this has been for quite a few versions now, but laptops set up their function keys to a special set of characters for calling. each brand codes their function keys differently. I don't know if it has anything to do with what I'm about to say but my laptop is a clevo and to press mute, I have to press fn+f3. with that said, for some reason when I set a button on the controller and choose to bring up the menu to end the bigbox menu to end the game, it always triggers my laptop to mute. I've tried the left stick button to bring said menu up, and ive used the ps button on my controller. on first start of bigbox, pressing either when mapped to bringing up the pause screen menu, triggers mute. But after that one time never again. That is until I go into a game and press those mappings again (any mapping will do to that pause screen). It always goes to the pause screen while at the same time, muting my laptop.
