STEPS TO REPRODUCE 1. make sure the system sounds are disabled in System Sounds KCM 2. open Kolourpaint 3. draw something 4. try to close Kolourpaint without saving the draw OBSERVED RESULT Kolourpaint prompts to save/discard the draw and plays a notification sound EXPECTED RESULT the notification sound should not play SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 6.0.2 KDE Frameworks Version: 6.0.0 Qt Version: 6.6.2 Graphics Platform: Wayland ADDITIONAL INFORMATION Can also reproduce with K3b.
Is this still an issue on an up to date system?
Unfortunately this is expected and not much that can be done about. Contrary what it may seem, it is the apps which play the notification sounds and not plasma. In the case of KDE apps, this is usually done via the KNotification frameworks. The setting property to disable notifications, along sound themes, was added on KNotifications for Frameworks KF6. So applications that still use KF5 don't know about this setting and cannot be affected by it. The only configuration that can make the notification sounds not play for every app is muting the "System Notifications" channel in the "Audio" KCM, because that's done at the sound server level (pulseaudio/pipewire). That means, the sound is still "played", but will not be emitted because it is muted.
Thanks for the explanation. I'm going to go ahead and close this, since the system is working as designed.
