LPCM ETA for Arc?

Have you done the steps set forth earlier in the thread with the photos?

Sonos are quite slow with software update aye, no LPCM yet

 Hi ewolkoff. Yes, I was excited to see your photos and copy the setup exactly, but unfortunately it did not work for me. My settings on the Apple TV were identical to yours but the Audio/Sound settings on the LG are slightly different, as you can see from my pix.

Once the HDMI is selected there is no sub-menu offered, like in your images. I have to navigate to Additional Settings to find the Pass Through and eARC options.

But now, to add to my woes, I messsed around with the settings on the tv AND the 4KATV and now the Dolby Atmos option is gone from the Apple TV Audio Options - it just offers Dolby 5.1 now. :(

I knew I shouldn’t have messed around with my settings.

Your problem is the pass through setting.  You are “passing through” the LPCM signal to the Sonos, which cannot decode it.  You need the TV to decode it first. Do you have an “auto” choice?

Hi ewolkoff. Apologies for the delay in responding. Many thanks for pointing that out. I have changed it to auto, but, due to my messing around with other settings (basically resetting my 4KATV to default I appear to have removed Atmos from my setup now and can only get Dolby Vision (Dolby Digital 5.1) sound.

I have dismantled all the connections and reattached and simply cannot get Atmos back.

I have tried to reset the Sonos Arc (unplug > hold PLAY and replug > wait for flashing amber and white light – but it just goes straight to green) but it doesn’t delete from the S2 app, in order for me to ‘re-establish’ a whole new setup.

And now the app doesn’t even register the audio going through the ARC. 

I have tried now every variation of setup on the LG, but Atmos is gone.

If you go to your HDMI advanced settings in the LG audio settings, do you have Bitstream enabled or PCM?  You need Bitstream there.  I think on your TV’s settings it would be where it says Sound → Additional Settings → HDMI Input Audio Format

Hi, again ewolkoff. Thanks again for your tremendous help. 

That worked - in that by changing the setting Sound > Additional Settings > HDMI Input Audio Format > Bitstream, I was then able to set the Apple TV to Atmos.

Can you explain how that is possible? That changing settings on one device impacts the options on another (ie, changes to a device downstream affects the primary device (4KATV, LGTV, ARC)?

However, despite Atmos being available from the Apple TV, as soon as I play any Atmos content from it (either via the iTunes Store or Disney, etc) there is no sound coming through the soundbar.

Back to square one. :(

TV is still set to Auto and not Pass Through?  Also are you sure it’s Atmos content?  I have noticed that with this setup DD 5.1 plays sometimes with no sound or no voices until I switch to Pass Through again.  That’s why the system is manual — you have to change the settings to play DD 5.1 vs. Atmos.

The issue before was that you told your TV to only accept a stereo PCM signal.  Apple TV saw that and stopped allowing you to send high bandwidth Atmos signals.  

Hi any idea when the update to support lpcm will be available? After spending nearly €2000 on full surround package to its full potential. It really sucks. If I would have known about this I would never invest that much on this system. 

In the same boat here, just got Arc and I'm very disappointed with the whole Apple TV debacle… would really appreciate the LPCM support soon, otherwise I’m gonna have to return the soundbar, it’s simply not worth the hoops
