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

Add another voice to the “please add support for LPCM 5.1” chorus. As a Nintendo Switch owner it’d be really cool to have full surround support.

Blame Nintendo for using a format that cannot be passed over optical, or ARC. They don’t care if you want to take the audio from your TV (that gets it via HDMI) and do something else with it. They don’t want to pay the royalties to Dolby, that’s all.

eARC is the only transport that can handle LPCM 5.1 from a TV to an audio device.

Oh, I definitely blame Nintendo. I just think that given Nintendo’s reputation for listening to customer issues compared to Sonos’, Sonos is way more likely to fix it on their end than Nintendo is. :stuck_out_tongue: Even if Nintendo’s fix would work for far more people at present than Sonos’ fix would given the eARC requirement for supporting LPCM 5.1.

why pay royalties to anyone. LPCM is superior and free.

The playstation 5 and new Xbox are using new 3d Audio codecs that blow Atmos away - I’ve tried the PS5 version and it makes Atmos look like a toy. Whats the point paying a license for that lol

Yep I’m another voicing my annoyance that LPCM has been left out. It’s free and is used across all gaming consoles as default. There is no logic behind why it’s not supported by the Sonos ARC especially with eARC

Oh I agree. I can think of no technical or legal reason that the Arc cannot support multi-channel LPCM, so maybe it will, given more engineering time. At least it is possible with eARC now.

I just hope that people (including myself) don’t buy another (probably inferior) product waiting for this to get sorted.

Getting very close to pulling my preorder now. Just seems crazy that it’s not included.

I’m starting to regret preordering the Arc with basic functionality like this not being included.

I just discovered my TV doesn’t have eARC anyway, so that is a bummer. I’ll have to wait until someone figures out if AppleTV + Atmos + HDMI-ARC + Sonos-Arc = Atmos or not.
