This has only happened once before, when I took my Macbook 16-inch 2023 M2 Max on vacation, and it randomly started making a crackling noise when I played audio. It's only in my left speaker. This first incident happened over the winter break. Now It randomly starts doing it again for no reason, and its getting on my nerves. Thank you. here is an example of the sound it makes. You have to turn your volume up to hear it. Crackling sound video
