Microsoft Teams Microphone Not Working

Test the microphone outside Teams

Press START above and speak. If the level bar moves, Windows or macOS can hear you and the problem is in Teams. If not, fix the device first.

Quick checks

• Look at the microphone button in the meeting and at your headset's own mute button or cable switch. A Teams-certified headset can be muted in hardware while Teams shows you unmuted.
• In large meetings the organizer can turn off microphones for attendees; you will see a message that you cannot unmute.
• Quit other calling apps, then quit Teams fully from the system tray or menu bar and reopen it.

Teams microphone not working on Windows

1. In Teams, open Settings and more (⋯) › Settings › Devices. Under Audio settings, choose the microphone and speak: the meter under it should move.
2. Use Make a test call on the same page (available for most work and school accounts) to hear a recording of yourself.
3. Open Settings › Privacy & security › Microphone (Windows 10: Settings › Privacy › Microphone). Turn on Microphone access and Let apps access your microphone. Apps installed from a website, including most browsers, also need Let desktop apps access your microphone. Microsoft Teams must be on in the list.

5. If Teams keeps choosing the wrong device, set your microphone as default in Settings › System › Sound › Input, then restart Teams.

Teams microphone not working on Mac

1. Open System Settings › Privacy & Security › Microphone and turn on the app. If it is not in the list, it has never asked for the microphone: quit it, open it again and start a call or recording so macOS shows the request. The app is listed as Microsoft Teams.
2. In Teams, go to Settings › Devices and choose the microphone.
3. After changing permissions, quit Teams with Cmd+Q and open it again; it only reads the permission at launch.
