Any failing hardware component in your computer could also cause your computer to unexpectedly turn off without warning.If you have recently added any new hardware, try to remove it from the laptop to make sure it is not the cause of the problem.
Go to Device Manager > Bluetooth > Microsoft Bluetooth emulator (mine also had an LE enumerator)
Go to action up top and click disable - mine was the LE one that had to be disabled.
Ignore the warning and it will work. The sound now comes from my Bluetooth speaker.
