How to disable event sounds in Plasma 5? I wander how to disable event sounds in kde5 Plasma (the one that is heard when scrolling the volume in systray for example). I use Plasma in Opensuse 13.2 but this is KDE specific methinks. * * * UPDATE These are the available settings (after answer): !enter image description here !enter image description here

In recent Plasma 5, search "Audio Volume" in the application launcher and, under 'Applications' tab, disable 'Notification Sounds'.

**In some Plasma versions the above doesn't work** , as I now see in Kubuntu 17.10. The Audio Volume tool looks different and notifications sounds is already muted.

To stop the volume scrolling sound etc in this case, I have unmuted, and moved the slider to zero, and muted again. Something is buggy here though, as the slider is in fact always stuck to zero, and only the mute/unmute button does the work.

In this case I have noticed that a different tool can be used: `pavucontrol-qt`:

After using this, the bug mentioned (slider stuck to zero in "Audio Volume") disappeared.
