I'm sure its right infront of my face but i just got sony vegas pro 12 in the mail, i activated it and all. Everything went smooth, but as soon as i dropped in a video to edit i can't hear anything. I clicked a mute button to see if it was that but nope. I don't know what it is can anyone help? I have no audio coming out of my speakers when i preview my video
my sound on my computer is all the way up. But still nothing.
