Multichannel PCM on Arc

Are you really not supporting multichannel PCM on the newly announced Arc?

Why? It’s not a licensing issue this time.

It seems like there is always something missing with your home theater products.

Hi all,

We hear you. With a software update today, Arc now supports multi-channel LPCM, bringing new immersive sound experiences for gaming, Blu-ray discs, and more. To get support for multi-channel LPCM on Arc, download the latest Sonos S2 update from the app store and then update your system in the Sonos S2 app. After updating the app, go to Settings > System > System Updates > Check for Updates.

All the best,

Ditte

+1 for another customer with Sonos ARC + AppleTV + LG 2020 nanocell TV and no Dolby Atmos sounds.  

Do you have the latest firmware? 03.10.60

I have a LG 55NANO866 and I have Atmos…? What are your settings on the tv?

Easier if you tell me your settings because I’ve tried them all. Btw I am talking about the physical Apple TV  not the AppleTV+ app baked into webos. The app works because it supports bitstreaming where as the box uses LPCM which Sonos does not support to date.

I am using the Apple TV 4K, with the audio settings set to Auto, and Dolby Atmos turned on.  My LG Nano91 is set to Passthrough, with eARC on.  I was not able to receive any sound when playing Atmos content until earlier this week when the new firmware update came through my tv.  Once the update was completed, I tried Atmos content on Netflix, Prime and Apple TV+ and was surprised that all formats were working without having to change settings any longer.  So something in the latest update has allowed the Arc to accept the Audio format from the Apple Tv box.

What version of the firmware and TV do you have?

I have 03.10.60

Although I have been told the updates are geographical.  I am located in US.

From what others are saying, the format I am receiving is Dolby MAT from the Apple TV, but it is still nice to have one place to go for all content, rather than using the LG tv apps.

I’ll just have to keep pressing the update every hour until they release a U.K. firmware.

Any update on the LPMC would be most appreciated, just got Arc and I’m very disappointed it doesn’t support it :(
