FWIW, I used mine with a DJTechTools Chroma Cable with a ferrite bead on each end. That did not make a difference.
When I had my Ultralite AVB, sometimes it would go a few weeks without crackling and sometimes it would crackle multiple times per day.

That is similar to what I heard, but not quite the same. In that recording, the noise cycles in volume. In my case it was at a steady level for a random amount of time, never more than a few minutes.
I found an old forum post that seemed to be talking about similar issues on macOS, but it did not have any recordings attached and I don't remember how I found that. So I'm not sure that these issues never happen with Macs.
Unfortunately it seems that MOTU spent too much effort on fancy features and not enough on getting the basics rock solid. Now that I'm back to using my RME Babyface Pro, I'm glad I don't have to wait a minute for my audio interface to boot up. I think something is quite wrong when an audio interface has a nontrivial boot time. All in all, I recommend staying away from these MOTU interfaces.
Fortunately Sweetwater is awesome and took my returned Ultralite AVB for almost a whole refund (minus a $15 fee) months after I bought it and after the screen broke carrying it in a backpack.
