So just bought a sonos Arc and have been trying to get Dolby Atmos to work. I seem to have everything setup on the LG tv and v6 box correctly and e-arc out to the soundbar. But have been testing on Amazon Prime - Jack Ryan and the sound is showing as Dolby Plus and not Atmos. Can't think of any other things to try. I don't have the V6 box hard wired to the hub, so its running on wi fi, but have never had any issues with the wi fi connection.
So found out on another forum that the virgin Amazon app doesn't support Arc, even though the blurb says the V6 box does. Ran Amazon Prime from my TV app and Atmos works fine. Just need to check now if the Virgin Netflix app is the same.
Update - Netflix on the V6 box also doesn't pass the atmos signal, but the apps on the TV work fine. Perhaps Virgin should actually amend their blurb to say the atmos sound isn't passed from the apps on their V6 box, it would have saved me a lot of time.
Thought I would see about an upgrade to 360. So logged onto my account/upgrade "use chat it will possibly be quicker" it would possibly be if it wasn't "redded out and not available" So next option, phone the 501 number. 50 minutes still on hold with music. Maybe I'll give it a miss and try another day 🙂
Quick update, got a call back (new one) they are sending out a new remote and the upgrade to 360 is free and included in my current package. So hopefully once I get the remote I can try the upgrade to 360 and see if Atmos works.
