Gnome Volume Control: Disabled Sound Themes

Posted on in Categories last updated May 26, 2011

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?

Can you suggest a few free FOSS apps that works as alternatives to Photoshop under Ubuntu or Fedora Linux desktop operating systems?
