Thanks a lot for sharing this. This enabled audio output. Mic still doesn't show. I'm using a boat bluetooth headset with lenovo windows 11 laptop.
* Open up a Windows Explorer window and paste this in the search bar Control Panel\Hardware and Sound\Devices and Printers and press enter
* Click Devices
* Scroll to bottom of page and click More devices and printer settings
* Find the Bluetooth audio device that is not showing up as an audio output
* Right click on the device and select Properties
* Click the Services tab of the device's properties
* In the list of Bluetooth Services, if you see Handsfree Telephony enabled, disable it and click OK
You might need to play around with disabling other services (maybe Audio Sink) if that doesn't work, but Windows is generally a steaming turd so YMMV.
