What to test and what a pass actually tells you

Run the test closest to the symptom. A passing result narrows the diagnosis; it does not certify the entire device.

Webcam TestOpen your webcam locally to verify that the browser can access and display a live camera stream.

A pass proves this browser received live camera frames; app selection, permissions or capture mode become more important if one app still fails.

→
Webcam Resolution TestCheck the active video track resolution your browser receives from the camera.

A pass proves this browser received live camera frames; app selection, permissions or capture mode become more important if one app still fails.

→
Webcam FPS TestEstimate the actual delivered webcam frame rate.

A pass proves this browser received live camera frames; app selection, permissions or capture mode become more important if one app still fails.

→
Microphone TestCheck whether your browser can detect your microphone and receive live audio.

A pass proves the selected input delivered audio into this browser session; app routing or processing becomes the next branch.

→
Microphone Recorder TestRecord a short clip locally and play it back to verify your microphone path.

A pass proves the selected input delivered audio into this browser session; app routing or processing becomes the next branch.

Model-specific problems

Start with the symptom people actually search for

These paths combine this model's documented limits with live evidence, instead of copying a generic troubleshooting checklist.

Logitech C920 works in browser but not ZoomIf DeviceOK receives live C920 video, a completely dead camera and basic OS/browser detection are less likely. Zoom camera selection, permissions, another app holding the camera, or app-specific processing become higher priority.

Evidence handoff

If the browser cannot reach the suspected subsystem

Keep the browser result as one observation, then move to the operating system or manufacturer diagnostic that can see the protected hardware state. Do not interpret an unsupported browser API as a failed component.
