Comment 13 for bug 981335

hi,
Can any one tell me, how to disable the startupsound in ubuntu 12.04...

 I followed these steps..

$ gksudo gedit /usr/share/glib-2.0/schemas/50_unity-greeter.gschema.override

Add these lines:

[com.canonical.unity-greeter]
play-ready-sound = false

Save, then run:

$ sudo glib-compile-schemas /usr/share/glib-2.0/schemas/

--> The Sound is still comming. Its like text reader....
Please suggest me how to disable it....
