Sonos Arc Height Channels

I read a rumor somewhere that Sonos intends to issue a firmware update for the Arc that would allow for a volume slider in the S2 App to independently control the volume of the height channels (upfiring drivers) on the Arc. Can someone please confirm if they have knowledge of or have heard that is true. Thanks in advance

    Hi @Shimmer BFF 

    Thanks for your post!

    Apologies for the delay - I was waiting until today as I can now say that the S2 update that just came out today does include this new feature.

    I’ve settled on +3 for height and -5 for surrounds for now. 
     

    +4 on my set made the vertical sounds more pronounced but artificially so in my perception. +3 is more balanced

      I did the update to 3.1, see the new selection on S2 for the height volume, but found it does not change or vary the height sound, even though my S2 app does register I am playing a Dolby Atmos Movie. Sonos please make it work.

      @bobmatt What specific Dolby Atmos content are you watching and what device are you watching it from? How far are you sitting from the Arc and how far is the Arc from the ceiling? Are your ceilings flat and without any obstruction like a ceiling fan?

      Hi @Shimmer BFF 

      If you did a manual update, that was just the app - you’ll need to do another manual update for the system. Then, you’ll see it next to surround level in the Arc’s settings under System.

      Wait! What?

      I have my Sonos set to update automatically, the app says my system is up to date. Version 13.1.

      There is no height control. 

      What am I missing?

        @DuranDoranMartell Have you performed the system update in the Sonos app too?

        The height audio level control is located under the Arc’s audio settings in the Sonos app:

        For example - Dolby aAtmos movies from Netflix , into arc and my Sonos 2 app status  tv  (in black and white) movie watching “ Dolby Atmos “ sound .

        Most Dolby Atmos movies are not going to have a lot of height channel activity all of the time. You need to find an Atmos film or show that has a specific scene with clearly defined height channel activity to test out the height channel levels to be able to tell the difference. I recommend Roma on Netflix. It has a pretty active Atmos track and utilizes the height channels pretty well.

        You could also download this Dolby Atmos 5.1.2 test tones video. Put it on a USB flash drive and play it through your TV by plugging it into the TV’s USB port.
