Hi
I don't know if you can me out?
I have a sonos Arc and 2 Sonos one SL as surrounds
I stream dolby atmos from Disney plus the app that works find (very happy)
but i'm getting stereo pcm from the ps4 and blu ray player
I'm running this on a optoma cinemax p2 it’s got ARC
running through a switcher.
Thanks for your time
