Overview

If call or meeting participants can hear each other speak, but not you, there is likely an issue with your microphone or device/Teams settings.

Check for Updates

For the best experience in Microsoft Teams, make sure your device is fully up to date. This includes installing the latest version of Teams as well as any pending Windows or macOS updates.

Confirm You’re Not Muted

During a meeting, look at the meeting toolbar and check the microphone icon.

  • If the mic icon has a line through it, your microphone is muted.
  • Select the microphone icon to unmute yourself.

Check your Physical Microphone

Some headsets and microphones have built‑in mute controls.

  • If you’re using a headset with an attached mic, make sure it isn’t in the mute position (often upright or rotated away from your mouth).
  • If you’re using an external microphone, check that its physical mute button is turned off.

Review Permissions

Teams needs permission to access your microphone. Depending on how you’re joining the meeting, you may need to allow microphone access in your device settings or browser privacy settings.

Change Device Settings

  1. Open your device settings and select Privacy & security.
  2. Under App permissions, select Microphone.
  3. Turn on the Microphone access toggle.
  4. Turn on the Let apps access your microphone toggle.
  5. Turn on the Microsoft Teams (work or school) toggle.
  6. Turn on the Let desktop apps access your microphone toggle.
    • Note: If these settings were already turned on, try turning them off and on again to make sure the changes apply. 
  7. Close all apps and restart your device.

  1. Open System Preferences on your device.
  2. Select Security & Privacy.
  3. Select Microphone.
  4. Under Privacy, make sure Microsoft Teams is selected.
  5. Close all apps and restart your device.

  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.

Change Browser Settings

  1. In Google Chrome, select Settings.
  2. Select Privacy and security.
  3. Select Site settings.

  5. Select Microphone.
    1. At the top of this screen, make sure your correct device is selected from the dropdown menu.
    2. Under Default behavior, select Sites can ask to use your microphone.

  1. In Microsoft Edge, select Settings and more in the top right corner. Then, click Settings.
  2. Select Cookies and site permissions.
  3. Select Microphone.
  4. Turn on the Ask before accessing (recommended) toggle.
    • Note: If this is turned off, access to your camera will be blocked on Edge.

  1. In Safari, open Preferences.
  2. Select Websites.
  3. In General, select Microphone.
  4. Next to When visiting other websites: select Ask or Allow.
  5. Close all apps and restart your device.

Verify Teams Settings

If you’re using the Teams desktop app, open Settings and confirm the correct microphone is selected and available for use.

Make a Test Call

  1. In Teams, click the ‘…‘ in the top right corner (to the left of your profile icon).
  2. Select Settings.
  3. Select Devices.
  4. Under Audio settings, make sure your mic is selected from the Microphone dropdown menu.  
  5. Click the Make a test call button to test your settings.
  6. 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. 
    • Note: Your test recording will be deleted immediately after the call. It won’t be retained or used by Microsoft.
