Trueplay brings stereo pair out of balance

I have tried to update several times and the message reads ’Update Problem’ ‘Try Again’ etc. 

Interestingly, ‘Trueplay’ is greyed out under ‘Sound’ in the app  

I wonder could one of the YouTube experts help. 
For example, ‘Smart Home Sounds’ really seem to know their stuff. It’s hard to know what to do at this stage. 

Updated system earlier and issue is still there!

A thought... 

Does trueplay break if you calibrate a speaker as a single one and then connect as pair? My thought was if it would be possible to go around the problem by calibrating each speaker in place and then pair them as stereo. 

Yes, Trueplay settings are wiped out when speakers are stereo paired/unpaired. My thoughts are to factory reset just one speaker only and try these things again and if that fails, to then reset the other one and see if that sorts it.

Obviously do not factory reset both at the same time, as otherwise you may lose the Sonos system/household if they are your only speakers, but doing each one individually and setting it up again before then doing the other, might be worth considering. (entirely at your own risk and maybe as a ‘last resort’).

Think of it this way…TruePlay is set up for a ‘room’ not an individual speaker. When you change that ‘room’, the TruePlay goes away. 

Yes, I like your idea better ;)

And I ‘think’ that’s the way the auto TruePlay speakers work, at the speaker level, rather than the room level…but I don’t have pairs to test that theory, either.

Updated to latest software. Removed both fives and the sub. Added them again. Ran trueplay…
 

Still the same issue as before. Right speaker sounds bad and is not ‘trueplayed’. Left speaker is all good. 
 

Come on Sonos this is not good enough. 

Have just had the exact same problem. Trueplay tuned my Pair of Play:5 2nd Gen and found balance had shifted significantly left. Dependent on song anywhere between 4-9 points right on the slider was needed to re-centre. Found the similar issue with only the left speaker being changed. The right speaker remained unchanged, with the Left Speaker being given a massive bump in Hi Freq performance. Did the tuning on my iPhone 12 Pro Max, so unsure what the issue is. Might try again tomorrow, but interesting to see others are having the same issue. It’s a shame as the quality upscale in the speakers (even if it was only the left channel) was massive, however as soon as I shifted the balance to a value where it sounded centred, most of the benefit had gone

New system update available, let’s see if that will help 🤞🏼

😬🤞

Update: problem solved!!

both play 5’s sound the same after Trueplay tuning
