I wouldn't really know how to detect what kind of output there is connected. How about just using one of these mini toggles?
I think in general the miniloti would be more for the nerds that want to have complete controll over the design.
The average musician end user is already scared by the standart barebones axoloti board. A version that requires even more diy for adding like midi and stuff is even more scary for average users.
So I wouldn't worry too much about the end user not understanding how to use it cause it will be mainly used by nerds
Could this maybe mean you could kind of like digitally controll if the out should be hp / line?
That sounds reasonable. I think with micro usb / 2mini jacks one could create something that is very tiny and covers the basics. I do think though that the usb (and the audio ports) should also be accessable via pin headers though. It really bothers me that you can't do this for the usb ports with the current board.
