I just cannot figure it out ... my sound system works. Banshee is happy and so is Skype. Skype's event sounds (ringing etc) are correctly controlled by the alert volume slider in sound preferences. However, the alert sounds from the desktop system itself do not work when I select the LinuxMint sound theme. I can select one of the builtin alert sounds (bark, drip, glass, sonar) and these will work. But the LinuxMint sound theme ... no go.
Does anybody have an idea on how to fix that? To me that looks like as if the the sound preferences knows that there is a LinuxMint sound theme, but the actual sound files are in the wrong place or something like that.
