If I limit the max. volume in the Sonos app for the Roam, like setting 50 %, the system sounds for on, off and bluetooh occurs still at 100 %. They should also be synced to 50 % percent.

So if I set the Roam to max volume pushing the buttons on the Roam. I hear the music at 50 % and the system sounds are much to loud at 100 %.
 

Any other user with the same issue or a solution?
