Hi guys, I would greatly appreciate your help on the question below:
Premise, I'm not much of an expert on audio formats, and I probably understand the difference between multichannel PCM and Dolby Atmos. More precisely, I have an LG oled C9 that supports EARC to which I have connected my new sonos ARC; I also connected my blu ray player (sony x800) to a normal HDMI 2.1 input on the TV. Why when I launch a movie (Dune) that is supposed to have audio in Dolby Atmos, on the sonos app S2 comes out Dolby PCM multichannel 5.1? Why not dolby atmos? I know PCM is a lossless format, but my question is: does it already contain Atmos data?
Thanks so much!
