This is a known missing feature.
(The RTL source only uses MessageBeep(0) call)

   You are very welcome to propose a
patch for adding support for this feautre, but
don't forget tat there are still 
(even if it becomes very rare)
win32 systems that don't have any sound systems
Moreover, I suspect that 
that code will need to be different for win9X/Me
and for winNT/2000/XP....
