Hello, I have been tested MacOS Sonoma Public Beta in my MBP 14 M1 Pro (3 days). And I didn't hear any crackling or ******* on my speakers, although before the update I got them 100% once every 15-30 minutes. When I press memory to yellow zone I din't get any cracking again. I'm hoping this is the fix and when I upgrade to public I'll never hear this again. @mnovaes thank you for link, it's work <3
