Comment 10 for bug 237975

Tom : any solution yet to enable the preview of audio file is welcome.
Just because people misused it or activate it randomly and causing trouble for them is not an argument to simply drop it .
when Unity came, Ubuntu dev have still provide a way to have the old Shell as well as Gnome-shell , the same thing should be done here. disable but provide a way to activate it again when a user want it. deleting this option is not the best way.
