Hi I am facing the following strange problem. Please let me know what am doing wrong. Problem:- On board speakers not working suddenly( was working fine a day back). Did a mute(using the button in the keyboard) and then tried unmuting but no sound. However my microphones are working.My friends can hear me in yahoo/gtalk. Steps Tried already:- 1)Checked for mute in volume controls.Not muted. 2) Tried "Test Hardware" in laptop. I can see the green light working fine(it goes up and down) in playback but again no sound that I can hear. 3) Checked for drivers of sound and audio.No errors(no yelllo). The device(Sound Max Audio) is enabled and it says working fine. 4) Tried "System Restore" to 2 days before but again no sound. 5) Tried using headphones no sound again. What could be the problem?Any ideas. I will update this thread with some more info if i do any..In the meanwhile if anyone can help me it would be great.
