Login sound still plays despite disabling from administration login screen

In maverick, I get the login sound when my computer starts up and I auto-login.

The happens despite the fact that I've turned off the "play login sound" on the administration > login screen dialog.

How can I turn off the login sound playing?

From ubuntu Davious

• Maybe try Preferences > Startup Applications > Gnome Login Sound, and disabling it.

  EDIT: I would also like to add that you change the sound to your whim: you could put any 10-second sound when Ubuntu starts up.

  Davious : Yes, thanks for helping me out.

• The login screen dialog dictates what happens when GDM (The login screen loads) The sound you're likely referring to is actually the GNOME Login Sound which can be disabled in the Startup Applications windows under

  System > Preferences > Startup Applications

  

  Davious : Ah, yes, thanks.
