Chosen Solution
Hello, I have a macbook pro retina 2013 and in the last few weeks the laptop makes very strange noise. Sometimes it stops and let me work but sometimes I just need to walk away as the sounds won’t stop buzzing, crackling. Just uploaded a video to make it easier to understand. Do you know how I can solve this issue? Do you think if I will change the speakers this issue will be solved? Thank you so much

Sadly your logic board has a problem! You likely had a liquid spill at some point which dripped onto the logic board damaging it. Here’s the location of the audio chip:
It’s on the backside of the logic board from the bottom. Here’s the guide you’ll need to follow to get it out and maybe you can clean the area of the spillage using a soft toothbrush and 85% or better isopropyl alcohol MacBook Pro 13" Retina Display Early 2013 Logic Board Replacement. If that doesn’t do it you’ll need to get a new board.
