MacBook Pro 2021 M1 crackling sound from Apple TV app

My new MacBook Pro 2021 M1 16" has recently started outputting crackling sound when playing from Apple TV app. I have found various posts and articles on similar issues but none with actual working solutions or this specific. Here is what is most odd and interesting...

the crackling sound from an Apple TV app video only happens when in FULL SCREEN. If I reduce the display size, normal window or put in PiP then the sound appears to be normal with no crackling. As soon as I move to FULL SIZE the crackling restarts.

I suspect there is a bug on how M1 handles graphic vs sound. If no luck finding a solution then I guess it's back to Apple for a fix or replacement, it's barely a couple of months old.

MacBook Pro 16″, macOS 12.1

I opened up my console app and let the logs roll by. I waited to hear the audio problem and tracked it down in the logs based on the timestamp. I believe this is the actual error:

Process: Music Message: HALC_ProxyIOContext::IOWorkLoop: skipping cycle due to overload

I'm going to try to talk to Apple support tomorrow about this and see if this leads somewhere.
