I'm having the same problem. I have the hum in the exported file whether I'm using the onboard Realtek sound card or using my Zoom H8 as an external sound card. The hum is at exactly the same level regardless of which sound card I'm using. I've also tried this on two separate computers with the same frustrating results. There is absolutely no noise when listening to the track in Cakewalk. I'm trying to put a project to bed and this problem is like hitting a brick wall! Please help!!!
