I use wireless headphones for audio, which I occasionally turn off to preserve battery life. If I turn off my headphones with MC running, then I turn my headphones back on and unpause or try to load into a world, the game will crash with a NullPointerException. This seems to be caused by the audio output source being changed mid-game.

After a little more testing I've found the crash also reliably happens if I just leave the headphones turned off. The crash seems to be caused when there is no current audio output source.
