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. 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? What is Compressed Atmos and will it show Dolby Vision & Atmos in Netflix over the HDMI ARC to the Sonos ARC?

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.

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?

What is Compressed Atmos and will it show Dolby Vision & Atmos in Netflix over the HDMI ARC to the Sonos ARC?

Has anyone had any joy getting the Arc to work with this TV?

Although it clearly recognises it is connected to the TV as it asks to ensure simplink enabled no sound via the soundbar.

The TV had previously worked fine via optical with a playbar.

I’ve checked my Arc by plugging it into an old panasonic which it recognises and outputs the sound from so presumably an issue with the LG?

Hoping for some bright ideas as I really can’t afford to replace the TV!

Just watched Mandalorian in Dolby Vision and Atmos

And you’ve got the LG OLED55B7V right? No joy as yet from LG - only response from techical team was have you tried switching from auto to pcm and back again in audio settings…

I’m on firmware version 05.80.55 which looks to be latest version too so no idea what else to do at the mo! At least I can use it via the optical out for now but definitely envious of those able to enjoy the atmos!

I have the 2017 65” b7 oiled.

Have you tried a hard reset? Unplug it and then press the OK button for 5 sec. or there’s a menu reset under General

Yup - just tried again both factory reset and the ok button… no joy at all so far - still at least the ARC looks better on the TV stand than the playbar I guess!
