I have a Dapic 2.1 speaker system, it has it's controls all on the sub-woofer, which is inconvenient for me to reach. Some speakers have a wired remote control, is it possible to make a wired remote controller for it, with an on/off switch, volume controller and a 3.5mm audio output for headphones, which if I connect a headphone to it, the main system has to mute. It also makes a loud noise when I turn it on or off, what can I do to prevent it from doing it. It is at least a decade old and I can't take back to company as they are no longer selling here.
