Trueplay brings stereo pair out of balance

Were are you located? Strange they told me it was a known issue, and those you spoke to wasn’t aware of it. I have turned trueplay off and just adjusted the equaliser. Not optimal, but it have to do for now. 

I’m in GB. 

I have the same problem with my 2 sonos five. I disabled trueplay while waiting for a fix.

I’ve the same issue since 14.18 for a pair of ones (with mini-sub) and a pair of fives. 
 

One way did help, and that was to factory reset the speakers, log out of the sonos app and join them into a new network group - though it only worked with the fives and not the ones. And since updating to 14.20, the fives have reverted back to being biased on the left. 

I’d managed to escalate the issue with Sonos and was informed it’s a known issue which they’re looking into. Till then was advised to just turn trueplay off, which i have as even just changing the balancing is insufficient as there’s disparity between treble on them. 

Sonos claim - “At this point, this is an apple issue since sonos only gets then sound profile that the iphone sends"

But this doesn't make much sense to me as to why it’s an apple issue, plus I’ve tried with an ipad, iphone 12 & iphone 14 all running different OS versions. 

At one point I’ll get round to replying to their email and questioning this. 

Having the same issue. The speakers sound terrible using Trueplay. I’ve just posted having not seen this. 

The best answer is Not an Answer.  This issue occurs ALL the time.  Here is my experience… and a diagnostic.

Set Up.

Two Play 5’s Gen 2 and Sub Gen 2 in my garden room (aka Cabin), which is 3m x 3m.  Speakers at the front corners, sofa at the back with little in the way to affect sound.

If I perform a Trueplay tune up the Right hand channel loses all its treble and goes quiet.  The Left hand channel is fine.  Turn off Trueplay and both channels are fine but the bass is booming and the sub almost unusable, which is why Trueplay was so good before and the room sounded excellent.  The set up use to sound great until the 14.18 update.

What have I tried…

• Factory reset all three devices
• Swapped over the Left and Right speakers
• Retuned with a different device
• Stood on one leg
• Faced with back to speakers (in case I had a blocked ear!!)

Nothing works, it still sounds terrible with Trueplay on and the Right channel is all muffled.

I was about to send one speaker for repair as it was as if the tweeters had failed.  But factory reset and swapping them over in the room had the same effect after Trueplay… the right hand channel lost all treble.  And they sounded balanced with Trueplay off.

(this despite swapping the physical speakers over)

I am SO glad to see this post and know I am not the only one and am not going mad.  This is the second issue this year (the Move issues were the first) where an update has affected my Sonos experience, not for days but months!

I used to be puzzled at those who did not update as soon as a new version was released.  Now once this issue is fixed I will turn off updates until an all clear is given.  Sonos acceptance testing and QA is not working.

Just came here to say I’m experiencing the same thing with a pair of Fives - Trueplay messes up and applies to the left speaker only. 

Thank you. I am hoping this months update helps, however expect it will be another couple of months.

Very disappointed as this is the second time an update has ruined my Sonos experience. Some QA is lacking in these releases. 

I also faced such a problem. And I was ready to buy other speakers because I thought my Play 5 was broken. I see that the problem appeared 2 months ago, and it is still not solved. I am very disappointed.

I have the same issue. Ran trueplay twice, left speaker gets all the volume/clarity and right is muffled.  It’s fixed when turning off trueplay.

i also turned trueplay back on, but changed the balance to +15 right and now it seems even.  Stupid fix if you ask me, but it works until the next update I suppose?
