Sonar's CD burner popping sound

Every CD I have burned using Sonar's Utility to burn a CD ends up with a popping sound when it switches tracks. It's on the 2 seconds that it puts at the beginning of track. It's not crazy loud or anything. The average listener probably would not notice it. But of course, I do. Just curious if anyone else has ran across it and if so, any solution or is this something that just happens when burning to CD-R? Not really an issue - just annoying because I always notice it.

Oh yeah - SPLAT, HP ENVY.

I am going to try some other CD burning utilities and see if it does it.
