SonoS Beam gen 2 with two rear speakers (SonoS one) no Dolby Atmos on Netflix

Hi there,

Recentely I bought the Sonos Beam gen 2 soundbar for my LG C1 tv. I connected it with a HDMI ARC cable and I made it surround with my two SonoS one's. The moment I wanted to experience the Dolby Atmos, I figured Netflix is only showing me Dolby Vision and no Dolby Atmos. The moment I unplug the soundbar Netflix is showing Dolby Atmos (since my tv supports this). I wonder if I am doing something wrong, but I thought Netflix would show me Atmos with this setup. Can somebody help me with this or explain why this isn't working?

If you need any more information, let me know!

Thank you in advance!

I won’t promise my suggestions will work.  There are other Community members who are better at the AV stuff than I am.  I am very confident that you will get Atmos out of your setup, but not so confident that it will be my suggestions that get you there!

And don’t forget to check what Sonos says it is getting first.

    Well, it is worth the try and I really appreciate your help. The other community members can also see my post, right? Or is that on another forum?

      Are you using the HDMI cable supplied with the Beam?  Or another with adequate spec?

      If you go ahead and play, what format does Sonos say it is playing?  (Now Playing screen or in About My System)

      @John B 

      When I am playing content that is available in Dolby Atmos (but isn’t showing) the app says that its in ‘stereo pcm’. Once I set my Digital sound output on Automatic, the Dolby Atmos appears! Also the app changes to: Dolby multichannel PCM 2.0. Is this what it is supposed to say?

       

      Thank you!

      No I would not have expected tbat.  In About My System for the Arc Audio In I would have expected  Dolby Atmos (DD+).

      Did you change the other settings as suggested?

      Hm okay. I did change the settings, but I could not find the ‘bitstream’ setting. I am wondering what the problem is.

      I suspect that that setting won't have any effect with an internal app. 

      Is your TV updated to the latest firmware?

      It is fully updated. I see sometimes it is multichannel 5.1

      If you see the Dolby Atmos logo on Netflix, are you then actually selecting the title to play? The preview is only in Dolby Multichannel PCM2.0. Need to start the programme, then check the audio quality in the Sonos app.
