Hello everyone! New owner of an Arc + 2 era 300s + Sub mini.
When I play Atmos files on VLC off an hdd connected to the tv, the Sonos app shows Dolby Digital Plus 2.0. When I play Atmos videos on Netflix it shows Dolby Atmos. Xbox Series X shows Dolby Atmos too.
Tv is a Sony X950G https://www.rtings.com/tv/reviews/sony/x950g and files are DTS HD MA TrueHD 7.1 Atmos. I have Passthrough set to Auto (other option is off). I have connected the arc to the E-arc port.
