My Sonos system is setup in every room and also connected to the TV, sometimes it's blasting music non stop, other times it's playing as the TV sound bar. I notice that between acting as the TV bar and then playing music that the crossfade option turns itself off?! 

All of my playlists are set as alarms. Beyond changing up the playlists every one in a while, I have zero need to be in the Sonos app. And yet I find myself having to jump in to re enable crossfade.

I note this issue has been floating around in the forum's since 2012. What's the go? Am I missing a key step or is something so simple and saving my preferences being overlooked?
