I've had this problem ever since I built this computer, and although it's not serious, it's very inconvenient. Anyway, for whatever reason, when I plug in ear phones/headphones in to the headphone jack, the left side is much weaker then the right side. Fiddling around with it while it's in usually fixes it in, but this can take a long time and it's extremely annoying. I opened up the computer and I can't see any visible problems, so, any suggestions? PS: I've tried this with multiple headphones and ear phones, all get the same problem.
