Zoom device help

Test your setup before changing Zoom.

Test the hardware path in DeviceOK first, then use Zoom's own device selection and permissions to isolate an app-specific failure.

Test first

Prove the hardware path

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

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

Left Right Speaker TestPlay left and right channel tones separately.

Screen Share TestVerify that your browser can open the screen/window/tab sharing picker and start a local capture stream.
