Are you using PRIME for Mac with an audio interface? Or another setup? If you are using an interface with PRIME for Mac and are hearing a static or crackle in your audio, for now you will have to use the built in click in PRIME. Go to your settings, turn on "Generate Click Dynamically" then go to "Edit Song", "Edit Markers" and add one section marker. This should fix the audio issue. Our development team is working on fixing the issue so you don't have to use the built in click.
Hope this helps! Let us know if you are using a different setup.
