I have also had this problem in several projects recently, which has been extremely frustrating. CC 2017.1.2. Clearing the media cache does nothing. I was happy to see this post; presently I am getting a loud BUZZ noise whenever an audio clips begins in a different track than the last one. In my last project, the audio would not buzz, but would drop out for about a second when the track changed. The problem remains on export so it can't be "baked out." For my current project, I believe the problem can be isolated to the "vocal enhancer" effect. I applied this effect to three tracks in the timeline, but when disabled, the buzzing is not present. That'll have to do for now, but my audio quality is suffering as a result. I swear, the amount of time I spend chasing workarounds on bugs meets the time I spend on my projects. Who has the time for this?
