No idea why it's started happening, but I'm getting insane audio crackling. I've tried switching headphones, unplugging them and using the speakers and it's still there. It started two days ago and happens when I do anything, whether it be playing games, opening windows or running a video. It's unbearable and when there's no audio playing there's a faint squeaking sound constantly playing. I've checked to see if there's any interference nearby, I've moved the laptop and it's still there. Can anyone help?
