Merged all the threads in here.
I've ask Grant about this and he said that you should not need to use it for it to work but only the most powerful one does. So if you have more than one object, you need to disable the rest.
In my own experience it sometimes takes a moment to kick in too.
An update to my original bug report.
Since I was in a household with the Rock of Ages stereo I thought I would check to see if maybe the emotional aura was working after the 2/4/16 patch. It wasn't but as I was getting ready to disable it I noticed the little tool tip indicated the object had to be viewed for the moodlet to work.
I don't have an option to "view" a stereo. Am I supposed to? If not, I would say that accounts for the inability of the object to emit its emotional aura and only EA can fix that.
