Audio & Video Checker questions
Why does the browser ask for camera and microphone permission?
The page needs temporary access to preview and measure those devices. Your browser lets you approve, deny, or revoke that permission.
What should I do if no device appears?
Check the physical connection, operating-system privacy settings, browser site permissions, and whether another application is exclusively using the device.
