I have 6 3.5mm jacks in the back of my desktop, they're all in different colors (white, purple, blue etc). I used one of them for my speakers, but now its loosened (dont even ask how). I tried to put my speakers in the other jacks, but the speakers still won't make any sound (well, accept a noise, but thats the speakers problem). I know that this isn't the cords or speakers problem since I also tried my cheaphoe headphones. I remember while I used SP2 there was a window that pop'd-up when something was wrong the outputs, it gave the ability to change the output settings, but I can't seem to find something like this in W7. So, how to I adjust the jacks?
