Before the call

In Teams, select Settings and more (...) > Settings > Devices (or Audio/Video). Choose the right speaker, microphone and camera, and use Make a test call.

During a call

1. Check you're not muted in Teams, and that a headset doesn't have its own mute switch on.
2. Select More (...) > Settings > Device settings and pick the right microphone and speaker. If you've just plugged in a headset, choose it here.
3. Camera black? Check for a privacy shutter or a camera key (often F10 or a key with a camera symbol) on laptops.

Still not working?

• Unplug the headset or webcam, wait 10 seconds, and plug it back in (try another USB port).
• Windows: select Start > Settings > Privacy & security > Microphone (and Camera) and make sure access is turned on for apps.
• Mac: select Apple menu > System Settings > Privacy & Security > Microphone (and Camera) and turn on Teams or Zoom. Restart the app afterwards.
• Close Teams completely (right-click its icon by the clock > Quit), then open it again, or restart your computer.

If it's still not working, raise a ticket or chat with us and tell us which headset or camera you use.
