Why can't i hear videos?

Question

This morning I was watching videos on you-tube and movies on my computer and the sound was working absolutely fine.

But tonight when I try to play any videos I can see everything fine but no sound is coming out.

Please help me, Its driving me insane!

Answer 1

test out your sounds on other things, maybe ur internal speakers shot out

that's weird, maybe right click and see preferences or something see if it's on mute. if not idk sorry =(

Answer 2

did you turn the sound on?

Answer 3

if you are using a pc, perhaps the speakers are unplugged. =/

test the sound is all i can suggest. =]

Answer 4

maybe your speakers' wires lose?
