Hello all, I've had the Promedia 2.1 computer speaker system for many years with no problems until recently. The speakers work and so does the subwoofer but there is a loud humming/buzzing sound coming from the subwoofer only. I've tried plugging it into a wall socket separate from all other equipment and with out the satellites connected but the sound continues. I've also checked the fuse and it’s good. Any help in fixing this issue would be greatly appreciated. Thank you.
