 7: Troubleshooter

Settings → System → Troubleshoot → Recording Audio.
