Sound from left speaker only

The problem is REALLY weird, but I know the source, I think.

I've tried multiple players, replugging in the speaker wire and messing with where the sound should come from, none helping.

However, I recently got a headset, and I'm pretty sure it's the reason my system reconfigurated itself... The headset has one speaker part (which is weird, I need to return it anyway) and it's on the right side, and when I move the speaker volume to the left side it goes silent.

So for some reason my left speaker = right, and vice versa, and it only wants to give output from the side where I have my headset speaker part.

I hope that was clear enough..

 

Nevermind, magically fixed itself over time . . .
