Arc with LG B7 - no Atmos

I just swapped out my playbase with an Arc.  It sounds great, but I am trying to get it to play Dolby Atmos content.  I have a 2017 LG OLED B7 TV that has an ARC output (not eARc).  I have found a few streaming sources with Dolby Atmos content, but it will only play through the TV speakers (when switches to internal speaker). Any help would be greatly appreciated.

David 82- you are correct- so now it reads 5.1, but only for apps on the TV - Vudu, sling, etc.  usually I watch these through the roku.  I can’t believe that all this time I never had the correct sound...thanks so much!!! I’m forever in your debt

you’re very welcome.  it should also work with your Roku - you might check/refresh its HDMI settings to make sure it is detecting the new 5.1 capable path to your Playbase.  i had a Playbase previously and a Roku Ultra at one point with it that worked very well so it SHOULD be possible. :-)

No love with the roku- I have the ultra and the playbase, same as you so I’ll figure it out!  Thanks again!

    Anyone having any success with Atmos?  I have checked every setting possible including on HDMI2.

    Yep - I got my Arc yesterday and it works on my B7. 

     

    Have you double checked that you’ve unchecked the ‘HDMI Deep Colour’ setting on the HDMI channel the Arc is connected to? You need to set the TV to HDMI 2 to do this, and go to Setting - General - HDMI Deep Colour if I recall correctly.

    Here are my settings:

     

    SOUND:

    Dolby Atmos ON

    Smart Sound Mode OFF

    Sound Out Audio Out (Optical/HDMI ARC) You have to click in here and turn Digital Sound Out = Auto and SIMPLINK (HDMI-CEC) On

     

    Magic Sound Tuning OFF

    DTV Audio Setting AUTO

    AV Sync Adjustment OFF

    Did you set the Arc up with Simplink in the Sonos App?

    Just to check with your B7V - did you get sound immediately on plugging in the HDMI2  as well or have to fiddle with settings?  No sound at all for me as yet!  On the plus side the more people it seems to be working easily with the better case I have to say to LG that they need to fix my TV for me I guess!

    I had to do the setup in the Sonos app and it told me I didn’t have Simplink turned on, after that it was fine. Checked I was getting Atmos with Roma on Netflix. All good. Sounds fantastic!
