1. Click on the logout button on the top right
2. Select System Settings to get to the Control Panel
3. Then just untick the GNOME Login Sound option - refer image below

Old info

One annoying issue in Ubuntu 11.04 is that there is no GUI to disable the pre-login sound that GDM (the Ubuntu login screen) makes when it opens. This ‘music’ becomes an issue when you work in a quiet environment

from the command line execute

gksudo gedit /etc/gdm/custom.conf

and add the line

SoundOnLogin=false

above the and the [daemon] line

save the file and restart - now you won’t hear the pre-login ‘music’ at the login screen
