My microphone isn't working in Microsoft Teams

If you're having trouble hearing others in your Teams calls and meetings, the problem is either with your speaker not working, or with your microphone. If other participants can hear each other well, the problem is most likely with your microphone.  

Here are some solutions to help you get back on track.

Important: For the best performance, make sure you have the latest version of Teams and the most recent Windows update or Mac OS update installed.

Check privacy settings

To use your mic in Teams, you might need to change privacy settings on your device or on the web to give Teams access to it. 

  1. Open your device settings and select Privacy & security > Microphone.

    Shows Mic settings opened in your Windows device.

  2. Turn on the Microphone access toggle.

  3. Turn on the Let apps access your microphone toggle. If Microsoft Teams appears here, make sure its toggle is turned on.

  4. Turn on the Let desktop apps access your microphone toggle.

    Note: If these toggles were already turned on, try turning them off and on again to make sure the settings apply. 

  5. Close all apps and restart your device.

When your microphone isn't working in Windows 10, it might be a problem with your drivers. Go here for step-by-step instructions to check your Windows drivers. 

  1. Open System Preferences

  2. Select Security & Privacy

  3. Under Privacy, choose Microphone on the left

  4. Make sure Microsoft Teams is selected

Note: Microsoft Teams on the web is currently supported in Chrome, Edge, Firefox, and Internet Explorer 11.

Whether you're using Chrome or other browsers (like Microsoft Edge or Firefox), you can start with Settings (or Options) and then find the microphone and camera.  

For example, in Chrome:

  1. Go to Settings > Privacy and Security > Site Settings > View permissions and data stored across sites.

  2. From here, enter “teams.microsoft.com” in the Search field.

  3. Open the "Microsoft.com" group and scroll down to find "teams.microsoft.com" and select it.

  4. Here, set the Microphone and Camera to Allow access to these devices.

Unmute your microphone

If people in a meeting can't hear you, you might be muted. Make sure you unmute your mic before or during the meeting. 

Some devices have a physical mute option on the device itself, so check that your headphone boom is not in the mute position (usually upright or away from your mouth), or that your external mic's physical mute button is not turned on.
