I have a a45-s150 toshiba satellite and I ran MSCONFIG on it and disabled all things. I then rebooted and the sound stopped working . I re-enable all the stuff in MSCONFIG and still nothing happened. Before I did this I created a restore point and went back to that point and it still didn't work. I checked the device manager and there were no problems that I could see. In addition, I checked to see if it was muted and that wasnt it either I turned the sound all the way up nothing. Has anyone had a similar problem and do they know the solution?
