Audio / Video Overview
Check speakers, microphone input, camera preview, and video playback in one place so pre-call and support-side diagnostics are quick to run.
Microphone and camera features depend on browser permissions, and the page always shows the current permission state.
Everything stays in the local browser session. Recordings, snapshots, and local videos are not uploaded.
