Disable KDE sounds in GNOME Ubuntu

I use kate (a KDE text editor) under GNOME in Ubuntu. Since Natty upgrade, it plays miscellaneous sounds on error and other notifications.

I disabled sound notifications in GNOME, but kate sounds are still played. Kate itself doesn't seem to have any sound configuration, and I can't find any KDE configuration tool in the system menus.

How can I disable KDE notification sounds in a GNOME Ubuntu?

Install KDE settings package sudo apt-get install systemsettings. Then open it up and go to Application and System Notifications, Player Settings tab, set No audio output.

I do not see a reason for these bloody noises anyway. My solution that requires no installation of any more applications to take up space is to just delete the bloody noises: sudo rm -fv `sudo find /usr/share -iname *.ogg`

The previous answer is rather overkill as it will mute everything, not just the error beeps, in KDE and prevent you from hearing things you actually want to hear.

Instead of going to the Player Settings tab, the individual error noises can be disabled in the Applications tab.

In case of Linux Mint 18.3 installing systemsettings didn't work, because the settings window was empty. Here I've found that the following is sufficient without installing additional packages (besides Krusader that I already had installed):

kcmshell4 kcmnotify

Then Player Settings -> No audio output.
