sounds in kubuntu

Hello, Workrave is not playing sounds in Kubuntu. This seems to be an 
unusual problem because I've only found one other report of it, and the 
proposed solution was, "Install Mepis." Basically, sound is working: music 
plays, YouTube works and Workrave's wav files will play in Amarok, but 
Workrave itself will not play the wav files during breaks or in the preferences 
box. I'm also seeking help on the Ubuntu forum.
