Want to change default theme sounds

I am running openSUSE 11.1 Gnome version. I want to change the default sounds that play when you login, etc. I need help changing to new sounds as I cannot find a way to do it

Thanks

Go to Control Center → Sound

Select “Login” and click “Default” in front of it.

From the menu click “Custom” and choose a sound file to play at login.

Note: The sound file should be small, like around 10 sec.

Thank you for your reply. With your help I can now open the default sound.
