Audio Output Settings on Mac not working

Having trouble with LMMS? Ask about it here.
Hi. Whenever I open up LMMS, I cannot hear any of the sound. I've traced this back to the output resetting itself every time I restart LMMS. (I believe that it is worth noting that I'm using bluetooth headphones).

OSX Sierra v10.12.5
LMMS v1.1.3

EDIT: After rebooting the headphones, it worked.
You're welcome!
