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

    Awesome, thanks for the LPCM support.

    However, i own a Xbox Series X since yesterday which supports Dolby Atmos output. So now i’m wondering, what would be the prefered output? 5.1 uncompressed LPCM, or Bitstream - Dolby Atmos?

    Well, not sure about the “ofcourse”.

    Bitstream means compression, LPCM 5.1 is uncompressed.

      I have been wondering the same, I only game on the xbox so thinking LPCM may be better, but LPCM 5,1 or 7.1 ?

      Don’t you long for the days when the only options for a coffee were black or white, and for audio formats Stereo or DD5.1?

        That’s not really correct. Bitstream means that the sound is not decoded and needs to be decoded by the audio system. This can be however uncompressed audio like DTS-HD or Dolby TrueHD. If you don’t want to lose Atmos, you need to use Bitstream on the XBox as Atmos metadata is not included in LPCM. For games though I would recommend to use LPCM to prevent any audio sync issues.

        Im going to use LPCM 5.1 as I only play games, should I check “let my receiver decode audio” as well?

         

        Thanks

        Ah ok, if you only play games then LPCM is probably the way to go (there might be games with Dolby Atmos, but I’m not a big gamer myself anymore). I think the “let my receiver decode audio” is only for Bluray playback isn’t it? But I would disable that as well, if you only play games.

          Not a clue I think I have always had it enabled, but I think it is just for the movies come to think of it.
