Lost "Default Beep"

[Herb Kelsey]

I had to do a full restore of my system - operator error,
don't ask - and when it came back all seems fine except
there is no "default beep" in the sounds table. All the
other 'stuff' is there but no default beep. Now my
computer flashes at me when a default occurs but there is
no sound associated with it.

I find no option to add or remove sounds so I don't know
where it went.

Ideas?
