When i use spotify to play back music through my sonos system, if I adjust the music volume in the spotify app, one of my room volumes increases much greater than the volume in the other rooms. This happens even if if level all the speaker volumes in the sonos app and then go back to the spotify app. Same thing happens, I press the volume up in the spotify app and the speak in my lounge get much louder than the one in my bedroom or dining room. If I go back to the sonos app, the volume levels for the individual rooms in the group are staggered again and not uniform as they were when I set them in the sonos app before going back to the spotify app.
Please can someone offer some suggestions?
I've tried turning off the speaker touch controls and the volume levelling is set to 100% for all rooms so there no restriction on the speakers. All 3 speakers are Sonos One speakers.
Thanks for any help and advice.
