Question

LG B7 + Sonos Arc and Dolby Atmos

I have a LG 2017 TV with Atmos enabled for internal speakers. In Netflix shows Dolby Vision & Atmos enabled.

I have now a Beam and with the ARC connected and the same movie shows Dolby Vision & 5.1

The TV has only ARC and no eARC.

  1. Does DD+ enables the UP-firing-Ceilling speakers and will I get a sound coming from top, or the sound bar will only give 5.1 and not use the speakers designed for Atmos?
  1. What is Compressed Atmos and will it show Dolby Vision & Atmos in Netflix over the HDMI ARC to the Sonos ARC?

I haven’t gotten my Arc yet.. it was sitting at the FedEx origination warehouse for 5 days.   Now it’s in S Carolina.  I got my other two Sonos speakers - shipped at the same time - on Monday.

Yup gone through all the recommended settings. Not got an iPhone so haven't run trueplay…

As I say when I plugged the Sonos arc into hdmi arc output on another TV instant sound even before setup and getting sound from the LG via the optical/hdmi converter supplied by Sonos... Just nothing from the hdmi arc output on my LG55B7V.. although if connect to hdmi2 when Sonos plugged into it get the Sonos images.

Firmware all updated on TV as well... I guess if it is truly a faulty TV may be lucky and replaced by LG but suspect very unlikely replacement at this price point!

Try AV Sync turn on bypass

Also...HDMI 2 Deep color should be off - in General Settings

 

and there’s a menu item for sound test (last audio menu item)

Yup... Just double checked and redone all of those settings... Still nowt via HDMI arc to the soundbar... Will give LG techs a couple more days to reply then chase them again.

Thanks for the checklist through... Appreciate it and let me know if it works fine on yours when it arrives...

I once tried resetting the audio pn the LG…..I first powered off by unplugging for 30 seconds and then 

Press and hold down the OK button on the TV panel for 5 seconds (bottom center location)

Resetting LG tv Picture and Audio settings only - not channels.

Mine works.   I now am having trouble with the Harmony remote --- it only changes volume on one HDMI.   

 

I remember reading somewhere to set it to a Philips

Must be a fault with my TV then… fingers crossed LG will be supportive!

By the way, I played a Star Wars episode on Disney and got wonderful sound that filled the room.   I looked on the Sonos App and it said Atmos!    yippee!   Slight lip sync issue I need to fiddle with
