a Bluetooth microphone/headset is connected but input is not working
If the live test passes, the investigation can usually move away from total hardware failure and toward the affected app, permissions, routing or configuration.
Try the simple causes first
- 1
Run the DeviceOK microphone test and note whether the microphone is detected and whether live input appears.
- 2
Confirm the intended microphone is selected and any physical mute control is off.
- 3
Check the cable, USB port, Bluetooth connection, or headset connector as applicable.
Work through the problem in order
- 1
Run the DeviceOK microphone test and note whether the microphone is detected and whether live input appears.
- 2
Confirm the intended microphone is selected and any physical mute control is off.
- 3
Check the cable, USB port, Bluetooth connection, or headset connector as applicable.
- 4
Check browser and operating-system microphone permissions.
- 5
Try the microphone in one other trusted app to separate an app-specific problem from a device-wide problem.
- 6
If the microphone still fails everywhere, use the manufacturer's official driver/firmware/support path before considering hardware failure.
If the microphone passes the DeviceOK test, prioritize the affected application, permissions, routing, or configuration before assuming the hardware is dead.
If the microphone also fails in DeviceOK and another trusted app, broaden the diagnosis to connection, OS settings, drivers/firmware, and then possible hardware failure.
