Lot of noise from speakers

I have an acer 4520 aspire laptop, with Realktek HD speakers.. Recently, my output speakers are not sounding very clear. There's a lot of disturbance, which increases as i bring up the volume..

Its been less than a year, since i bought the laptop and im facing the problem already. Even with headphones i get the same noise..

Could it be a driver or a hardware problem? How to fix it please i need your suggestions
