Crackling sound from internal speakers
I have a Macbook Pro (Retina, 13-inch, Mid 2014) that works fine. I have recently updated to macOS Big Sur. It has developed a crackling sound from both the left and right speakers. Have done the basics checked the Audio Midi and Sound settings, done a NVRAM/PRAM reset but both the speakers till crackle, assume and hoping it is not the speakers as both crackle when i change the balance
MacBook Pro 13″, 11.2
