HDMI ARC Does not support Dolby Atmos or DTS:X. They really have to mention that more. The only way to get Dolby Atmos is from a direct connection with something like a Blu-ray player or your computer. If it goes through a tv, it won't support Dolby Atmos.
The manual, use CTRL + F and type atmos to find it, lists what you get with a connection.

HDMI Direct Connection | HDMI ARC
| Optical |

LPCM 2.0 | Yes | Yes | Yes |

LPCM 5.1 | Yes | No | No |

LPCM 7.1 | Yes | No | No |

Dolby Digital | Yes | Yes | Yes |

Dolby TrueHD | Yes | No | No |

Dolby Digital+ | Yes | Yes | No |

Dolby Atmos | Yes |Refer Below| No |

DTS-HD HRA | Yes | No | No |

DTS-HD MA, DTS LBR, DTS: X, and DSD are HDMI Direct Connection only.

Ok, as to why I said refer below for Dolby Atmos on ARC is that there is a difference between Dolby Atmos. So you can encode atmos into either TrueHD or EAC3. If something doesn't support atmos, the system falls back to either TrueHD or EAC3. (TrueHD is
most common in files. HDMI ARC does not support TrueHD + Atmos combo. However, some TVs can support EAC3 + Atmos. So for most files, you'll have TrueHD + Atmos. HDMI ARC will not support TrueHD or Atmos. However, some TVs can support EAC3 + Atmos. However,
you will rarely find this. Your best bet is to directly plug something like your graphics card (atmos must be supported), Blu-ray player or anything that can output Atmos. HDMI ARC is soo confusing to deal with and that's why many people just assume that it
can support atmos. I've heard new software is coming out that may support atmos on arc though.

Explanation:

Dolby Atmos for Blu-ray & Basically everything else - Direct Connection - NO ARC

Dolby Atmos for streaming (Netflix, Amazon Video) - HDMI ARC is okay!

Conclusion: HDMI ARC is limited right now. You should use a direct connection if you want to fully experience atmos on your programs.

Edit: Steaming sites like netflix use DD+ which is EAC3 + Atmos. So you can use HDMI ARC and watch netflix with atmos but... that's pretty limited.

The optical port won't allow him to get Dolby Atmos sound though, so that might be an issue for the OP. ARC (not eARC) doesn't support Dolby Atmos, so maybe that's the problem here?

Very popular receiver, have one too. No atmos for game support and Arcing atmos back introduces too much latency.

Apparently the issue rests with microsoft as Denon has updated the firmware to anticipate the new, updated version of Dolby atmos home cinema for games or “low latency atmos” so it’s called. The One X supports the regular cinema profile.

Dolby Vision and Atmos are now fairly fragmented formats, makes me wonder if Microsoft should ditch them and go DTS:X moving forward.

First of all, the tomb raider thing was a joke based on all the advertising Xbox did on Dolby Atmos when it first came to the console “which it still hasn’t”

This issue appears for gaming “you can literally find a post with like 27k views with hundreds of people saying the exact same thing”

And like I said, I’m using a Sonos arc system.
