Interesting discussion of why Dolby Atmos doesn't work sometimes:

Cables and devices must all support HDMI 2.1, and some Android devices don't.

In general, Dolby Atmos should work fine with HDMI 2.0. It does not require 2.1 except for eARC (return channel) and for 4K/8K resolutions at 120fps/60fps. So HDMI 2.0 should be fine for Dolby Atmos Music. And, yes, all components in the signal path have to support Dolby Atmos.
