So, my friends played a trick on me and set the sound output in Windows on my PC to only go to one speaker. Well, I didn't realize this, so I went through about an hour worth of trouble trying to find out today why one of my speakers wasn't working. I took it out of the back jack, put it in the front, etc. Well, I finally figured out that it was that the output settings had been changed, but now there's no sound!

No sound whatsoever! I can plug these same speakers + sub into my laptops port and it works fine. When I unplug them from my PC, it makes a sound, so I know it recognizes some sort of electrical activity in there. But, no sound is coming out at all, unless I plug them into another computer.

Any ideas?
