In windows there is an option call no sounds.
Is there anything like that in unity / ubuntu 11.10?
I don't ever never want a system kind of sound.
Three simple steps:
To disable system sounds check Sound Settings
:
Mute Alert Volume
:
To mute the Login Sound
open Startup Applications
:
Disable GNOME Login Sound
:
To disable the alert on the login screen (lightdm) you have to mute it once - it is muted automatically next time you start your system:
Done.
Go to the Dash, type "Sound". The sound menu opens. There you can mute all system sounds.
Another way to do this is to install dconf-editor
(sudo apt-get install dconf-tools
from the Terminal) and head over to org > gnome > desktop > sound and uncheck 'event-sounds'.
