[QUOTE="EvenStranger, post: 1171682, member: 181804"] First thing I'd do is reset the PRAM. Power off the system. Power back on and hold down the Command-Option-P and R keys, and see if the system will give you a startup chime. If not, your sound board (Left I/O board) is hosed. If you can get a startup chime, but still no sound internally, try launching GarageBand and see if it will reset your sound drivers. [/QUOTE]
