I'm having trouble with the sound working and then not working. Last night, I got a message which said something had been unplugged and it showed a speaker but nothing had been plugged in nor unplugged. I have ran diagnostics and the tones I hear fine yet when I go to view a video I have no sound. I have to restart the computer to bring the sound back. Please tell me what needs to be done or what I can do to check or correct the problem.
Thank you,
Teresa Gartin
