I have acquired a Sonos Arc, my Samsung TV doesn’t do Atmos even over DD but my ATV does. Im happy to use this as the only source of input for the Atmos as it has all the apps etc, before I invest in an (expensive, but cheaper than a new TV!) HDMI audio extractor and EDID emulator I wondered if anyone has tried this route and got it working to split out the sound from ATV HDMI output, so effectively the video goes to TV off one split channel and the audio to Sonos Arc?

The device you’re looking for has been a topic of discussion for a while now, and doesn’t yet actually exist. A company called HDFury is pledging to create the device.
The typical HDMI extractor or splitter will not work as the Arc does not take audio from an HDMI output, it only takes audio through the ARC/eARC channels (which flows opposite of normal HDMI traffic). What is needed, besides a splitter, is a device that can take audio from and input, convert it over to an ARC/eARC signal and send it to the Arc.
