Sonos Arc with TCL Series 6 no Atmos

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.

    Hi, Your posts helps! I have a TCL 75R615 and I am waiting on Sonos ARC that I ordered. Since the TV supports Dolby digital plan and has an ARC port, I was hoping to get Lossy Atmos sound output via all the TV's native apps. Are there any other other findings? Do you think app Roku updates of Netflix and Amazon Prime Video will enable Atmos output from those Apps as well? I also have an Apple TV 4K and wondering it the Apple TV's Netflix or Amazon app + TCL 75R615 will output Atmos on Sonos ARC? Overall do you think Sonos Arc is worth buying with TCL 75R615 ?

    Hi, 

    I have the same issue - no atmos on arc with Tcl tv and apple tv. The source is Netflix. Tcl can process DD+ and I can see DD+ in sonos app. Am I right that this the issue with appleTV? If I connect nvidia atmos is working?

     

    Thanks

    Do you have an Apple TV 4K? Do you have a premium subscription on Netflix? Have you double checked your Apple TV’s audio settings?

    Yes I have premium ultra HD. However in Netflix app I even can not see dolby atmos symbol when I browse movies. There is only 5.1 symbol. In apple tv setting it offers only stereo or dolby digital 5.1 there is nothing more in sound option.

    On your Apple TV 4K, go to Settings > Video and Audio and select Audio Format. Under Immersive Audio, check that Dolby Atmos is on.

    Apple tv is 4k for 100%. I think that tv is not able pass atmos, which is really weird because it can pass DD+. As far as I know netflix uses lossy atmos which is carried by DD+. So I thought that every tv with hdmi arc which can procces DD+ is also cable to pass atmos from netflix. Which obviously is not true

    Just because a TV can pass through DD+ doesn’t necessarily mean it can pass through Dolby Atmos. What is the specific model of your TV?
