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.
