Sonos ARC and SAMSUNG QLED 2019 with one connect (q950r, q90r)

Basically, Atmos is an audio format that can be delivered under two different codecs, Dolby Digital Plus and Dolby True HD.  DD+ is lossy and is usually found in streaming sources, which would be your TVs smart apps, AppleTV (which also does Dolby MAT for it’s Apple apps to complicate things) and your PS5.  DD+ can be transmitted by ARC, so your TV should be passing through these sources  Whether it does or not is a question for the TV manufacturer.   TrueHD, lossless,  is usually on blu ray disks, so that’s your BD player or discs you play through PS5.  TrueHD requires eARC, so you won’t be able to get atmos from those sources.

For me, I rarely watch discs anymore as streaming works great.  When I do, it’s usually older DVDs and BDs that are not in Atmos anyway.  I don’t know that  I’m missing much sound quality between DD+ and TrueHD.

Hello, thank you very much for your answer. 

The only interest for me for the PS5 is games + 4K UHD blu ray, not streaming services as they are already in smart tv.. I hope games and discs can output DD+…

Same question for nvidia shield actually 

I don’t think any discs are in DD+, TrueHD only.  PS5 games, I have no idea.  Doing a quick search and it seems still to be unknown whether the PS5 will even support Atmos.

I know little about nvidia, someone else should address that.

Hello, sonos arc available tomorrow, and still no answer...I won’t risk anything at this price so it may be new sony atmos bar instead probably, as it is equipped with 2 hdmi it’s more safe. 

Too bad sonos is so quiet, this question is asked on multpile websites and samsung tvs owners are in doubts (also because of all beams problems on these tvs)

I’m sorry if my tones “sounds” annoyed or angry, it is not. And thank you for your answers of course.

Actually, I though the first answer was not sure about 4K discs & PS5, so I was waiting for an official answer (or from a samsung tv owner test),  

So if answer is no atmos from 4K blu ray discs because they are trueHD, then this bar is not for me (and believe me I am soooo sad...). And as you mentionned, as the PS5 wont come out until several months, I prefer to get a bar where LPCM or atmos trueHD sources can be handled to avoid having stereo sound on a 900€ soudbar!

@Rom7475 Apologies accepted. Maybe I read your comments wrong - I am not an native English speaker.

To you question: I am not sure any soundbar will play Atmos since your TV does not put this through to the soundbar.

I have the arc and samsung d900r and can confirm dolby atmos works with netflix (all be it quite buggy to get going)which passes atmos via DD+ but will not pass it through any other native apps, apple tv or any external devices such as games consoles or UHD players. Whilst I think a second HDMI port would have been sensible, I personally blame samsung for failing to install earc on their flagship tvs and for their poor handling of codecs in general. 

Thank you so much for your (unfortunate!) answer.

I feared that would be the case. 

Please could you explain “all be it quite buggy to get going”

And  also “will not pass it through any other native apps” does it mean disney+ , amazon wont pass DD+? 

Unless your TV has eARC it will not be able to pass anything higher than DD+ to the Arc, although it sounds from a previous post that it won’t even pass DD+ via the build in apps which is a. It strange for a relatively new high end TV. Maybe Samsung just need to update the build in apps.
