Hello. I just contacted Apple technical support. They tested my iPad online and say it's fine. But they don't assure me that Apple is fixing this anomaly, or even that they know about it. The after-sales department offer me to extend the return period to 30 days, waiting for events.

Hello, I write from Spain. The same thing or something very similar happens to me. I also have an 11-inch iPad Pro M1. I have tried two apple adapters and both fail. They work at first, but after a while there is interference and sound cuts. The sound in the videos also sounds out of step at times. If I disconnect the adapter and headphones, the sound comes out correctly from the device's speakers. A few days ago I communicated it to apple support. I was thinking of requesting the device change. After reading your message and the response, I start to think that it may be a general problem.

I had the same problem with a new iPad Pro 11” using an Apple USB-C to 3.5mm headphone jack adapter for a wired Bowers & Wilkins headphones - stuttering audio and crackling sound. Installed the newest release of iPadOS 14.7 today and it fixed the problem immediately. Hopefully this is the solution.

I also have the same problem. I have 3 iPads; iPad pro 12.9 1st gen, iPad pro 3rd gen and and an iPad air 3rd. I am a professional musician using the iPads to play backing tracks. The iPad pro 3rd gen and the iPad air have separate power and audio plug ins. No problems. The problem occurs when I use a USB-C to 3.5 audio doggle with my iPad pro 3rd gen. I have experienced disruption of play back using the doggle. The interruption ranges from pops to static buzzes. I have used 3 different doggles, 3 different audio cables and 3 different speakers. The problem occurs in each substitution. The iPad has no issues playing through blue tooth. The problem doesn't always happen right away. I had one instance when it did happen at the beginning of a performance. I turned the doggle around and that solved the problem for 1.5 hours, then the problem started again. I've had the iPad pro 3 gen replaced once already. Usually it's after 1 hour of playing time that I notice the disruption in audio.

I have the same problem with new IPad Air. I switched my headphones and bought a second apple branded dongle but the same problem. If I unplug and the plug the headphones, it solves the problem until it happens again. I’m guessing it’s a problem with the dongle since it doesn’t happen with AirPods. Apple must have skimped on testing or in manufacturing of the dongle.
