IPhone 5 speaker stopped working all of the sudden?

My phone was working fine all day, and then the speaker just randomly stopped working out of no where. Siri doesn't work, music doesn't play, speaker phone doesn't work, no sound works at all. I didn't drop it or spill anything on it either. I restored it, and it still doesn't work.

Update your iphone to 6.1. This helped me when i was at 6.0.1 and the sound was really awkward and blurry. After updating it was all right.
