Hi, I want to use the line in / mic input for playing back sound of my xbox 360 which is plugged to another display via VGA HD AV cable. but sadly it doesnt work and I get no sound how can i setup windows or the realtek drivers to play back sound that comes in from the input devices? i want windows to playback all sounds coming ín from one of the inputs. how? or is there any software that can do that? live playback from incoming line in / mic signal...
