There is no buzz if i use batteries. But now i am using it with DC power adapter to serve as my main computer's amplifier. I am using 18 ohm resistors in series with my speaker to reduce loudness

It's almost certainly ground noise; commonly that is due to some AC leakage from the PSU, influencing the ground on the amp relative to the PC ground, and that adds in to the audio fed to the amp.But now i am using it with DC power adapter to serve as my main computer's amplifier.
