OK, So how my machine is set up and the house etc I can'y always game with my speakers on, so I have a headset. Problem is, I have to move my machine to get to the back to plug/unplug each. If I get one of those 2x 3.mm jack things that takes up 1 hole and gives 2 in return, can I have both my speakers and headset plugged in and they will both work, so I can turn the volume of whichever off on the device?
