Buzzing Sound from ASUS Laptop Speaker

[AzrealLPW]

I own an ASUS K84L, which I've had for almost a year and a half. Recently my speakers began buzzing while watching YouTube videos, it was a minor complaint that I ignored but it has gotten steadily worse. Now, anytime my computer is on battery power the speakers continually buzz, made worse by audio files being played. I have tried reinstalling drivers and disabling the microphone with no luck. Is this a hardware issue, or is it something I can fix?
