Ddj1000 and rekordbox can’t get the headphone cue to work

Hi,

We have been trying to use headphones with our ddj1000 but for some reason it won’t work through the out. We can get the cue to work but it just plays out of the speaker we are using not the headphones when we plug them in. We have tried making a new audio input through our Mac settings but it won’t come through the headphones. Is there something we are missing?

Thank you
