Yesterday the Room I was playing to was at an extremely loud volume. Fortunately I had Volume Limit set low enough to avoid speaker damage. The solution was to turn OFF Live Activities in the app and on the controller device, in this case IOS. It's too easy for me to accidentally press down on the volume up button when I'm grabbing the iPhone.
In the app I went to Account-App Preferences-Live Activity. Turned it OFF. This alone does not necessarily disable side button volume control on the iPhone. I had to also go to iPhone Settings-Apps-Sonos-Live Activities-Allow Live Activities turned that OFF.
Update: Airplay is still connecting to Sonos. Working on disabling this.
