I don't think obj2 is evaluated at the point of mouseover, but that 
would not stop obj2 being a graphics object. To get an immediate sound 
(as opposed to a widget that can play a sound) you need EmitSound, which 
needs to execute when it is displayed, which you can get using Dynamic:

Tooltip[fred,
  Dynamic[EmitSound[
    Sound[{SoundNote["c5", 0.3], SoundNote["g4", 0.3]}]]; ""]]
