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

      So I decided that I'm returning my Arc.

      It didn’t make me fall in love with it, because of the silly issue here described, and I feel that €900 speaker really should. 

      I may consider revisiting this when LPCM is supported, but not gonna hold my breath.

        come on LG Europe pull your fingers out and release the UK firmware that fixes this.  Yes I know this is a Sonos forum, I wish LG UK has a forums and I’d post over there.

        It’s also off-topic. This thread is about LPCM support on Sonos Arc. Nothing to do with LG...

            Yes me too. I am not sure how the Sonos is doing PCM if it does not support PCM but don’t care as the atmos Dolby sign is displayed and I am now happy.

            I am still waiting for the LPCM update, as it enables higher sound quality than compressed Dolby. People like me, who use an Apple TV, can get either Dolby Digital 5.1 or LPCM. I want Sonos to support the latter, because it enables higher fidelity sound!

              Oh I see. PCM works fine after LG firmware just not lpcm for high sq and Sonos need to fix that as promised. Is that correct.

              I got the physical Apple TV and Dolby on new firmware. Guessing via pcm not lpcm. Is that correct?

              Your TV takes in LPCM (or Dolby MAT because I think that’s how Apple TV sends Atmos), compressed to DD+ probably, and sends it to Sonos (you should see in Sonos app what format data it’s getting).

              for me Atmos was never a problem (LG C9), it’s the 5.1 content that is being flattened to 2.0 :(
