Bluetooth Headphones don't work even though correct device is selected.

First I made sure that my headphones were set as the correct output device, which it was. When I try to play anything back the playback line doesn't move at all. When I click on notes I get no feedback. I turned off MIDI input. When I select a different audio device (such as a microphone) there is still playback, as the mixer shows feedback. It was working fine when I was using a pair of wired headphones (which I broke so I cant use). It's extremely frustrating seeing all these solutions but none of them working.
