Code 10 means the device cannot start. Uninstall the driver, restart and install the latest one from the PC maker.

The device failed to start because the driver is corrupt or incompatible. Reinstalling usually resolves it.

After you make the change, play the Sound Test again to confirm the result. If the problem is still there, add your device, browser and what you tried in the replies so the team can narrow it down.

Step By Step Fix

    Clean reinstall worked. It took me a few minutes, and the Sound Test showed the difference straight away.
