I have KDE as the window manager, and I cannot figure out how to stop it making ding-a-ling noises at extreme volume. Example:

  1. Open Konsole.
  2. Open a second tab.
  3. Close the whole window with its × button.
  4. A message box interrogates me, asking if I really want to close both tabs. The message box resets the system volume from where I need it for my headphones, ~10%, to 100%, and then emits a pointless ding-a-ling noise. It's horrifyingly loud. I jump every time.

I haven't done anything weird with the sound settings to cause this. Linux has behaved this way since I set it up a month ago.

Question: Where is the checkbox to turn off KDE's noises? It was easy to turn off the sound theme when I used Windows, but I feel like I've looked all over KDE and never found the setting. Currently I live in fear of clicking things that I know will make the noise.

System: Debian Stretch 9.5
KDE: Plasma 5.8.6

    I live in fear of clicking things .... has it occurred to you to remove your headphones until you figure out how to turn down the volume? – jsotola Oct 1 '18 at 6:35
  • @jsotola That's what I mean. I take them off when I need to click something that will make the noise, if I'm aware that it will, or I do things a different way that won't cause the noise. But I'm using my headphones. Why can't KDE just stop changing the volume and stop making ridiculous extreme-volume noises? I don't understand why this is a difficult question. Where's the checkbox for the noises? Why isn't everyone else experiencing this problem? – Boann Oct 1 '18 at 13:57
  • you are using the wrong term .... searching the internet for noises will not give you any answers ..... search instead for kde system sounds and you will find an answer – jsotola Oct 1 '18 at 19:01
  • @jsotola I did try. – Boann Oct 3 '18 at 4:05

Open System Settings and click on Notifications: System settings

In the Notifications window, first select the event source for which you want to configure notification, in this example, I chose Plasma Workspace. In the table, the first column reflects the state of an event. When a sound has been configured, a little play button is displayed. If you want to disable the sound for a certain event, click on the event and deselect the Play a sound checkbox. You can quickly disable all sounds for a certain event source by clicking the button Disable sounds for all of these events.

Notifications

If you want to disable all notification sounds, you have to select each event source and click the "disable all" button. AFAIK, it's not possible to disable all sounds with one click.

However, it is possible to mute them. If you go again in System Settings -> Multimedia -> Audio Volume, you can simply mute all notification sounds: Mute notification volume

    I couldn't find "Plasma Workspace" as an "event source" in my version of KDE. I was going to say so, until I accidentally scroll-wheeled onto more event sources! Originally I only ever found the first ten, because the scroll bar for that list is way over on the other side of the screen, so I never noticed it. After disabling all sounds in all event sources as you suggest, yes, finally KDE shuts up! Thank you! By the way I'd already been to Multimedia -> Audio Volume, and already set Notification Sounds to 0%, and muted it, and that setting seems to have absolutely no effect. Never mind! – Boann Oct 3 '18 at 3:23
  • glad i could help, enjoy the silence ;) muting works too in my case, but I guess that's some whole other problem (pulseaudio releated i guess) – mxttie Oct 3 '18 at 10:13
