現象

Camera and Microphone are not working in Windows 11 or Windows 10. This issue is seen on every type of device including desktops, laptops, and tablets. It is not a problem with the peripherals or an issue in Windows. This is a result of the new privacy changes which Microsoft has implemented in the Windows 10 RS4 April 2018 Update and newer versions that are revoking access to devices such as the camera and microphone.

原因

The privacy settings for camera and microphone in Windows 11 or Windows 10 might prevent apps and websites from using them. Privacy settings give you control over which apps and websites can use your camera or microphone.

解決方法

  1. Check if the Camera and Microphone drivers are installed under the device manager.
  2. Go to the privacy settings in Windows 11 or Windows 10, and make sure the application has been enabled to access the camera and microphone.
  3. Go to Start, then select Settings > Privacy > Camera.
