I would try to boot to your install DVD that came with your Mac. (Hold down "option" as your boot your computer, select the disc)

This will boot your computer in to the OS X installer.

See if you get any sound now. If yes, then the problem is software, probably your user account. If you still don't have any sound, then you have a hardware issue.

(Don't go to far in the installer... you risk reinstalling your operating system and potentially erasing your data)
