I have a strange problem. In one room I have 2 sonos five in stereo. After trueplay is done, they are out of balance. I have to slide the balance 5 points to the right. If i toggle trueplay on off, it is very noticeable. with trueplay off balance is in center 
♂️ Anyway to fix this without using the balance control?

I have submitted diagnostic as has others and it is a known fault. Hope the next release may fix this.
Have you submitted a diagnostic, and called in to Sonos, so that they have hard data to look at?
Same problem here with a pair of Play5’s, after TruPlay the sound is terrible.
left speakers seams louder, but the real problem is that the left one is much clearer (more treble) the right one is much more muffled 😓
Same issue here with a stereo pair of Fives.
Glad I found this thread. Will be contacting Sonos support tomorrow to log the issue with them. Hopefully the more reports they get the quicker it will get fixed.
same here, brand new set of stereo Fives. with true play off left Five is slightly louder. with true play on eft Five is noticeably louder and treble happy while right Five is muffled. Sonos says they are unaware of the issue (USA) apparently have to call them later to escalate it. they initially claimed it was a network problem til they realized that my plethora of sonos products all connect and stream flawlessly. this is definitely a software issue that they need to work on
Looking forward to hearing how you get on. I will be following up too and will post findings. Just has to be software. Also, saw some similar incidents that were reported a couple of years ago on this forum.

I have the same issue with Sonos Five in stereo. If I unpair them, either one of them can be tuned with trueplay. But paired, only the left speaker
I have this issue too. Ones as rears with Arc and Sub Gen 3. Left rear often starts louder, however, if I toggle Trueplay on and off the issue is fixed, temporarily. It might play correctly for a couple of songs and then it will revert back. Even if I restart a song it will go bad again.
i only have the system a few days - typically, how long would such an issue take to resolve?

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.
It's unbelievable. After several factory resets, one of the speakers stopped connecting. Now the phone is trying to connect to the Sonos Play5 WiFi network, but an error appears and an offer to connect via the Internet cable. Is WiFi broken now?
Have you supplied this hard data to Sonos in a diagnostic, and contacted them about it? They never tell us whether they’re working on something, much less if they can reproduce it, but providing them the information from your various systems might help them track it down. For what it’s worth, I’m not experiencing this issue on my various speakers.
You could try Trueplay again, but stay more at your preferred seating position.
I have tried multiple times, with iphone 12 pro and my Ipad, but the results are always the same. Left speaker is louder then the right. Very annoying… If I turn off trueplay, they are back in balance 🤷🏻♂️
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?

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.
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.

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…
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.

Having the same issue. The speakers sound terrible using Trueplay. I’ve just posted having not seen this.
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.
I have the same problem with my 2 sonos five. I disabled trueplay while waiting for a fix.
I’m in GB.

I’ve was on the phone for nearly 2 hours and the person I spoke to had no idea. They spoke to a few other people too.
I’ve just separated my fives totally and then grouped them together and the sound from both is pretty much identical. So this would suggest a software issue.
it’s very frustrating though. Because it makes it sound like a speaker is faulty.
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’ve just finished on the phone with customer support. They ran numerous diagnostic checks and can’t find a issue?
They checked the speaker and said it’s working fine, I’m not sure what’s causing this.
Sonos are not aware of it, but I can find a few people saying the same thing on the community. Hopefully it’s a simple update to rectify and eventually not a problem with the actual speaker.
I have to send a video through email showing the difference in sound between each speaker in a stereo pair, so SONOS can have a look at it.
Strange, I was in contact with Sonos Norway and they said it was a known software issue 🤷🏻♂️🙈

I have now been in contact with Sonos. It was a known software issue, and they were working on it. So hopefully it will be fixed soon 🤗
