Issues with getting SURROUND SOUND TO PLAY DOLBY ATMOS. I keeping getting PCM 2.0
I currently have a surround set up with the Sonos Arc and two SL ones and gen. 3 subwoofer. When I’m playing a movie with Dolby Atmos it is not showing in the sonos app that its coming through as Dolby Atmos. Instead it is showing pcm 2.0.. I have my system playing through a Samsung QLED Tv model Q80 . This is driving me nuts!!! Any suggestions would ge appreciated!
