I am trying to record direct to Cubase LE4 with a Line 6 Guitar Port, but I have terrible pops & clicks when I do. I have adjusted the Line 6 driver settings as low as they will go, but it doesn't help. Any suggestions? My PC is about a year old, Windows Vista, AMD Athlon X2. Do I need to get another computer, or is it an issue with my Line 6 interface? Thanks for any help or suggestions.
