Arc - Vizio and Atmos

Understood. My comments were about the ability to pass Dolby Digital Plus from an HDMI input to the HDMI ARC output. Vizio says it isn’t possible on their TVs. 

According to the Sonos App, it is - at least for the E70-F3. Watching Marvel’s Agents of S.H.I.E.L.D on Netflix right now via Apple TV 4K and this is what the app is showing as the audio signal it’s receiving: 

 

Can you post your settings, cable models, etc for us? Right now, I can’t get my Apple TV 4K to pass DD+ through my M658-G1. Vizio support says it won’t, but it looks like some models of Vizio can. Curious as to why some with Arc can and others with Arc can’t. 

If I use the built in Disney Plus app on the Vizio Smart TV dashboard, it works...wickedly frustrating

I have Apple TV 4K + Sonos Ark+ Vizio P55-F1

While using the ATV 4k i only get Dolby Digital 5.1.  However when using native Netflix app i get Dolby Digital Plus 5.1

I have few questions?

1. Can i get DD Plus 5.1 using ATV 4K?
2. Do i need “8K” cable? does it matter?
3. Any way to get atmos without chnaging the TV?  I feel like an idiot spending $1,900 on Sonos Arc + Sub to not get Atmos.

Here are some answers: 

1. No, and especially not with that model TV
2. Cables Matter, but no you don’t need an 8k cable. However, Cable Matters has a relatively inexpensive 8k HDMI from Amazon that’ll do the trick and carries 48gbps, more than enough for your data stream
3. yes, but I’d recommend then considering something other than Sonos at that point. That TV won’t pass atmos to the Sonos, it’s falsely advertised by Vizio. You’d have to take the Apple TV into a receiver first, like a Denon AVR or Sony AVR, and then video out to the TV and optical audio out to the Sonos. It would be a nightmare of a setup, considering at that point you might as well just go traditional surround speaker setup. There are a few third party devices that’ll help...you’ll quickly find they all limit your Sonos to one input device, you won’t be able to use anything with it but the Apple TV. 

Thank you,

I cannot house full fledged receivers with my setup hence opted for Sonos.   Are there newer TV which will work with Dolby Atmos  for Apple tv 4k and Sonos ark?

There are! 
I’d personally look at the Sony 950 series. They pass through Atmos without issue. 

Any TV should appropriately pass through the correct signal to the Sonos Arc (not Ark)  provided it has eARC. Currently, I’m aware that Samsung has issues with their software on the Frame TV, but all other TVs with eARC seem to be working fine. 

You’re correct. However, start with “any tv with eARC”, buried the lede a bit there. Most TVs do NOT have eARC, but a lot of late 2019 and 2020 models do. That is the key, and almost all Sony models above the 800 series do now. Vizio’s new models do as well, older models do not. 

I can confirm older Vizios (last year’s) do not… I own one, to my frustration. Looking forward to hooking up an HDFury Arcana. 

I also own one, an M658-G1, and it killed me to find out that it advertises atmos…...but only for built in apps. Should’ve guessed eARC would be absolutely necessary. 
 

Switched my setup a bit, and happily enjoying atmos in that room...alas without Sonos :-( 

OP- look into the HDfury Arcana. It’ll do the trick, but beware it’s a single device trick without a switch. 

Ok. So if i buy a TV with eARC, does it mean I don’t need to worry about Dolby Atmos issues?  or are there any more gotchas
