I agree with you that it is not something you can fix "on your Mac," but it is fixable.
It is almost 2 months from when I applied my fix from the post -> How to fix choppy audio on MacBook Pro wi… - Apple Community
and it's still working.
I'm thinking that Apple just waits until all 2.4Ghz networks die (will be upgraded to 5Ghz or wifi6), and then everything should work flawlessly :)
In addition to the above, I want to spill my frustration.
This is the last Mac I own!
It is absurd to pay this amount of money and not be able to attach as many devices as I want and need. The fact that I can't connect more than one external screen to my MacBook Air is also absurd.
I don't need a MacBook Pro. I love the silence of M1 Air, and I can swallow its price.
There is no perfect "laptop". There is no perfect OS.
For quite some time, I thought that MacOS was the least bad, but it just started losing. It's no longer worth the "premium"!
I'm returning to Linux for my next Upgrade.
