I have connected my Sonos Beam gen 2 to my LG tv via the HDMI eArc input, However even though the broadcasts from Apple TV are carry the Dolby Atmos signal my sound bar is only playing them in stereo. When I unplug the sound bar the TV will play the sound in Dolby Atmos. When I reconnect the sound bar the sound is only in stereo. The tv is an LGOLED55C14LB

On the LG TV press and hold the configuration button. On the sound menu make sure following is set:
Sound out: HDMI ARC
Additional settings:
DTV Audio Setting: Auto
HDMI input audio format: Bitstream
Digital sound out: pass through
eARC: Enabled
Try those and see if it fixes it.

No worries, enjoy! If you have an apple device or can borrow one, I recommend running trueplay :)
I have run Trueplay but I guess now all the settings have changed I best run it again
Thanks for your help

I now get much better sound, clearer dialogue and even Atmos ( we watched Whiplash last night - oh my)
Thanks again, glad I found the thread

I have the same issue and I have tried the above settings but no joy.
Using LG TV’s internal speakers, when I open Apple TV, Netflix, etc I get a banner telling me that it is both Dolby Vision and another one saying Dolby Atmos. When I route sound through the Arc, it tells me that it is Dolby Vision *only*.
I have set the settings below, but the lack of an on-screen “Dolby Atmos” sign makes me think that something is missing…. Any ideas or else is “Dolby Vision” what I should expect?
Additional settings:
DTV Audio Setting: Auto
HDMI input audio format: Bitstream (I have to have the ARC’s HMDI selected otherwise it is greyed out - which makes sense, I guess as that is the only HDMI which is an outbound data rather than inbound)
Digital sound out: pass through
eARC: Enabled

It turns out that although my TV now only says “Dolby Digital” on-screen and there is no mention of Atmos, when I go to the Sonos App, it says “Atmos”, so I am guessing that it is all ok?
Yes, that’s ok. The TV only displays ‘Atmos’ when the internal speakers are used. The Sonos app will show Atmos when it’s detected, so that’s your only guide really.
it would be great if the LG TV’s displayed Atmos and maybe a volume number, but we’ll have to wait for eARC2 for that…!
I’ve tried the settings above but still only get Dolby Digital 5.1 showing in the Sonos app (like others I’ve proven atmos is there as it’s selectable when routed to internal speakers)
Any thing else I could try?
Answering my own question but might help others, turned out to be a Sky Q box issue. Used apps on TV instead of through Sky and now get Dolby Vision and Atmos.

Sky Q box doesn't support Dolby Atmos on any of the apps, it only works for their own content. Box doesn't do Dolby Vision either, just HDR.
