[Dovla273]

Description

It would be nice if we had a way to use bluetooth headphones while playing games

Anything else?

When I tried bluetooth it caused major performance problems (it uses the entirety of internal RAM and some CPU) and caused the firmware to double in size.

That being said, if someone goes through the trouble of writing the audio sink and GUI code for pairing and all that and sends a PR, I would accept it. I'd keep it disabled by default in official releases (unless the issues are reduced) but there's no downsides to having the option for custom builds!
