A successful browser-media test requires more than one permission prompt. The browser must be allowed by the operating system, the site must be allowed by the browser, the intended device must be available, and the live track must produce useful video or audio.
Use HTTPS and grant only the camera or microphone access needed for the test.
Refresh the list after permission and select the intended webcam or audio input.
Confirm a visible camera preview or a microphone level that reacts to normal speech.
Create a local picture or short audio recording and review the actual output.

FAQ
No. The live camera and microphone streams stay in the browser. A picture or audio sample leaves the page only when you choose to download the local file.
Yes. You can start or stop the camera and microphone independently, so one test can continue when the other device is unavailable or permission is denied.
Browsers can hide non-default devices and return empty labels until a media stream is active or persistent permission exists. This reduces hardware exposure without consent.
Check the physical shutter, lighting, selected camera, competing apps, operating-system privacy, site permission, virtual-camera source, and whether the browser can restart the video track.
Check hardware mute, the selected input, operating-system input level, browser and site permission, Bluetooth or USB connection, and whether another application or virtual audio device controls the input.
Yes. The app can create a local PNG picture and, when the browser supports MediaRecorder, a short local audio sample that you can play, download, or clear.
