Test the selected device and the browser permissions
Device checks help inspect a camera, microphone, display or browser capability. Results depend on the selected device, operating-system settings and the permissions granted to the page.
How to choose your next step
Choose the intended device, check its system input or output level, and stop any recording or live preview after the test.
Common questions about device tests
Why does a working microphone appear unavailable?
Browser permission, operating-system access, a different selected input or another application can affect the result. Check these before assuming hardware failure.
Does one successful test cover every application?
No. Another application may use a different device, input level or permission setting. Test in the application where the device will be used as well.
