I am having a lot of inconsistencies with utilizing dobly atmos on my PS5. I have my Samsung TV set up with the PS5 connected to HDMI, arc soundbar connected to TV via eARC, and audio settings on the TV set to “pass through” (has PCM, auto, and pass through settings). On my PS5 it is updated and I have the audio settings as such: HDMI device AV amplifier - Channel 7.1 - audio priority Dolby Atmos.

I have the Era 300s set up in a square room (high vaulted ceiling) approximately 6-10’ from listening position on sonos brand stands. They are facing the TV which sits on a cabinet only entertainment center with the ARC sitting in front. I have trueplay tuned the room both on the sonos app and with the PS5 controller through PS5 settings. 

When I look at my sonos app the only time I can get Dolby Atmos to play is the main menu music on the PS5. After trying multiple media services and apps I had mixed results:

I sound tested a 4k UHD disc (the boy and the heron), making sure the disc audio settings were set to dolby atmos, and the app only showed dolby 5.1. 

On hulu, netflix, and HBO max I played dolby atmos recommended movies and had either PCM 2.0 show on the app, or on MAX the app showed dolby atmos but there was no sound (at all) coming from the era 300s.I attempted to use the native hulu app on my television, in that scenario the era’s were creating sound but the sonos app showed PCM 2.0.

I downloaded apple music on my PS5 an played a spatial audio playlist, it also would only show dolby 5.1 on the sonos app (albeit the era 300s were working).

I have restarted all devices and am unsure of what other steps I need to take to remedy the problem. Is there a device/video/application that I can use to verify atmos is working? I just bought the era 300’s refurbished from Sonos and want to make sure they are working correctly.
