Basically got a logiteck x-530 and the middle and rear two speakers won;t work at all. I have set my sound card driver software to 5.1 and it also won;t work in games although i have changed the sound to the correct setting in those too. I know the speakers arn;t broken as i tried them with the 5.1 to pohone adapter supplied. Whats do i need to do to get it workin!?
