Apple TV -> AV-Receiver -> Projector + Sonos Arc

I need an advice on building a home theater system with Dolby Atmos support...

I'm planning to use Apple TV (gen 5) as a source of AV-signal to my Denon AVR-S950H receiver. It has two HDMI HDCP 2.2 outputs with eARC support. I want to use one of them to connect a projector and the second one to connect Sonos Arc.

All components support Dolby Atmos and theoretically everything should work, but I'm not sure about that...

Does anyone have any thoughts on whether Dolby Atmos will work in this type of configuration?

Unfortunately, that’s not going to work.  ARC stands for Audio Return Channel, meaning audio is returned from an HDMI input back to an HDMI output.  The HDMI port on the Arc is actually an HDMI output.  Your design is to connect your AVR HDMI output to the Arc’s HDMI output...which won’t work.

Thanks for your confirmation! It’s sad but expected

I would hope that in the future the new devices from Sonos will support additional interfaces

I know this is an older thread, but we need more cases like this on the internet for Google research.  I wish my case were out there more, but it being week 2 of Xbox Series X being out there I had no help.

 

One more point of confirmation here that it doesn’t work.

 

My Involved Equipment:

-Xbox Series X

-Sony XBR65X900F

-Sonos Arc

-HDMI splitter

 

 

Intended Use Case (ideally)

Xbox (video + Dolby TrueHD audio signal) → TV

TV via eARC → Soundbar which would send out uncompressed awesomeness.

 

Problem:

Since my TV didn’t support eARC, it could not support Dolby TrueHD with Atmos riding along that codec.

 

Attempted Solution:

Xbox (video + Dolby TrueHD audio signal) → HDMI splitter

HDMI splitter (output 1) → Video to TV 

HDMI splitter (output 2) → Audio to Sonos Arc

 

Why It Failed:
Two reasons:

  1. In the setup for Sonos Arc, it will let you know when it no longer detects a legit HDMI ARC or eARC port.  If at any time it detects you’re not using one, it simply stops working for HDMI.  It still works as a standard Sonos speaker, but not for HDMI.
  2. Video mode switching was going crazy as the one input HDMI was looking at BOTH outgoing HDMIs for video mode information and my TV was going nuts.
