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

    NO LPCM for any of the other HDMI Sonos devices? 

    Multichannel LPCM requires high bandwidth (eARC). So ARC-only speakers can’t do LPCM.

      Nice.  What does this mean for Apple TV users wanting Atmos?

      Party pooper 

      Not at all, it should work now. If it doesn’t, it’s a tv issue.

      But off topic.

      The fact that it now works due to this very patch is off topic?

      Wait… so I have a blu ray disc in the PS4 and it’s a 5.1 enabled movie. But with the update and changed tv settings, it’s still 2.0? Am I confusing myself? 

      Sounds like your settings are wrong and you probably do not have an earc tv?

      I absolutely do have an eARC TV… so I’m unsure what I am doing wrong in the settings. I have it set to “auto” instead of PCM or passthrough and the PS4 is set to Bitstream Dolby.

      You should set to passthrough. 

      I have a Samsung QLED. So the PS4 should be Dolby Bitstream and the TV passthrough?

      Yes, assuming your TV supports Multichannel LPCM passthrough (should). Basically that way TV sends whatever it gets from PS4 directly to Arc. Arc should be able to deal with the audio now. Make sure your eARC is enabled.

      Strange. I have a blu-ray in and it has a 5.1 DTS HD option and it’s still outputting Stereo PCM 2.0. eARC is enabled. On chat to Sonos now…

      Sonos doesn’t support DTS. You want Multichannel LPCM or Dolby Digital 5.1 or anything like that.

      The Arc still doesn't support DTS as far as I know.

      Ahh. I’ll try a blu-ray with DD5.1… additionally, I’ve just put a game on and it’s just “dolby digital 5.1” and not LPCM unless I change the TV to “auto” instead of passthrough… sorry for the questions, I’m a noob!

      No worries, yes, TV will probably flatten most signals into Stereo, hence it’s better as much as possible for signal to just pass through (ha!) directly to audio receiver.

      You want the multichannel pcm output (can’t remember what it is) on the ps4, it doesn’t compress the audio and works now.
