Welcome to Android Central! So no sound comes from the main speaker at all? What about the earpiece speaker--can you hear calls ok? You've checked the Settings>Sound menu to check on all of the volume settings? And it persists after rebooting?

It may be a hardware failure. If the phone is 9 months old, it should still be under warranty, so contact Samsung.
