MuseScore refuses to play audio through bluetooth headset.

EDIT: A few hours later it's suddenly working again for no reason whatsoever. I have no idea why. Either way it's fixed.

I just opened up MuseScore today to try messing around with stuff and found that it won't play audio through anything other than the default speakers on my computer anymore, which is VERY ANNOYING for several reasons. I've looked through every guide and fix mentioned on the forum - the soundfont is intact, I've tried every setting in the I/O tab, I've reset to the default settings and reinstalled MuseScore - and nothing has worked to fix it. I've also triple-checked that the headset is the default audio device on the computer - yes, it is - and I've even attempted to disable the other audio devices (which results in MuseScore graying out the play button and leaving me unable to parse scores at all).

The settings in the I/O tab always produce one of two results: if I try to set it to any sort of "default" device (i.e. Windows DirectSound -> Primary Sound Device) or to the headset itself, the play button and other controls are grayed out and the score refuses to play. If I set it to anything else (i.e. MME -> Microsoft Sound Mapper - Input) it plays through the default speakers. I've always restarted MuseScore after applying the sound settings so that's not the issue either.

I've been using MuseScore for several years and have never had any problems with this beforehand. The headset is also not new, I've had it and have been using it with MuseScore for several months.

It's just occured to me that I did have to update my sound driver recently, which could potentially be the source of the problem - however, everything *else* on my computer still correctly plays through the headset, including iTunes/Google Chrome/Skype/Steam/games/etc. I've attached the options I can see on the I/O tab if that helps anyone. ASIO and "skeleton implementation" have no device options which is why I only showed that they're present on the API list.

I'm honestly at my wit's end here and have no idea what else to do. I've been searching for hours through the forums trying every fix but nothing's worked. Does anyone know what might be causing the issues?

Thanks ahead for any help.
