I'm guessing you've checked to make sure all your sound settings in Preferences are correct? Maybe it switched over to the optical outputs or something? Unfortunately troubleshooting recommends a logicboard replacement if an audio failure occurs. Personally I would do everything possible to make sure it isn't software related. Reinstall Mac OS if you have to. Can you log into another account to see if audio works there?

You can also try possible resets: PRAM and PMU.
