Really bizarre audio issue on my MacBook Pro.
2018 13″ Macbook Pro running Catalina.
When I use my headphones, I hear a crackling noise, and it also is heard through the microphone (so if I’m on a call, others hear the crackling noise as well).
I have tried using other headphones. Here’s the bizarre part though: even when I plug the headphones into a 3.5 mm-to-USB-C adaptor dongle, the issue persists. But when I use USB-A headphones plugged into a USB-C adaptor, there is no issue.
So there appears to be something about using 3.5 mm (aux/headphone jack) input, regardless of whether or not it’s through the laptop’s headphone input or through USB-C, that causes this issue. I can’t for the life of me figure out why this would be the case. And again, I’ve tried using other headphones with 3.5mm inputs and the issue persists.
Any suggestions would be greatly appreciated!
