So you know how when you go to volume mixer and you see the green sound bar move yeah well no matter what Chrome, VLC or even a game NOTHING happens. it plays no sound so I can't watch Youtube or listen to music. I have windows 7 Black Edition and NEED to catch up on some Youtube channels plz halp (my computer has a built in speaker but even headphones and aux speakers don't work)
