one SL’s in surround set up.. right louder than left?!

Hi @marko2 , thank you for reaching us out and welcome to the Sonos Community. I appreciate your detailed post describing the issue and all your effort in checking for the resolution. Let me help you with this.

First, I'd like to ask a few questions and will give some suggestions on what you can follow.

1. Is the surround audio in full stereo?
2. Did increasing the volume of the surrounds on the Sonos app make any difference?
3. Have you tried removing and re-adding the surround? Did it fix the issue?

If you can submit a diagnostic report for us to check. Just include the confirmation number in your response so that we can look up the information.

If you have any questions about this. We and the community are always here to help.

Hi. 

Yes, surround is in Full stereo. 
The problem is the same with: stereo, Dolby digital, Atmos, 5.1 etc.…

BUT - it is fixed when I switch off trueplay  

Increasing the volume just turns both speakers up - but the right one is always louder regardless of the surround volume. 
 

I have completely removed the whole system twice including the arc and sub. 
I did factory resets on all speakers, and the reinstalled them again  

Here is latest diagnostic number: 1600946490

I strongly believe this is a software issue, I have friend with exactly the same problem and there are numerous forums online with people saying exactly the same… always the right surround speaker being noticeable louder. 
 

So this is obviously not just me. 
 

Please help to rectify this ASAP,  As an £1800 surround set-up should perform correctly in my opinio n

For info. Speaker surround positions. 
And yes I know the wires look a mess. 
that arch is getting bricked up next week and cables all getting covered then! 

Hi @marko2 , thank you for your response and for submitting the diagnostic. Let me help you with this.

Upon checking the diagnostic, Trueplay is currently disabled in your home theater set up. Trueplay measures how sound reflects off walls, furnishings, and other surfaces in a room, then fine-tunes your Sonos speaker to make sure it sounds great no matter where you've placed it.

There are some scenarios where Trueplay tuning may result in an undesired change to the sound of your Sonos speaker. Sound bounces on all hard surfaces in the room which have an impact on how the sound travel and affects the audio experience.

If you prefer the way your Sonos speaker sounded before tuning with Trueplay, you can disable Trueplay in the Sonos app. After the arch has been bricked up, tune your Sonos speakers again with Trueplay and see if there's an improvement.

We can wait for suggestions and feedback from our Sonos community members, they might provide their own opinion about this.

Please keep us posted.

Hi,

trueplay is off due to the dreadful surround sound speaker balance!

Also - I much prefer the EQ after trueplay tuning, but cannot live with the surround speaker imbalance. 

I have the same problem. Better sound with trueplay and want to use that but the surround sound is awful with that much difference on speakers that is just 50-60cm from my head. This was not a problem when I had the Playbar. I measure the difference it and it is about 2-4DB higher on the right speaker.

And yes I have tried it all. Reset, disconnecting, recalibrating TruePlay, with optical cable with HDMI. Nothing works. Everything I watch sounds like everything comes from the back right even when the car comes from the left.

Please find a fix for this quick.

I use Arc, sub and 2xPlay1.
