Hi Steve,
The Max2Play plugins are developed by us and usually have nothing to do with the Squeezebox Server plugins. I can ask our chief developer if he can add a fixed volume function. Which option in the Spotty plugin do you use to keep the volume at a certain value?
Edit: didn’t see your edit. I will still ask our developer if it is possible. However, I believe that you can hardly bypass Spotify’s standard settings.
