I just got my laptop computer back from the HP repair center to fix a broken hinge. The computer was fine for a little bit, but after an hour or so I heard a really loud low buzzing sound which seems to be coming from the front right speaker. I do not hear it when the mute button is on and it seems to start whenever I do something involving audio (like a noise in a program, a tv show or pressing the volume up button).
I never had this problem before I sent the computer in for repairs, is it possible they nicked a wire or messed something up? I reinstalled the audio driver from the website, but it didn't do anything.
Any help would be appreciated!
I have a Pavilion DM4-2070us (Product No. LW475UA)
