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'm having the exact same problem on my 16-inch MacBook Pro M1 Max.


Anything I watch on the Apple TV app has a weird rumbling, crackling, or pulsating noise whenever there are low frequencies in the audio.


I can confirm that this happens only in the Apple TV app (not on Youtube, Spotify, or anywhere else) and only when I watch content in fullscreen mode. As soon as I exit fullscreen mode, the crackling stops.


I can also confirm that changing the sample rate to 48 kHz in the Audio MIDI Setup app solves the issue.


Apple, please solve this issue!
