Is your mic hearing you?
Click once. The probe asks for microphone permission, names the input device it actually opened, and measures your level for 6 seconds.
Nothing is uploaded — the signal is analysed in your browser and discarded.

Suggested fixes
Applying a fix changes only this page's capture — OS input volume and hardware settings are untouched, and nothing runs without your click.
Run a probe to get suggestions. Applying a fix re-measures for 3 s and shows the change.
