Crackling noise coming from laptop speakers + sound distorted

[ToshibaPro]

Hey Guys...

So my Packard Bell Easy Note MX37-S-200 has suddenly started making persistent " Crackling " and " Popping" noises from the moment I boot it. The noise is coming from the speakers and the sound is now distorted. I have very recently got it back from the repair shop after having my AC jack replaced... I would really like to rule everything out before I start pointing fingers at the repair guy

Things I have tried - Disabling sound driver - Noise was still there and laptop just installed it again.

Running avast scan through it - Scan picked up nothing.

Played with the sound setting - Nothing changed noise still there.

Plugged in PC speakers - Noise still coming from laptop but sound came out of the speakers fine.



I have noticed also that when the laptop first starts up the noise is louder and more spaced out. I'm wondering maybe whether it is the fan? But I don't no why the noise would be coming from the speakers.



Would really appreciate any help
Thank you

My guess is that based on the information provided that the wires for the speakers have either been damaged or crossed in some way where they are touching something they shouldn't causing distortion. My advice would be to take it back and tell them whats going on and make sure to have them fix it for free if they opened it and caused this problem.
