I have only got sound on one speaker it does not matter if I plug into the back or front it is the same. I tested the speakers and there is no problem with them. I have made sure they are fully pushed into the sockets I have checked the settings in real player every thing seems to be fine but still the same no sound in the left speaker. Could this be a fault on the on board soundcard on my mother board. I have read lots of threads on this problem but no one seems to know the real problem is\nthere anyone out there who knows what he is on about and come up with a solution.
