Webcam or microphone not working in video calls

Most of the time the camera and microphone work fine, and something is stopping the app from using them.

Check in this order

1. A physical privacy shutter over the camera, or a camera or microphone key switched off (common on laptops)
2. Inside the call app's settings, choose the right camera, microphone and speaker
3. Permissions: Windows Settings, Privacy & security, Camera and Microphone, and allow the app; on a Mac, System Settings, Privacy & Security
4. Close other apps that might be using the camera
5. In a web browser, allow the camera and microphone for that site (the icon in the address bar)

Still nothing?

• Restart the computer and update the call app
• Try an external USB webcam or headset to see whether the built-in part has failed
• Update the camera driver from the computer maker's support page
