Click on the "DDJ-SX3" button and make sure you have your speakers connected to the Master Output of the DDJ-SX3. You can still change the Audio Setup from Settings->AUDIO tab.
Click to OK.
The unit is now ready to operate with VirtualDJ.
The unit should be visible in the MAPPING tab of Config and the “factory default” available/selected from the Mappings drop-down list. The factory default Mapping offers the functions described in this Manual, however those can be adjusted to your needs via VDJ Script actions.

The unit has a pre-defined Audio setup and a special button in the AUDIO tab of Config to provide that. Since the DDJ-SX3 requires an "External Mixer" audio setup, your speakers need to be connected to the Master Output sockets at rear panel of the unit.
Please read the manual of DDJ-SX3 for further functionality https://www.pioneerdj.com/en/support/documents/ddj-sx3/
