First things first. This is not a rant. This is an expalation of a problem, which reduces the experience in 3D audio a lot. For background: I'm a sound engineer and music producer and I don't wanna sound arrogant, but I know what I'm talking about. (I'm a really nice and funny guy :D)

So lets get to the problem then :D

NO I'M NOT TALKING ABOUT THE FRONT FACING DRIVER

for better understanding watch this VIDEO

This bug appeared the moment I switched the Arc with the Arc Ultra. Before I made the switch I was on the 16.1 app and firmware. So I don't know if the Ultra causes the problem or the app/firmware. Before the switch everything was running as it should.

So, since there is not much of a topic around this, I'm curious if I am still one of a few who have this bug or one of a few who noticed it.

I made this post in Reddit, but not everyone is on Reddit and the more people know, the faster Sonos can work on it. Reddit discussion

I didn't saw any review which mentioned it.
As you can see in the video, the rear driver is completly silenent when the Era 300's are paired with the Arc Ultra. Also Truplay isn't "sweeping" the driver either. (Timestamp 0:44)
So the mesurement isn't right.
First I thought it could be a feature instead of a bug, but it doens't fit the Dolby Atmos recommendations like this. You won't get sound from "behind" your seating position.
And I remember Sonos self promoted it how it should work, where the rear driver is playing.
 

DOLBY ATMOS LAYOUT

Sound from side driver/channel should boucing off your side walls, rear driver/channel bouncing off the back wall of your seating position and height channel obviosly bouncing off your ceiling. Thats why you should position them facing forward. At the moment you don't get the immersion that sound is coming from behind you, since the driver is silent.

I tested every setting, played the Dolby Atmos testfile (MKV KTrueHD Atmos] and MP4 PEAC3 + joc Atmos]) from different sources (TV Plex app, Nvidia Shield, from a USB through TV) Same result everytime.

If someone could test this behavior and can confirm this, it would be very nice. Sonos can't fix something they don't know and if most people doens't recognize doens't mean something isn't wrong.

Currently I'm running app version 80.12.04 (Android) and 80.12.03 (iPhone) and firmware version 81.1-58210.
If you don't have this problem, what version are you running?

And last but not least: IF this ever getting fixed, the experience with Arc Ultra and Era 300 will be much better! I love my Sonos products soundwise and Arc Ultra is sounding really good, but it could be much better.

Have a nice day

Something needs to happen. You don’t just cut off speakers and say that it was doing it wrong the whole time when no one even complained the 300’s were bad in any way, shape, or form.
 

It’s even more frustrating hearing the company who made the speakers describe the speaker itself exactly the way it supposed to play/function in those YouTube videos. 
 

lmao it’s like a “woops - we described our product completely wrong - our bad. Here’s the way it supposed to function a year and half later” 


 

The inner drivers did work, so it’s quite baffling that they were disabled recently.

As far as I am aware, the behaviour of these drivers has not been changed. I am currently seeking clarification on the behaviour of the inner drivers, however, as someone on the Audio team said the following on Reddit, which disagrees with the above quoted text in blue from my documentation:

 

Can we please be honest with eachother?

There was literally a video where one of sonos senior VPs was explaining how the rear channels were being output from the inner drivers of the Era 300s. And I say that there WAS a video because it was promptly taken down by Sonos as soon as it was posted in here. That was really scummy btw.

Let’s at least stop pretending all your customers are stupid


Hi ​@superlollo 

Can we please be honest with eachother?

Yes. The video is still here: https://www.sonos.com/en-us/sonos-live, but was taken down from the YouTube channel as part of a general clean up, as I understand it, along with other videos. I agree that the timing was lousy.

The statement made in the video agrees with the statement in print on the Reddit event, which I quoted above. It does seem like this is going win the contest over the information in my documentation - it was this that I was waiting for clarification over, and still am. Official documentation is official documentation, and I have to stick with it, which is why I - and others - have been seeking clarification over this apparent mistake. I apologise for any confusion or consternation caused as a result, but we are trying to rectify matters.

Please know that we are listening to the feedback you are all providing, we are presently investigating the reasons for the feedback, and I personally think it very likely at this point that changes will be made.

I hope this helps.

Thanks for your answer, I appreciate it. Currently the inner drivers are completely disabled, it’s not like the volume is only lower. If it actually is lower, it is 95% lower, you can’t hear anything unless you put your ear right next to it (touching it). At that point you might as well turn it off.

I’m sure it wasn’t like that a couple of months ago, you could clearly hear it. Even in trueplay configuration, both quick and advanced, the inner drivers don’t emit any sound at all.

 

Having some sort of setup in the app where you can specify your surround placement (corner, close to a wall, no wall) would be extremely beneficial. My B&O speakers have such a setup and it’s not like B&O is a huge software company or anything. Even better, some separate volume sliders for left/right surrounds.

 

If Sonos is afraid that the user will screw it up, just add an “advanced” mode in the app that enables those functions only for those that want to use it. My router has something similar, when you login you can only see some very basic config options, but then there’s the “expert” menu which allows you to do all sort of stuff at your own risk.


Hi ​@superlollo 

You have made 3 good points there, and I added them all to the document that will be passed to the people who decide such things. Thank you.

Maybe it needs an extra button too, to revert to Sonos’ Standard Configuration. Make it a two-click process: “Reverting to Standard Configuration will erase all user customisation settings for this room. Are you sure you wish to proceed?”

 


I feel like such a fool, I went through 3 months of waiting for the fix for the og Arc and sub problem and forgave and forgot too easily, I foolishly went onto to purchase the Era 300’s when they came out and paired with the Arc (the inward drivers worked as then described for rear sound, up firing driver worked as they should, you would only hear them fire when sounds were supposed to be from above) 

But then even more stupidly I laid out more cash for the Arc Ultra, so to now being totally gaslit by Sonos by removing all the original information and videos of how the Era 300’s work and sticking your heals in and saying this was all by design is utter garbage, who on earth would mix hight channel sound with rear channel sound and fire it all to the ceiling ? It is beyond belief, my guess this is in an attempt to kill anymore bad press after the latest backlash over the app but you have done completely the opposite I'm afraid.

I was mulling the idea of replacing my hi-fi amp to Sonos before this but not a cat's chance in hell now.
