I was watching a few youtube videos and suddenly all sound is gone. I didn't mute it and i put all sound things to the maximum but still no sound. The thing is, usually when I hover the mouse over the speaker at the bottom right, it shows some kind of movement that shows the loudness of all sound, even when mute. This moving thing was not there though. So it's not just some mute thing, something is actually messed up. Can anyone help?
ps. I have windows vista
