Hi, First post here. The problem is that I am getting no sound from my left hand PC speaker. The right hand one is playing fine. I have unplugged them from the back of the tower and plugged them in again and this makes no difference, although I did hear some very, very low sound from the left speaker while the plug was halfway back in the tower. I have tried another set of speakers and the same thing is happening with them, so I know the speakers themselves are not faulty. Any help would be much appreciated. Rich.
