My DJ controller is detected in Traktor Pro 2, but there is no sound

If your DJ controller has a built-in audio interface:

• Connect your speakers to the DJ controller's Master output, or output 1-2 (not to the computer's audio output).
• Connect your headphones to the headphones output on the DJ controller.
• In Traktor's Preferences options (macOS: Traktor > Preferences / Windows: Files > Preferences), go to Audio Setup and make sure that your DJ controller is selected as the Audio Device.

• Go to Output Routing, and make sure that:

- The Mixing Mode is set to Internal.

- The Output Monitor is assigned to channels 3 and 4.

- The Output Master is assigned to channels 1 and 2.
