Legend of Tarzan - 4k HDR with Atmos - every 2-3 sec the sound interrups... Very annoying :-( Same for other 4k HDR movies with HD Audio

How are you ripping this movies ? they are blu-ray ? 1080p or 4K

More about Legend of Tarzan 4k bluray:
real or fake 4k
It is not real 4K in any material way due to having a final master at 2K. Studios have upscaled the 2K image to 4K and retouched the content for your 4K UHD TV. You should see some visual improvement over a standard 1080p Blu-ray.

Or forbes review
For starters the picture seldom looks truly 4K in resolution. Many shots, especially those featuring a large depth of field and/or heavy amounts of CGI, look barely HD, never mind UHD. The film’s inconsistency where sharpness is concerned is a constant distraction, too, as well as leaving you feeling routinely disappointed that you’re not getting a true 4K experience.

I would't bother for this title to look at 4k bluray, let alone for some recoding which will look worse that bluray or a remux.
