Hi
I see that there are several people with different issues on Apple TV 4K → Sonos so sorry if this has been answered elsewhere.
I have an older LG OLED that only has ARC and not eARC support so that is why i bought the Nedis product which seems to be the same as the Orei one.
When I connect my apple tv through this box the sound cuts in and out a couple of times per second it seems and app shows PCM 7.1.
I also have a chromecast ultra 4K and a nvidia shield pro and when using these as inputs for the same sources Netflix/Apple tv+ etc sonos arc performs perfectly with dolby atmos displayed in the sonos app.
Is there a general issue with apple tv 4k directly communicating with a sonos arc ? I know the common setup would be with an eARC supported tv in between but I would think the box would do the same job as the tv - transferring lossless Atmos to the Sonos Arc.
I have tried having the Apple TV connected to the Tv and the Arc connected to the tv then I get sound not cutting in and out but then it is not Atmos sound.
Running out of thoughts here so input is highly appreciated
Regards
Lars
