FWIW - I had a similar Intermittent Crackle and Noise problem with my music computer a year ago. I did a ton of investigations, gave up and took it to a computer store. They had it for three weeks looking for the problem. Finally they happened to stumble on it. While they were testing it the problem happened. It turned out to be an intermittent problem with the power supply. They said that just happened to me at the right place at the right time.

Just thought that I would pass this on.

Intermittent problems, especially those that happen far apart from each other, at very hard to pin point.

PS - they said that every time they tested the power supply all was well.

My momma didn't raise a fool. And if she did it, was one of my brothers.
