Sounds don't work

A few days ago I used my new Bluetooth headphones. Since the exact moment I +un+pluged them all Minecraft sounds don't work anymore. All other sounds still function. (related to any Minecraft version)
I already tried:
-Restarting my laptop
-Restarting Minecraft
-Turning the sounds off and on
-Turning all Minecraft sounds in the options off and on
-Switching other sound options
