Sonos Arc Ultra center channel too loud

I like that the dialog is very easy to hear without having to turn on any dialog adjustments. The problem is I barely hear the left and right channel audio. Background music is barely audible. I’ve tried it with both Trueplay turned on and off and there isn’t much improvement. I know the left/right channels are working because I hear music. Anyone else have this problem?

Hi @not_convinced & @mindthings 

Welcome to the Sonos Community!

Sorry to hear that you are not both entirely happy with your new purchases. I recommend you get in touch with our technical support team who have tools at their disposal that will allow them to give you advice specific to your Sonos system and what it reports - if there is an issue with the sound mix, it will need to be documented before it can be addressed.

I hope this helps.

I recently bought Arc ultra, pair of Era 300s and Sub Gen 4. 
 

im having the same issue as in the thread. The Centre channel is so loud and the rest of the sounds are barely noticeable. You can see the subtitle but you can’t hear the person talk unless the subject is in the middle. 
 

tried so many trouble shooting and no fixes. Hope a fix is released soon by Sonos.

Has anyone had any better luck on this topic? Or any support / response from the Sonos team on this? 

Unfortunately if anything my experience is getting worse, I’m having to continually adjust the volume on my Sonos for different scenes. 

Curious to know if any others on this thread have given up and purchased an alternative, and if so, what? I’m looking at cutting my losses and selling the Arc ultra and Sub 4, and buying a Samsung HW-Q990F all in one instead (given I’ve heard reports of issues using Eras as surrounds).

Submitting diagnostics and calling support is the only way to get issues like this on the priority fix list.

Huh. I use Era 100s in one room, Era 300s in another, as surrounds with zero issue on my Arcs. Wonder if what you’ve been hearing about is an actual issue with the Arc Ultra, or just people who don’t really understand how Sonos, interference, or networking works.

I have the same issue: the left and right channels are significantly quieter than the center channel. Please resolve this quickly.

Hi ​@Corry P, has there been any movement with a centre channel volume slider please?

It’s so hard to hear left and right ‘voices’ when people are on the left or right of the screen. Compared with the centre being around 8dB louder.

 

It means I have to constantly turn the volume up and down and it means the volume is always wrong.

 

Please can this be looked into?

Hi ​@Gavalar 

I have not heard anything, but that does not necessarily mean that nothing is happening - I believe such an adjustment would need extensive reprogramming/retraining of TruePlay Tuning, which would be no small task.

I will try to find out, but I really cannot promise that I will receive an answer.

Maybe Sonos should just start by fixing this bug, so the center is not twice the volume of the sides.
This makes the Arc Ultra sound really “weird”, and I find it very hard to believe that it’s intentional.

I have mine on medium level voice enhancement and in no way is the center channel “twice the volume of the sides” . . . not even close.  If I were you, I would try to see if anything upstream from the Arc Ultra is adding to the voice enhancement, such as the TV or a streaming device.

The difference is 7/8dB, so in relative terms, it’s around twice the volume.
