Fix Teams meeting audio and video before you join

Most Teams audio and video problems can be spotted and fixed before the meeting starts.

On the pre-join screen

1. Check your camera preview. If it's black, make sure the camera's privacy shutter is open and no other app is using it.
2. Open device settings (the gear icon or Computer audio options), and choose the right microphone and speaker, especially if you use a headset.
3. Watch the microphone level move when you speak.

Test ahead of time

• Go to Settings > Devices in Teams and select Make a test call. It records a short message and plays it back.

Still not working?

• Unplug and replug your headset, then reselect it in device settings.
• Close other apps that use the camera or microphone, such as Zoom or another browser tab.
• Leave and rejoin the meeting, or restart Teams.
• On Windows, check Settings > Privacy & security > Camera and Microphone allow Teams.
