I have a brand new Toshiba Satellite laptop that doesn't have any weird viruses and has never had to be re-installed, nothing like that. Well about a week ago my speakers just suddenly stopped working. The volume is up nothing is muted. I have checked all the audio componants and I see no yellow yield sign beside them. I don't think I could have blown them, I haven't turned it up any louder than the bar will let me go. Does anyone know what could be the problem?
