Why These Issues Happen
Chrome blocks camera and microphone by default until you allow each site. Cached decisions or old permissions often block new calls.
Multiple tabs or apps can hold the camera or microphone, causing Chrome to report the device as busy.
Wrong device selection: Chrome may default to a virtual or inactive device. Selecting the correct input fixes most cases.
Browser cache or outdated versions can mis-handle permissions. A refresh or update often clears stale states.

FAQs
How do I allow the microphone in Chrome?
Click the lock icon, open Site settings, and set Microphone to Allow. Select the correct microphone if more than one appears.
Why does Chrome say my camera is blocked?
Chrome may have a prior block decision or another app is holding the camera. Allow camera in Site settings, close other apps, and restart Chrome.
Why is Chrome using the wrong microphone?
Chrome may default to another input. Open Site settings and pick the correct device from the dropdown.
Do I need system permissions too?
Yes. Ensure Windows or macOS privacy settings allow Chrome to use microphone and camera.
Can extensions block my camera or mic?
Yes. Disable extensions that alter audio/video or privacy, then retest.
What if nothing changes after I allow permissions?
Restart Chrome, clear site permissions, update Chrome, and re-allow. Then test with the online tools.
