djay Pro 2 Pre-Cueing Noise/Issue

Hi there

I have just bought djay Pro 2 for my MacBook and I love it!

The only problem I am having is almost every time I load up a track in my headphones for pre-cueing, some noise start destroying the music, but only in the headphones - out loud there’s nothing wrong with the music. After around 10 seconds I can’t even hear the song in my headphones for the noise. It gradually gets higher.

I have recorded the noise from headset here:

My mixer-mode is on internal. Main output is “Built in output” and my pre-cueing is set to my mixer, the Pioneer DDJ-RB where my headphones are plugged in.

It is really annoying and I hope someone can help!
