Hello: well I thought I had the problem solved with Sonar; I diabled the onboard soundcard, disabled all items in the start menu, and turned everything off in the background. When I recorded a second track last week I heard no crackling. However, when I went back on for the first time since then, and played the file, I heard crackling. I changed the buffer size again and it was fine. I restarted, heard the crackling again in play back, changed the buffer size, (either up or down), itdoesn't much matter), and the crackling stops. In short, every time I restart, there's the crackling until I move the buffer size. Does this give anyone some ideas as to the source of the problem?
