Sonos Arc not showing Atmos in app, not sure if I am getting Atmos (Vizio P65-F1 w. 4k fire stick)

Hi All,

I have my Firestick 4k plugged into HDMI 4 and my Sonos Arc into HDMI 1 (ARC channel).

I set my sound settings on the Vizio p65 TV to bitstream (but tried auto as well).

Sound settings on Firestick is set to “Always DD+”

I tried several shows on both Netflix and Amazon Video with no luck in getting the Sonos S2 app to show the Dolby Atmos logo in the now playing screen.

On the P65 (TV) remote, I can press the “Info” button, and it shows I am getting Dolby audio, but I suspect it is not Atmos.

I’ve tried Jack Ryan season 3 ep 8, I tried Better Call Saul Season 4, Baby Driver, and a few others.

Is the S2 app glitchy? I tried it on both an Android phone and an Iphone. Am I really not getting Atmos? Where do you think I am going wrong?

Yea, the AppleTV4K has issues sending Atmos in a way that the Sonos arc can pick up. thats why the Arcana was made. From what I can gather (eg my interpretation) is that because the Sonos Arc doesn't support LPCM the ATV4K cant send it audio. Having LPCM would fix the problem and supposedly they are working on it though no official word. It’s a decent sized premium, market to leave ATV4K out in the cold. Subreddits for Sonos and Vizio both have a lot of discussion here.

Veryrealperson- wish I could help more - I dont think the issue with the HDMI port. I think HDMI1 -4 are all the same (except 1 is Arc) and HDMI5 is different to optimize for gaming lag. You probably wont notice much of a difference (but who knows with Vizio). I’d try using VUDU since across the board that seems to be the most consistent. Also, I’m attaching the screenshots of what your S2 App will show you when you have Atmos.

You’re probably not doing anything wrong. Your TV may just not be passing Atmos correctly.

Try the TV’s internal apps to see if they work with Atmos. If you can get THEM working, then you’ll know the TV’s settings are (as) right (as you can get them). I would set to Auto audio output on your Vizio as this has worked for me for internal apps.

as for the Fire stick, that’s a good question. Either the TV isn’t passing Atmos through correctly or you’ve got a setting wrong on your stick. I don’t know about those so someone else will need to jump in here.

good luck!

Thanks for the quick reply. Good idea to check the internal app, and I can report that Netflix on the internal Vizio smart TV app also does not show the Atmos logo in the S2 app. Tried it with Better Call Saul Season 4 ep 5.

Worth checking - make sure you’ve got an Atmos compatible Netflix plan?

I spoke with Vizio about my P75-F1, and they confirmed that the HDMI ports are incapable of passing anything more that Dolby Digital. Absolutely no Dolby Digital Plus.

Yes, I have the Atmos plan, should have mentioned that in the initial post sorry.

I am not too sure this is true, not sure what is making some users showing success in getting DD+ to work

I have a P65-F1 as well.

When Atmos is playing and you hit info - it will definitely say “Now Playing Dolby Atmos” with the Atmos Logo. You can also go to Menu, Systems Information and under Audio Type and Audio Type Out it will Show “Dolby Atmos- DD+”.

Your suspicion is correct - it it’s not Atmos, it just shows “Dolby Audio”

So do you get Atmos logo on those screens?

When I go to System Info (Playing John Wick 3 on Prime in Canada if that makes any difference...) it shows Audio IN DD+. There is no line item for even “Audio type out”

Any one know whats going on?

I don’t think you’re going to see Dolby Atmos on the system info screenshot you posted. Atmos is a format within DD+ (and TrueHD), not a separate codec. Sonos decided they would display the Atmos logo on the room tab (middle one that looks like an equalizer. click on living room so it’s the full display, not showing your other rooms. If you’re getting atmos you’ll see it there.

It’s complicated. For example on Netflix, both “6 Underground” and “Dark” show the Atmos badge on the title card. However, while 6 Underground will actually play Atmos as reported by both the TV and the S2 app, Dark wont (so, title card shows atmos, TV adn S2 app both show DD+). Note: this is using the Shield.

The TV and the S2 app are always aligned in what is being passed to the soundbar. However there is no consistency in the apps themselves. I’ve never see nothing appear in the Audio Type Out, usually there is something there, so that’s pretty weird. I’ll take some pics / screenshots tonight so you can see what it looks like for reference.

I’ll check the episode you mentioned and see what I can find. Im in the US, so not sure if that will impact things.

Some other testing notes:

When using the built in apps from Smartcast, I can’t seem to get Atmos on Netflix. Based on some fiddling with the Shield, the app itself changes based on the system settings. i.e. if I turn off Atmos supported codecs on the shield, Netflix throws an error, restarts the app and doesn’t show the atmos badged. Turn on the coded support and Netflix crashes, restarts and Atmos appears again - so it seems to be reading the system when it loads, then determines whether or not to show Atmos options (does the same for DolbyVision, etc).

Side note

It looks like there are a LOT of problems with this stuff in general. LG users have a hard time with getting Atmos passed through, Sony has some hiccups - everything depends on the model. ATV4K users have issues too. Its all confusing since $K UHD HRD10 T with Dolby Vision and Atmos doesn't mean that it accepts/passes through Atmos from other devices. This is why a company called HDFury is putting out a decve called the Arcana - but then you’re another $200 (USD) in.
