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

Thanks to everyone for the feedback so far. Support for multi-channel LPCM is in active development. We'll be testing over the next few months to be part of a future software update. We will update the community once it's available.

A few months?

I just got an LG BX and have my Arc plugged into the eARC port - yet when I play any Dolby Atmos content via my Apple TV 4K I get no sound (tried heaps of combinations of settings to no avail).

From what I understand this is due to the arcs lack of LPCM support. So my Arc will be a very large brick until this update is released in a few months?

You could perhaps ‘switch’ audio codec in the Apple TV settings to Dolby Digital 5.1. I believe that should keep things going with surround sound until the multichannel LPCM update arrives.

Okay I’ll give that a go, thanks mate! At least I’ll get some kind of output for now :)

You should be able to receive Atmos from the apps within the TV itself if you want to receive the full sound until the codec is updated. Not ideal, but better than having to wait for the update to be completed.

Hi Scott! I assume this also applies to the Beam?

No point for the beam. Can’t pass 5.1 LPCM over HDMI ARC or optical anyways

The Beam doesn’t support eARC though. So still no dice

I see 12.0.3 is out today. Is this issue addressed in this release?

Still No LPCM support with latest update. I don't expect it for good few months going by Sonos update history

Hey gang,

I’m also in the Apple TV 4k / Arc LPCM boat. Just wanted to leave a post to remind me to check in as soon as possible when this is resolved. Hopefully it’s soon because the Arc is great otherwise if they could just get this working.
