LPCM ETA for Arc?

206 replies

LG has released a firmware upgrade for the B9/C9/E9 supporting multichannel PCM passthrough. This is great except Arc doesn’t support it yet.

Because of this new update, my Apple TV decides it should use LPCM instead of Dolby Digital 5.1 with Atmos enabled resulting in only 2.0 audio for non Atmos content. The current only workaround is to disable Atmos and enable it when you want to watch an Atmos file. Very frustrating as the previous firmware had no issue.

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

Not only can I see it in the app, but I can hear it!! Wow, what a difference it makes when playing my Switch! Playing the demo of Hyrule Warriors: Age of Calamity, I can hear the Moblins actually surrounding me! Way to go Sonos!

I’m trying to update Sonos on my iMac running 10.15.7 and I keep getting an “Update failed” error message. Anyone else?

Could be lots of people trying to do the update at once, make sure you update your other devices (iPhone, iPad, etc) so that at least you can get your hardware updated once the software is updated. Then come back to the Mac.

I have updated my SONOS Arc now, but unfortunately my 3 year old Samsung QLED TV does not forward the LPCM signal to the Arc so I still unfortunately only get PCM 2.0 audio.
Thinking about changing TV. Anyone can confirm if you get surround from a Nintendo Switch with an LG GX / CX TV and a SONOS Arc together?

The only other device is an Android which I updated. Still getting the error message on my Mac no matter how many attempts.

Maybe try uninstalling the Sonos app on your Mac then install afresh from the Sonos Support website? Make sure you select to connect to existing system.

yes that becomes the last hurdle for some people - not all TV allow lpcm pass through, so you will need to use an AVR or a new TV. If I recall correctly the ARC only has a single hdmi port and so it means all sound has to pass through the TV so you will now be limited by what your TV can pass through.

I need to update my signature, I have an lg OLED tv now - lg released a software update this year, all lg TV made

from April 2019 now support LPCM pass through
