I really don't know what's going on. One day my headphones are working great- and there's nothing wrong with my laptop. The next, no cords are compatible with it at all. And I don't know why. And it makes me frustrated not knowing why.

It's an HP Pavillion dx6500. I think it's happened before, and I foret how I fixed it.

Does anybody know what could be wrong with it? Feedback is appreciated...

Also: I tried a GPS USB cord. It doesn't work either.
