Sonos Arc - music?

In order for music to be “immersive“ it has to be in Dolby Atmos format.  The only streaming service I know of this is Tidal.  I signed up for a 60 day trial yesterday to hear the difference. The DA content is still limited.  Due to not having my sub yet and the current bass issue, I can’t really crank on it yet.  But, it’s a different sound for sure.  I am still getting used to it, so I don’t have a firm judgement yet.  

Does this mean that non-atmos / normal music is limited to just 2 of Arc's drivers (left and right stereo channles) ?

Arc's music doesn't sound good enough with non-atmos music?

How are you playing Tidal via ARC? I have the latest Tidal app on a 2019 Nvidia Shield connected to a 2020 LG with eARC to the ARC and while Dolby Atmos works fine for Netflix, Prime, Plex etc im only getting 2.0 stereo when playing Atmos tracks on the Nvidia Tidal app. Thanks

The updated Tidal App on the Amazon Fire-Stick/Cube 4K now has Atmos support, so maybe check for any updates of your App and/or Nvidia Shield. The Tidal website says this…

Compatible TV-connected devices include:

• Apple TV 4K (running tvOS 13 or later)
• Fire TV (Fire TV Stick 4K, Fire TV Stick 2016, Fire TV Gen 3 2017, Fire TV Cube 1st Gen or 2nd Gen)
• Nvidia Shield TV and Shield TV Pro (2019 and newer models)

The updated TIDAL app is also available on Dolby Atmos enabled Android TVs from Sony and Philips.

Thanks Ken, I had read that also before I posted so i’m surprised its not just working as I have a 2019 shield TV Pro and both the OS and App are latest version. I am searching on Tidal for Dolby Atmos tracks and find a number of Atmos play lists with tracks with the Dolby logo. Some tracks show as Mastered and some HiFi. I am on a 3 month HiFi trial not sure if thats impacting anything but always get 2.0 on the Arc

It seems you already have the Sonos Arc in-hand, so maybe you can help me understand:

Non-atmos / normal music (e.g. mp3) will use only 2 of Arc's drivers (i.e. left and right stereo channles) ?

Arc's music doesn't sound good enough with non-atmos music?

I’m on the 3 month trial too and it’s working okay here. Maybe try logging out the App and back in again sad see if that fixes it for you. 

Using Apple TV.  The tidal app, On the home page scroll down the page, there is a Dolby Atmos section.  The content is limited… some newer hip hop/pop mostly along with some older mix.

Non-Atmos is fine... 

I haven’t explored DA music too much yet… from the little bit I have heard, in some cases it is almost separated by channels too much.

I will do a test this evening and report back. I have the sub and rears also. I do remember hearing some sound though from the rears even when the app shows 2.0. Music playback is set to Ambient not full but I think this only refers to streamed music and not via HDMI
