I have a 2.1 system. So I plug in my subwoofer through the rear audio jack and there are two ports on the subwoofer in which the speaker cables are put in. Now a while back one of the two ports started having this problem where if I plug in any of the speakers it gives out a very loud static noise. Therefore one of the speakers are unusable. I tried alternating between the ports and speakers but it is always was the same port. I like listening to music on my speakers but some parts of the audio are barely recognizable such as the low piano parts of Baba O'Reily by The Who. Pretty annoying. Please reply fast with possible solutions.
