I tried switching to the MME drivers and got virtually nothing. Maybe I should explain my setup, I use a Line 6 UX2 guitar interface as my input, and the computer's card as the output. I tried messing around with the buffer size, but I have no idea which one I am playing with, I found buffer adjustments in 2 or 3 different places. I can use any advice anyone can share on setting up these buffer settings. When I play the track, I'm still getting various buzzes lasting about 1 second at different frequencies and different volumes. I guess I need a plan of action in order to know where to look for the problem, as opposed to trial and error, which is what I have been doing.....................thanks folks!
