I am having trouble burning CDs. I down load as flac then convert to wav and burn via “Ashampoo burning studio” I have been doing this for several years with no mishaps but now I am getting crackles on the burned CD and suspect the DVD RW drive I have never cleaned or dusted it. The wav files stored on PC play perfectly so it points to the drive. I am tempted to put a vacuum nozzle in the region of the open CD tray and see if that fixes it. I run a DELL desktop and Vista Home.
