I have a Sonos Arc, Gen 3 Sub, & two SL Ones hooked up to my Samsung QN90B TV. I can see my settings are correct and Dolby Atmos is turned on. When I play Amazon movies or shows that have Dolby Atmos I can only see Dolby Multichannel PCM 5.1 in my Sonos app. I spent over 2 hours with Samsung and they told me that my settings are correct and that Dolby Multichannel PCM 5.1 is just a name coming from the TV and that if my Dolby Atmos is on and I am using the HDMI eArc port, the sound is in Dolby Atmos. Is this correct?
