Problem is that every time I click something I get annoying sound from computer speaker. So I tried to disable or set new sound theme by visiting System > Preferences > Sound. The Sound Theme tab is greyed out. Sound itself is not working and I can only get annoying sound. How do I fix this problem under Debian or Ubuntu Linux gnome desktop system?
The GNOME Volume Control application is an audio mixer that enables you to mix audio for two-channel sound cards. It may be disabled if you removed or did not installed freedesktop-sound-theme package:
To fix this problem open a terminal and type the following command:
$ sudo apt-get install freedesktop-sound-theme
