Okay, so all notifcation audio, such as the trash emptying, the incoming mail alert, logging into iChat, etc, will not play. All other audio works fine. I tried the GarageBand fix to no avail. This is really annoying. 
Have you restarted? Do you have any speakers plugged in? Have you taken your baseball cap off and shaved?
The audio settings are stored in the SMC memory, if that goes doolally, it can muck all the sound settings up...

Only some of the settings are stored there, but obviously the doolallied setting was. What does doolally mean?![]()
Head cold, can't sleep. Here we go, doolally. I should've known, really...![]()
GAH!! It screwed up again! What does this mean?
It means the universe is coming to an end and we're all going to die.

No, seriously, it could be some kind of electrical circuit glitch. What all is plugged into the same circuit with your computer? Though unlikely, it could also be some kind of software-induced thing. Have you installed anything lately?
