I have issue of crackling sound from the right speaker of MacBook Pro 13 inches 2020. I started getting this problem after downloading macOS Big Sur 11.4. I am considering this is an issue. Any suggestions or solution for it?
I believe it's nothing about software issue, it's all about hardware (speaker) problem. I had same problem since long time, thats why sharing my views to you guys. I solved my speaker problem. I opened my Macbook and opened speakers. I noticed defective speaker was torn from side. When you press speaker, you will notice. I fixed with glue all over the tore side. And it works fine now. Please see the youtube video link below, you will find the solutions I did for my Macbook speakers for crackling sound. All the best.
