Hello, so there is no audio coming from the motherboard line out just a high pitch constant noise the loudness change if i change the volume it starts as soon as i boot, at first i though it was the speaker but it also occurs on my headphones and other working speakers as i stated there is no sound at all other than that loud screeching sound. THANKS IN ADVANCE.
P.S the sound also comes out on the line out in front of the pc.
