Sonos Arc with TCL Series 6 no Atmos

29 replies
7096 views

New Arc, Sub, One SL x 2 home theater surround connected to TCL Series 6. Signal to TV from Apple TV 4K, Arc connected to TV via HDMI/ARC port. TV set to autodetect - TV indicates that it is detecting DD+ signal. Playing content that should be Atmos (have tried atmos movies on iTunes, and also atmos content on netflix (streaming at ultra HD/autodetect). Should (I think) be sending Atmos signal to the Arc. however, cannot verify this. No Atmos logo in the “playing now” screen. When I go into the S2 app, “about my system” it indicates the signal is “Dolby Digital Plus 5.1”. Appreciate your thoughts / experience…. Apologize if I’m missing something obvious here. TY

Audio format offers only change format - on. New format - dolby digital 5.1 or stereo. Nothing else. I also tried to use new hdmi cable. Nothing changed.

Either your TV and Arc aren’t set up correctly, your TV isn’t capable of passing through Dolby Atmos, or your Apple TV isn’t an Apple TV 4K model.

You didn’t specify a model #, but there is a good table here:

If i read that table correctly, your TV can only passthrough DD 5.1 over ARC. Atmos will not work for you.

Thanks Controlav. Appreciate your response. I have the 65S425.

You are correct, does not have eARC and cannot pass Atmos through true HD.

However, my understanding (perhaps incorrect?) was that there Atmos data can also be passed through via DD+ on this TV via the ARC connection…? Lots of postings suggesting this to be the case, but I may be getting misinformation.

Given that the ATV 4K only has a single HDMI output, how might I configure this to get Atmos sound out through the HT system (if possible)? I only use the TV for video from the ATV box, no video coming through the roku system.

Thx!

Hi there, I’ve got the 75 TCL 615R, connected to the sonos arc, i get no dolby atmos from the tv’s netflix, prime and disney channels at all, cycled through all the audio codecs in the tv and get no atmos just dolby digital 5.1, but when i play any content from the tcl dolby app it gloriously show the very elusive dolby atmos on sonos app. i was planning to buy an apple tv 4k just to get that very elusive dolby atmos, but it seems that it wouldn’t work. I read that hdmi arc can output atmos through DD+ embedded with atmos but its not working, It’s very disappointing to invest on hi end gear that doesn’t deliver.

Quite a set-up you've got there, and was thinking that's the future of what my system would be. Had the TCL 615R way before the Sonos arc, and can't exchange the TV at this point. I'm hoping for a firmware update from TCL or from sonos that would make the Sonos arc Atmos work on our tv, and yes I read from a lot of sources that Sonos arc should be able to output lossy Atmos from DD+.

How's your setup so far any good news?

A follow up have you tried the "passthrough" on audio settings? Btw try playing any video from the Dolby channel in your tv and you will see the Dolby Atmos on your Sonos app, it just shows that TCL R6 to Sonos arc is capable of doing Atmos ...

So…

Have confirmed that TV can send Atmos signal to Sonos, as you suggested via Roku dolby channel app.

Have tried setting tcl setting to passthrough. Still no good. ATV (running current tvOS 13.4.6) doesn’t seem to be able to push Atmos to the Sonos system through the TV. Per everything I’ve read, should be sending lossy Atmos through DD+. In ATV A/V settings, audio format should have options for “immersive audio” and “Dolby Atmos” per the apple support site, but those options don’t exist, and the best I can get is DD+ 5.1… If anyone has made this work, would love to know how! Thanks.

Yes a good amount of LG tv owners have had luck with the ATV hdmi to LG hdmi arc to SONOS ARC , I assume you know that there was a decrease of bandwidth on streaming services due to the covid thing, so I tried to connect my Oppo BDP 130 to TCL , put in Superman vs Batman blueray disc with Atmos and nothing just DD+ 5.1 on the Sonos arc what a bummer . Still that elusive Dolby Atmos from a high end Atmos capable soundbar.

Finally Dolby Atmos on Netflix and Prime via NVIDIA SHIELD 2019 ! Basically plug and play, Dolby Atmos confirmed on Sonos app the only caveat is that Disney+ although displaying Dolby video and Atmos in the channel only outputs DD+ 5.1 on Sonos app, with the additional investment we ought to have Atmos on Disney and more ! 🤨

Finally I get Atmos on Disney+ on Nvidia shield , I just turned on the tv clicked on a starwars movie and bam! Sonos app confirms it's on Dolby Atmos DD+, no settings no tweaks it just worked . The Nvidia shield is fast , has games and upscales like a dream, additional expense but all worth it! Thanks and Godspeed everyone !
