If you're having trouble hearing audio in Teams, you might be having a problem with your microphone. Here are some solutions to get you back on track.

Check for updates

If you're having trouble hearing sound from your microphone, first make sure you have the latest Windows update or Mac OS updateand Teams app version installed.

To check for updates in Teams, go to your profile picture in the upper-right of the Teams app and select Check for updates. Updates typically install in the background if they're available.

Note: For troubleshooting with Teams in Virtual Desktop Infrastructures (VDI), please talk to your IT administrator or go here for more information. 

Check if your microphone is in use

To make sure you can use your microphone in Teams:

  • Close all other apps that might be using your microphone (like Skype or FaceTime).

  • If you’re using an external microphone, try unplugging it and plugging it back in.

  • You can often save time and effort by restarting your device.

Make a test call

Making a test call can let you know if your microphone is working properly.

To make a test call, select your profile picture, then choose Settings Devices. Then select Make a test call under Audio devices

In a test call, you'll see how your mic, speaker, and camera are working. 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 go to your device settings to make changes.


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

  • We'll delete your test recording immediately after the call. It won't be retained or used by Microsoft.

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

Troubleshooting for Teams on the web

If you're using Teams on the web, here is something you can do to make sure your microphone and camera are set up properly:

It is important to check your browser permissions and settings. You may need to “allow” your camera and/or microphone to work in Teams.

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.
