Same problem with my Move2. Tried to “chat” with Support and got nowhere. Just started happening yesterday, I was able to adjust EQ and TruePlay before then. 

Hi @Angel24 and @T-Bone Tony,

I’ve had a look in our internal documentation and this does seem to be something we’re aware of. I’ve been told that we’re investigating the issue and do not currently have an ETA on when this will be fixed. If I hear anything regarding this I’ll update this thread.

The only workaround is to try with a different controller, so if you haven’t done that, then try adjusting the EQ settings another phone or a computer if you have one available.

I hope this helps!

Here I am doing my own tests with my Era 100 the day after having it disconnected all night along with the iPad air4 and the next day everything was working again. 
1- I started my test today and I started doing Trueplay Quick tune from my iPad air4 and after doing it the EQ no longer worked nor the loudness could be turned off and no changes are saved when exiting the option, but if I go to my Android phone everything works from the application.

2- I started to restart the iPad air4 and disconnected the Era 100 to see if it was fixed and unfortunately the problem still continues.

3- The problem seems to be in the Sonos application for Apple in my case iPadOS 17.6.1, because with Android the problem has not appeared and after doing the quick tune everything apparently works fine with Android.

Surely if I leave the speaker unplugged all night and the iPad off again tomorrow, the EQ will work again from the Sonos app for iPad. It is an error that must be corrected and I hope that Sonos will better deal with these updates that are causing problems for users and damaging the brand's reputation.

I’m seriously considering getting rid of my Sonos Move 2 and moving on to another manufacturer. I can’t believe Sonos is unable to fix problems with the app. For the premium price I paid for a top quality speaker, I don’t think I’m getting my money’s worth.

 I think TruePlay for portable speakers like the Move or Roam is dynamic so if you move those speakers they listen and adjust to their new environment.  If that is the case EQ adjustments would be unnecessary.  If you don’t like the results using TruePlay turn it OFF then maybe EQ would work.  Have not tried that.  The only thing I do is turn Loudness ON when I’m outside.

Can’t turn off True Play or Loudness. 

 Is Trueplay & EQ not showing?  Is Trueplay & EQ grayed out?  Settings (gear icon) - Tap on a speaker / Sonos Room - Scroll down to Trueplay & EQ.  Is the Trueplay & Loudness switch not moving to the ON - OFF positions?  Do the settings move but then pop back to where they were? 
 

 Sounds like the settings are not making their way to the speaker.  Some have suggested logging out of the app and then back in.  Do at your own risk!

The new update Sonos app S2 80.09.05 apparently I fixed the EQ crash after doing Trueplay quick tune from my iPad 4. I already did the tests and it seems to be in order.

Any updates, Jamie A? Seems incredible that this hasn’t been fixed as EQ is pretty central to listening to music. Can this be prioritized?
 

Not sure I would have bought this system if I knew how buggy it was. 

Hi @P2carter,

I still don’t have any ETA to share, though it does seem like a fix is in the works.

For now, I’d recommend keeping an eye on our release notes page for updates, keeping your system up to date, and using the workaround of a different controller.

Angel24, I tried to reply to your two other posts but they were closed for commenting. There is an inexpensive (less than a Sonos-branded one would likely be, anyway) microphone you could consider for Trueplay and it worked well for me. On Amazon, search for Dayton Audio iMM-6C Calibrated Measurement USB-C Microphone. It works on Android and iOS and for many other purposes, too.

@DavidOhio To what would you connect this microphone? As far as I know Sonos does not work with external microphones? Can you tell us how you have done this?

@106rallye The Trueplay calibration is normally accomplished using the microphone on your phone (I have an iPhone) and waving your arm in the air as you circle the room. It can be affected by a case on your phone or dirt/other matter in front of the microphone. The iMM-6C microphone plugs right into the USB-C port on the phone (it works with Androids, too, and there is another version that has a Lightning connector) and because it sticks out away from the phone it isn’t affected by a case - and it’s also designed and meant for measurements, not just carrying voices on a phone call. I’ve had better luck with it for room correction measurements for other audio products, too.
