My hp pavillion dv7-1245dx has no sound, the volume is at 75, I already ran a diagnostic, windows fix it and found that everything is working perfect, but the orange ligth keeps on, if I press it the only thing that change is the volume control on the task bar from sound to no sound, but it keeps orange, never blue, this problem started about a week ago after I upgraded itunes, I restored my computer but the problem continues.
Windows 7 64bit,
help please, thank you
