Doing some support checks, the Via issue is about two/three years old, so I doubt that is your problem. Like everyone said, check the PS. Although, a lot of posts mentioned IRQ issues causing noise disturbances with the Audiology.
"I have come to believe that a great teacher is a great artist and that there are as few as there are any other great artists. Teaching might even be the greatest of the arts since the medium is the human mind and spirit." John Steinbeck
