Reproducible: Always Steps to Reproduce: 0. KDE 4.7.4 and upwards (possibly earlier versions) 1.System settings / Application and System Notifications: Player Settings: Assure, that "Use the KDE sound system" is ticked. 2.System settings / Multimedia / Phonon / Backend: Assure that GStreamer is the Phonon backend (here version 4.5.1.) 3.Open Terminal, run "top", let the system go idle. knotify4 is on top (using 2% CPU, speed dependent, of course) 3. Disabling sound notifications to "No audio output" (log out after setting) or using vlc as the phonon backend makes CPU usage go away. Calling it a major bug as it consumes loads of CPU cycels for no good, causing thermal heat, dying laptop batteries and makes upcoming RC6 GPU sleep rather pointless for KDE gstreamer default installations.

Could you please upgrade and see if that still happens for you?
