Ok! So, in order to change between speaker and bt headphones, it sounds to me like I will probably have to do some configuration that is not available through the menus in retropie? So although fully doable, it will probably be too much mess for just a short gaming session with headphones on the way home from work for example
Or would it be possible to control this in a smoother way?
Sorry for all the newbie questions. Not yet familiar with linux/retropie...
