I have no audio cracking issues, and it's tragicomic you don't provide much information. Audio cracking can be from source material, it can be RF interference for wireless speakers or headphones. Both the bluetooth bands and Wireless bands are subject to a lot of RF issues. My HomePods get buzzy when someone uses a CB radio nearby (and the Samsung oven and microwave totally blitz out).Will they ever fix the audio crackling sound? It's tragicomic we have machines from 2016 with it and these M1 are still carrying it.
But Apple Music to AirPods Pro, to internal speakers, to airplay speakers - no issues at all when there is no interference
