How can possible enable login sound an installed Precise system?

[Hammer Attila]

Hy,

I have got a possible trivial question:
How can possible enable again the succesful login sound with an 
installed Precise system if an user using screen reader?
I tryed the startup applications preference tool. GNOME login sound 
service is presented, but unfortunately I see only following columns the 
tree table:
- Enable column (this is an empty column, nothing possible doing this 
column with keyboard), Orca says this column is empty.
- Icon column (this column shows the application icon).
- Name column (this column shows the application name).

Oldest versions of the startup applications preference tool the first 
column is a check box with possible checking or unchecking the required 
services.
