For those who have been playing with KDE 4.8.0 that was released yesterday, you might noticed that your KDE will not ring any sound when you logged in anymore. I noticed this earlier, but i thought that there was some backend problem and i haven't had time to find the solutions for this.
AJ Field commented on Eric's blog post about KDE 4.8.0 and pointed a thread at ArchLinux Forum which should solve the problem. I tried to use the solution written there and it really work like a charm.
The problem only lies in the directory reading on Notification settings (System Settings -> Applications and System Notifications). Previously, you mentioned only the filename, but in KDE 4.8.0, i guess it should have been a complete path, so the solution is simple, just browse the file and pick the same file and it will give you the full path.
I'll show you before and after i changed the path using these two screenshots below. The first screenshot is the original condition:
This is what i got after i browse the file and pick the same filename.
I only need to save the changes and it will be back to normal again once you logged out and logged in again.
