A quick check before you join

Teams lets you choose your devices on the pre-join screen, but it doesn’t tell you much about how you sound. Run the test on this page to confirm your mic works and to hear a recording of yourself. Then make sure Teams is pointed at the same microphone.

The Teams desktop app also has a test call. Open Settings and more (the three dots next to your profile picture), choose Settings, then Devices, and select Make a test call. A bot asks you to record a short message and plays it back. The test call may not be available if you use Teams in a web browser, which is one more reason a browser test like this one is handy.

How to test your mic for Teams

  1. Test your mic here

    Press “Test my mic”, speak, and record 5 seconds to hear yourself. Note the microphone name shown in the panel.

  2. Open Teams device settings

    In Teams, select the three dots next to your profile picture, then Settings, then Devices. Under Microphone, choose the device that worked here.

  3. Make a test call

    Select Make a test call, follow the prompt to record a message, and listen to the playback. Teams shows a summary of the devices it used.

  4. Check the pre-join screen

    Before each meeting, Teams shows your audio choice. Make sure Computer audio is selected and the mic toggle is on. A headset plugged in after Teams started may not be selected automatically.

Questions and answers

My mic works here but not in Teams. What’s wrong?

Teams is either using another device or is blocked by your system. Choose the right microphone under Settings, then Devices. On Windows 11, open Settings, Privacy & security, Microphone, and make sure desktop apps are allowed to use it. On a Mac, enable Microsoft Teams under System Settings, Privacy & Security, Microphone.

Why is my mic button greyed out in a Teams meeting?

The meeting organizer has probably disabled microphones for attendees, which is common in large meetings and webinars. Raise your hand and ask to be allowed to unmute. It can also happen if Teams has no microphone permission at all.

Can I test my mic for Teams in a browser?

Yes. Teams on the web uses your browser’s microphone access, the same as this page. Allow the microphone for the Teams site when your browser asks, and check the device on the pre-join screen.

Colleagues say there’s background noise on my Teams calls. Can I fix it?

In Teams, go to Settings, then Devices, and set Noise suppression to High. Record a clip on this page to hear what your room sounds like through your mic before and after you move away from the noise.

How do I mute my mic quickly on Windows 11?

Press Ctrl + Shift + M in Teams. Windows 11 also supports Windows key + Alt + K as a system-wide mute in apps that support it, including Teams.
