Well, a quick Google search turns up an Apple Discussions thread listing a number of possible causes:

http://discussions.apple.com/thread.jspa?threadID=1197549&start=0&tstart=0

...among which seem to be 3rd party peripherals and more than one audio-related app. You might read through that thread and see if any of the software/hardware mentioned is something you've got installed.
