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. On your device, go to Settings > Privacy & security.

  2. Select Microphone.

  3. Turn on the Microphone access toggle.

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

  5. 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. 

  6. 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

  5. Close all apps and restart your device

    Note: These settings only apply to Mac OS 10.14 and higher.

  1. Open Settings.

  2. Tap Privacy > Microphone.

  3. Make sure the Microsoft Teams toggle is turned on.

  4. Close all apps and restart your device.

Check your browser permissions and settings. You may need to “allow” your microphone to work in Teams.

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 “” in the Search field.

  3. Open the "" group and scroll down to find "" 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. 

Reconnect your microphone

See if your mic is connected in your Teams settings.

Before a meeting

  1. Next to your profile picture at the top of Teams, select Settings and more  Select to see more options > Devices.

  2. Under Audio devices, make sure your mic is selected from the Microphone dropdown menu.  

  3. Select Make a test call to test your settings. Follow the instructions from Test Call Bot and record a short message. The message will play back for you. After that, you'll get a summary of the test call, and you can make changes in your device settings. 


    • The test call feature is currently available in English only. Additional languages are coming soon.

    • Your test recording will be deleted immediately after the call. It won’t be retained or used by Microsoft.

    • The test call feature is currently unavailable on Teams for web.

During a meeting

  1. In your Teams meeting window, select More options  Select to see more options > Settings > Device settings.  

  2. Under Microphone,

    1. Make sure your device is unmuted; and 

    2. Make sure your device is selected from the Microphone dropdown menu. 

If your mic isn’t in the Microphone dropdown menu, unplug and plug it back in. If you’re having trouble using a Bluetooth mic, make sure it’s charged and not connected to another device. Then try reconnecting. 

Check sound settings (Windows)

Go to your Windows settings to make sure your microphone is enabled and unmuted. 

  1. From Windows Start, search and select Sound settings.

  2. Go to Input,

    1. In Choose a device for speaking or recording, select your mic. If you don’t see your mic here, select Add device to pair it;

    2. Next to Volume, make sure your mic is unmuted.

If you’re still having trouble, try re-enabling your speaker by going to Advanced > More sound settings. In the Recording tab, right-click your mic. Then select Enable.

Check remote desktop settings (Windows)

  1. From Windows Start, search and select Remote Desktop Connection.

  2. Open the Local Resources tab.

  3. Under Remote audio, select Settings….

    1. Under Remote audio playback, select Play on this computer.

    2. Under Remote audio recording, select Record from this computer.

  4. Select OK to save changes.

Use your phone's audio

If your mic doesn’t work after trying the solutions above and you see one of the messages below, select Call me back to use your phone’s mic.

Enter your phone number and select Call me to receive a call from Teams that will connect you to your meeting. Your audio will come from your phone, but other content sharing will still take place on your desktop.
