camera/microphone access was denied at browser or operating-system level
A permission failure can block perfectly healthy hardware. DeviceOK separates browser permission from whether the device exists and produces a usable signal.
Do not jump to the most invasive fix
Do not reinstall hardware drivers before checking the site/browser and operating-system privacy controls.
Retest the same condition
After permission is granted, rerun the relevant live test and confirm the device produces the expected signal/output.
Rule out the simple causes
- 1
Open the site permission control and set Microphone to Allow.
- 2
Check Windows/macOS privacy settings if the browser still reports denial.
- 3
Reload the page after changing permission.
Work through the problem in order
- 1
Run DeviceOK Microphone Test again.
- 2
If permission is granted but no input appears, continue with input selection, mute, cable/Bluetooth, and OS audio settings.
- 3
If the microphone works here but not in another app, check that app's microphone selection.
If the matching DeviceOK test succeeds, prioritize the affected app, browser policy, operating-system setting, or configuration before assuming complete hardware failure.
If the same capability also fails in DeviceOK and another trusted diagnostic path, broaden the investigation to connection, operating-system/device state, official driver or firmware support, and finally hardware.
