You either have a sound card or an audio chipset in your system that needs drivers to function. Install them, and you will not be living in silence.
Got a little sound problem here.
I reformatted my computer(WindowsXP) 2 days ago,And I got no sound anymore!
Thing is I dont have any sound card,I just use the Screen Speakers(So I just connect the wire from the Screen to the Comp,wich usually works) but now It dosent,My computer dosent even detect my headphones(I mean there no sound comming from it),Its pretty weird too cuz I went On ControlPanel==>System==>Device Manager and I got no Yellow "?"
Help plz ='(
