Version: 2.2.0 (using KDE 4.3.2) OS: Linux Installed from: Ubuntu Packages Powertop shows that Amarok causes many wakups per second (about 15%) even when it is not playing any file and only the tray icon is visible. "amarok : hrtimer_start_range_ns (hrtimer_wakeup)" Probably a timer needed for for playback or for some visual effects is not disabled when reduced to icon/hidden to tray icon.
