You may want to try a factory reset too. Not normally recommended but you’ve nothing to lose.
Sonos Move
- Take Move off the charging base.
- Press and hold the power button on the back of your Move for at least 5 seconds to power it off. You will hear a chime and the status LED on the top will turn off.
- While holding the Join button, press and release the power button.
- If your Move’s battery is not charged and won’t power on, you can place it on the charging base while holding the Join button instead.
- Continue holding the Join button until the light on top flashes orange and white.
- The light will flash green when the process is complete and your Sonos Move is ready to be set up.
You can add your Move back to your system by following the steps in our Set up your Sonos Move article
So after a reboot the situation didn’t changed. At the end the solution was in the name: MOVE! I took the move with me to my father house to let him hear the problem i had and boom: after few seconds the audio leveled itself. Now i can still hear that bass has been “boosted” a bit but i like it now better than before the update.
I tought the auto trueplay would continuously adjust the audio but probably an input from the accelerometer has triggered a “full retune”.
Thank you all for the suggestion, luckily that was an easy fix. Yesterday i was very mad!
