Recently I bought a bluetooth speaker. When I tried to connect my laptop (Dell XPS 13, Windows 10), at first there was no sound. I tried to disconnect the speaker in playback device in control panel. Then the speaker totally disappeared in playback device and I cannot find it anywhere.
Eventually I solved the problem using the method mentioned in the link below, quite useful! Basically the solution is to change the property of the bluetooth speaker and then it will reappear!
