no login sound in 12.04

[José Vilmar Estácio de Souza]

Hi all.
What happened to the login sound in 12.04?
I can hear the drum sound before orca but I do not hear the login sound 
after I type my password and press the enter key.

I read that  I can enable the login in the start up applications but I 
didn't find it in the start up applications.
Thanks.
