I had a crackling noise from one speaker on my mid 2015 Macbook pro. Bought a replacement from iFixit, changed it and all was well for about a month or so. Now the exact same crackling has reappeared on the same side again. I dont run full volume music or anything like that. What could be happening?
Let’s see if we can make sure the issue is within the speaker or some other part of the audio circuit. What do you hear using wired headphones?What do you hear with Bluetooth headphones?
