Hello,I connected an arc sound system with an apple TV4K and an hd fury arcana beacause my TV doesn’t have e-arc only arc..
With the Netflix application, I choose a film that offers sound in ATMOSBut on the SONOS s2 application it does not mark me “ATMOS” but "PCM Multicannal 5.1”… ?



I have:
Sonos ARC
2 Sonos One
1 Sub
Thanks for your help
