Sound working in Gnome but not KDE

edit

So I have always been a Gnome user, but now with Gnome 3.... Well... You know.

So I'm using KDE, but my sound isn't working. Seems to be a fairly common thing judging by my Google searches, but I have yet to find a fix for it. Anyone have any suggestions?

[EDIT]

I should mention that the sound works fine if I boot from the Fedora Live KDE spin CD.
