Hi 

I don’t know if my issue is related to the 14.6 update but I noticed today that I had no sound from my surround (play 3) and my sub (Gen 2), only the Arc is working They are still present in the app under the my System view but now sound which every sources

When I reboot each of them, the sound comes back temporary, but when I switch to another source or audio format, thé Sound disappears again. Tried several times, same behavior

Thanks for your help

    Thanks but yeah, I’m not referring to Atmos, just Dolby Digital + (which my TV supports). I can’t seem to get it to activate beyond Dolby Digital 5.1 though since the update … strange

    When I look quickly online I can only find that the KD-55XE9305 supports DTS and Dolby Digital 5.1 - are you sure it supports Dolby Digital Plus?

    Updated software and now everything is showing as playing Stereo PCM (as opposed to Dolby Digital +) via AppleTV 4K. Anyone any ideas how to fix? I previously used to play Dolby Digital + no bother. 

    I can only get regular Dolby 5.1 to play by setting audio mode to ‘16bit’ and Change Format ‘On’ and to ‘Dolby 5.1’ on the AppleTV. Changing either of those settings causes it to just play Stereo PCM.

    Sony Bravia TV audio output settings are set to a/v sync  ‘auto’, digital audio out ‘auto 1’ and Dolby digital plus output ‘Dolby digital plus’ (also audio system prioritisation ‘on’ and sound mode sync ‘on’). TV is Sony BRAVIA KD-55XE9305 HDR 4K TV. NB: this is an ARC connection, not eARC, and Dolby + is the best format I can get. 

    Apple TV doesn’t really do DD+. For DD+ content, it decodes using Dolby Mat and outputs multichannel PCM if your system can support. If you were seeing DD+ in the Sonos app when playing content from Apple TV, your tv was likely set to re-encode whatever it was receiving to DD+. On my LG C1, setting audio output to ‘auto’ instead of ‘passthrough’ or ‘pcm’ results in this re-encoding. If you’re not getting what you’d expect I would look at your tv settings further.

      I seem to think with Apple TV 4K that DD+ (without Atmos) is only available via the uncompressed multichannel LPCM codec which Apple use by default, sadly you cannot use that format, as it requires HDMI eARC support and so the fallback is Dolby Digital 5.1.

      So those are my thoughts that you may need to select the DD5.1 codec instead with the Apple TV 4K. I’m sure others here will correct me if I’m wrong about that.

      I don’t think this has anything to do with the recent Sonos update by the way.

      I would maybe lookout for any ‘trolls’ perhaps coming out of the woodwork here too, to try to throw the cat amongst the pigeons. (mentioned here, just in case).👹

        Other than the music hicuo I ran into (that a system reboot seems to have fixed) it has been a rock. Not only have I not experienced a sub loss, I am also getting Dolby Atmos everytime I should, even when skipping between services. It's a happy day. Beers on me.

          So far so good. Going to keep testing this week.

            I really wish they would tell us what they fixed/changed after all of this...with as big of a head ache as this has caused and the amount of time I've seen some of you soend on this, I am extremely curious what it ended up being.
