Teams or Zoom can't find my camera or microphone

Quick fixes

1. Quit and reopen the app. Right-click its taskbar icon and choose Quit, not just close the window.
2. Close other apps that might be using the camera or microphone.
3. Update the app to the latest version.

Choose the right devices in the app

• Teams: select … > Settings > Devices, then choose your speaker, microphone and camera. Select Make a test call to check them.
• Zoom: select Settings > Audio and Settings > Video, choose your devices, and use Test speaker and Test mic.

Check Windows permissions: make sure Let desktop apps access your camera and Let desktop apps access your microphone are on (articles 42 and 44).

Using Teams or Zoom in a browser? Select the padlock icon in the address bar and set Camera and Microphone to Allow.

Poor call quality

• Echo: use headphones, or lower your speaker volume.
• Choppy video or sound: move closer to your Wi-Fi router, use a cable, or pause large downloads and cloud syncing during calls.
• Robotic Bluetooth audio: see the Bluetooth tip in article 43.
