Hello, A few weeks ago my MacBook fell from the front passenger seat when I slammed on the breaks and then it started making a crackling noise every once in a while. It sounded like this https://www.youtube.com/watch?v=rx7Nwp9S… And now its gone worse, it has a constant buzzing noise through the speaker and even when I plug in my earphones in the headphone jack. And the noise increases and decreases by changing the volume. However when I plug in a thunderbolt dock, the noise goes away. https://youtu.be/B-hlTRGn4nc Now, is this something that is user serviceable? If so, which parts and tools do I need and can I get them from iFixit? Thanks for any suggestions.
Here you have a the removal process for the speakers and here the parts to buy to replace it. Is hard to say that your problem is other than the speakers. It does not cost you much to try and see if this will do the work>
