MacBook Pro 16-inch 2021 (MacBookPro18,1), M1 Pro chip OS 12.4 16GB RAM Crackling occurs streaming video (Youtube, you name it, etc), listening to Music.app, in Google Meet, via headphones, onboard speakers, and connected audio a hardware interface (Presonus Audiobox iTwo) for music production. It DOES NOT occur with playback via AirPlay so seems related directly to M1 hardware. Tried an alternate OS account (same issue) but have not revived or restored the firmware via DFU. Seems from the amount of replies here that this is a much bigger issue. Hoping Apple will fix soon as it is completely aggravating.
