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

An ETA on LPCM would be nice. Having similar problem because I have Apple 4K as well.

Sonos, as a rule, doesn’t give ETAs for software updates.

Sonos barely ever announces they are working on something like this, never mind give an ETA. I'm afraid you're just going to have to be patient.

Apologies for jumping onto this thread but my ? Is related to LPCM / ATV4k as well.

I have a 2016 Samsung 60" KS8001 Smart 4K SUHD TV with an Apple TV 4K.

There is no eARC but ARC, accepted there is no ATMOS for me for now till I replace my TV but I want to ensure I am getting the optimal 5.1 experience.

I had a Denon 5.1 wired setup previously and know that due to the speakers I would have experienced surrounding sound more so than with ARC.

The ATV4k has default settings Audio settings and the ARC sounds great so for streaming apps pushing out 5.1 can I expect the ARC to output the same as well or must I be waiting for the LPCM software upgrade?

If you have an Arc, sub and surrounds then you will get excellent DD5.1 providing your TV passes it via ARC or you run optical into the Arc using the provided adapter from the TV optical (If the TV can pass it) or a hdmi audio extractor.

Coming back to the LG conversation; I held off upgrading my C9 to the 3.80 firmware for this very reason. The TVs passthrough for LPCM is of no use to me until Sonos upgrade the Arc in the future. My other option would have been to use the internal TV apps for 5.1 content but I’d rather run the old firmware for a bit longer and save myself the hassle of constantly switching the audio on the ATV. Let’s hope this software upgrade for the Arc will come sooner rather than later.

If you have an Arc, sub and surrounds then you will get DD5.1 providing yourself TV passes it vi ARC or you run optical into the Arc using the provided adapter.

Thanks, just have the ARC so am in effect just getting 2 channel with maybe some 5.1 effects that the ARC is providing?

I have the same issue with my LG B9 and my Apple TV with the Arc. Hopefully Sonos will add this soon. It’s disturbing that such an expensive soundbar doesn’t support LPCM out of the box.
