I had indicator-applet after upgrade from Karmic to Lucid, but no indicator-sound. I expect such problems on upgrade, since I can't have ubuntu-desktop installed because it conflicts with fcron, which I need.
However, I notice that indicator-applet only recommends indicator-sound, it doesn't depend on it. That's probably why I didn't have it. I can't see any other meta-package which would have caused it to be installed. Maybe ubuntu-desktop should depend on indicator-applet-complete.
