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):

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.

    Setting it to 0% had no effect for me. but pressing the mute button did. – ctrl-alt-delor Aug 04 '17 at 12:24
  • @ctrl-alt-delor - only now I've got your point, seeing the same occurrence in Kubuntu. Edited my answer. –  Feb 05 '18 at 09:15
  • Just muting notification sounds didn't help me. The slider became grey, but the volume level was ca. 70% and the notification sounds were still active. I also had to set the volume level to 0%. This is somehow counter-intuitive. Must be a bug. – ka3ak Jan 10 '20 at 18:07

    I used `pavucontrol-qt` to set volume > 0 since it was stuck also in main control but the the program I am using, Hexchat, is still not making any sounds. – Răzvan Flavius Panda Apr 14 '20 at 20:41
  • The slider is bugged: shows that it's muted, but it's not. – Velkan Apr 25 '22 at 07:37
  • Thank you. This is still bugged 7 years later. I will log it on the KDE website. – Richard Jul 06 '22 at 10:07

On KDE Plasma 5.22, Open System Settings, navigate on the menus to this place: Application Settings window and click the "Configure Events" button. This window will popup: Configure Notifications window here you can disable/change the system sounds on an individual basis.

  • But how to do it in one click? alternative for "No Sounds" theme in Windows, we have to visit each possible app and check if any event has sound notification enabled. – Maxim Aug 13 '23 at 16:20

in kde5, as root:

cd /usr/share
mv sounds sounds.backup

It's very annoying, isn't it? I haven't found a way to disable it but muting it is easy. Fire up kmix, scroll down "Event Sounds" to the bottom. Job done.

  • Very odd, but I cannot find that. Kmix (version 4.6RC1) contains but 4 tabs: Playback Devices, Capture Devices, Playback Streams and Capture Streams. I see no Event Sounds anywhere. –  Jul 06 '15 at 14:16
  • This works for me. The Event Sounds slider is in the Playback Streams tab. – Bennypr0fane Mar 16 '23 at 23:44

I think I've been able to resolve this by switching to the Gstreamer audio backend instead of VLC. Once I switched backends, Kmix showed a new "PCM" slider which seems to affect notification sounds.

  • Well, this seems half correct now that I've had it set for a while. PCM does affect notification sounds, but that includes ALL notification sounds regardless of app; so now I can't hear my Pidgin chat alerts. – danarchy85 Jun 17 '16 at 02:46
