Why did the new Playbase not integrate Dolby Atmos?

I think you missed some key words...."to gauge interest in"....

apparently there is a survey being pushed out for Atmos:

That would be using software to emulate and no different from the bars that give virtual surround. While it sounds better than stereo it is nowhere near the real thing. Sonos have themselves stated that they wouldn’t do it just for the sake of adding it, they would want to do it right. Even the most expensive sound bars that have Atmos, plus the upfiring speakers, are heavily reliant on the room it’s placed in and how it can bounce the sound. You really need in ceiling speakers to have true Atmos.
I disagree, a have Dolby Atmos built in to my phone (Razer), and it's mind blowing, the phone only has 2 front facing speakers so the amount of speakers is not a limitation.

The phone with its relatively puny speakers is able to to produce sound whereby it sounds like either a helicopter or an insect is actually behind your head or above or whatever.

I have only experienced Dolby Atmos on my phone (and the cinema but that's different) and it is the most incredible sound experience ever definitely the future of audio.

+1 from me for working out a way to support Dolby Atmos

Atmos doesn't even make sense in a soundbar, let alone a cheaper one like the beam. The ones that remotely have decent quality are quite expensive and are still not true Atmos. If one really wants that experience they're better off with a receiver based system
Oversimplifying: Prior to Dolby Atmos all that Dolby did over and above 2-channel stereo sound was to add additional channels.
Dolby Atmos is different. It's a paradigm-shift. Also it's not just a trend I'd think. Who knows, maybe we'll be able to stream Dolby Atmos audio tracks at some stage? Recordings of classical orchestras would certainly sound very different.
The Beam falling short on Atmos support is not encouraging. Missing out on paradigm-shifts can be deadly for vendors. Just think of Nokia and Blackberry.
Being relatively new to Sonos and having read this thread, I just hope Sonos will not miss the boat here.

About DolbyAtmos and SOnos

Sonos talks Dolby Atmos, DTS, sound quality and Beam soundbar
The new Beam speaker has an HDMI input so I am hoping that Dolby Atmos is going to be supported starting with the Beam.

There may be some hope yet

A question about the Beam posed to a Sonos rep recently, the reply mentioned that the Product Manager at Sonos loves Atmos and would like to see it implemented in future products but they had no further announcement to make at this time
Ryan, Netflix supports Dolby Atmos.

Hi Gwoodster,

Here's some details we've shared around Dolby and our decision around it.

Dolby Atmos is an attempt by Dolby to standardize cinema sound from production to theater exhibition to in-home distribution. More than just a codec, Atmos is an authoring language for cinema sound. In theory, Atmos allows a sound designer to specify the location of a specific sound in a 360 degree sphere and then render that sound ‘accurately’ whether a given room has 1 speaker or 64. You can think of Atmos like a ‘vector’ graphic format such as EPS which is a series of instructions for how to render an image vs classic Dolby Digital which is more like a GIF.

In the home context, Atmos is often described as a way to create a sphere of sound where certain sound effects appear to be located above the listeners. However, ‘ceiling sound’ is only one aspect of the Atmos format.

At Sonos, we are intrigued by the future applications of Atmos in the home context, however like most new codecs, Atmos is only as good as the content which is encoded and mastered for the format. Today, native Atmos content is very limited. Like DTS, most Atmos content is found on Blue-ray and Ultra HD Blu-ray physicals discs. Only a limited amount of streaming content from VUDU uses Atmos. As Sonos is focused on modern listeners who predominantly steam, we have decided not to support Atmos at this time. We will continue to monitor the state of home entertainment to determine if Atmos is a feature that will improve the experience for the majority of our owners.

Are you saying that the Sonos is using the 5 GHz wireless band? It only uses 2.4 GHz as far as I know.


It is using 5 Ghz for the speakers bonded in 5.1 home theatre.

Just wanted to comment on the point made a couple months ago that if Sonos can handle 32 speakers in a system, then they would be able to handle a 7.1.4 system, or whatever it is. I don't think that's a great comparison though, as the standard wholehouse setup is a net, meaning each unit passes the stereo signal on to others without the original source having to make the connection to all the units in the group itself. It also is done over 2.4 GHz and has a nice buffer. The Home Theatre setup is different in that the playbar unit has to send the right channel of sound to the right speaker by itself. It's not a net, it's more of a master slave situation. It also has to be done at 5 GHz with no real buffer in order to keep the audio in sync with the video. So in order for a new playbar to do dolby atmos , it's got to be able to send around maybe 5- 12 separate signals to all the speakers in the atmos group, with not much buffer to work with. A lot more difficult.

Not to mention, are there going to be that many customers that want to buy that many speakers and have the ability to plug them in where they need to go. I realize that a lot of the channels can be built in to the soundbar, but it's still quite a bit.

What does "true 5.1" mean?? The Playbar/bases already do that.

I cannot wait, I sold my playbar few years ago.i still love Sonos just been waiting for an update I hope this is it I'll gladly ditch my receiver setup and wires for an updated playbar that can do true 5.1 I don't even care about Atmos that would just be icing on the cake.

A little outdated comment in that we know an hdmi capable playbar is getting announced in June.
This is the reason I use the Sonos System ONLY for Music. I have a Receiver and wired speakers to get all the toys that Movie Media has to offer. I came to this site to see if I could use Sonos for everything and sadly I cannot. Only music, which is fine with me. I'll keep checking though to see what the future offers.
According to the information here: https://www.lifewire.com/digital-optical-connection-1846881

It is important to note that digital audio signals, such as 5.1/7.1 multi-channel PCM, Dolby Digital Plus, Dolby TrueHD, Dolby Atmos, DTS-HD Master Audio, DTS:X, and Auro 3D Audio cannot be transferred via Digital Optical connections - These formats require HDMI connections.

Which means that if indeed Sonos is looking at it, they're looking at a new device that has HDMI, and none of us who have PLAYBARs or PLAYBASEs will be able to play without a replacement device.

Sonos CEO told someone in September that they are actively looking into incorporating Atmos. There was a Reddit thread on it.
Just like 4K being few and far between, Atmos will soon be everywhere and the norm. All in time...
Writing here as someone looking to purchase a soundbar. Would dearly love to consider a sonos but i just don't see a new playbar being on the horizon, which is a real shame.

Looking at the new sony and LG bars announced with dolby atmos rather than waiting for sonos indefinitely.

Sonos is dead in the Home Theater waters if they don't announce something this week.
