How do i fix my weird sound?

Can almost promise ya that those speakers are ruined, but if you wanna be sure, replace them with diff speakers.. if your using a laptop ur prob SOL. But the reason they are prob working on some things and not others is how the speaker cone vibrates... it might be hittin the perfect spot on those songs and sounds to not go out. Or the electrical isn't shorted out enough to stop working and its back and forth. If its a desktop, get new speakers, if its a laptop.. you might wanna get it cleaned out and checked before it shorts out and blows up ... unlikely, but hey ya never know
