You'll have to run cables back from the controller to the laptop on a line in port if you have one.
The audio output is designed to be routed out through The master out of the controller to speakers, not to be played through built in speakers.

alexbell962 - I have very same issue with DJ2GO2. I'll be interested to see how you get on.

When you plug the controller into your computer in routes the audio through the controller. that being said look at the outputs on your controller probably rca or trs(1/4) and get and adapter to 3.5mm or if worst comes through worst run it through your headphones lol

Hi, I have the numark party mix and everything is set up working fine through speaker but I have no sound through the headphones.

Please any help would be useful

you gotta do what we call cuing. to cue the track press the headphones button on the side u wanna hear.

I press the headphone button on both sides and still nothing. The headphones work fine as tried on my phone but for some reason no matter what I do no sound from headphones

And what is the cue gain and cue mix set to?

Hola, buenas tardes, ayer compré la Numark Party Mix y me pasa lo mismo. No tengo audio, tengo una terjeta de sonido externa y quiero que salga el sonido por ahí y la preescucha por la numark, soy novato, novato.... si me echan una mano, lo agradecería.

I have the same problem, I followed the suggestions without results. Cue Mix and Cue Gain levels are at 100%.
Any new idea, guys?

Hi I have the same problem, I have called Unmark they sent me few articles but none worked

When I play music coming from the Laptop through the controller the music plays well, but when I use Serato nothing comes out of the speakers
