Hi Axel,

I think it can not be done.

Tooltip is an ordinary function, its arguments are evaluated before 

beeing fed to Tooltips. Further, if you play a sound (e,g, using Emit) 

nothing (Null) is returned. Therefore, obj2 must not be evaluated during 

evaluation of Tooltip, but only later when the Tooltip is used. I do not 

see how this could be achieved.
