Version: (using Devel) Installed from: Compiled sources OS: Linux Enabling the "Use system bell ..." setting in System Settings -> Notifications -> System Bell isn't enough to enable the system bell beep. You also have to enable "Use system bell" in the Accessibility -> Bell module which took me quite some time to figure out.
It would be a good idea to merge those two.
This is related to bug 56903
I would say that this is a dupe. As FiNeX pointed out in the other bug. the problem still exists in KDE 4.2.x.
Marking as dupe of bug 56903. Thanks *** This bug has been marked as a duplicate of bug 56903 ***
