Divide the problem into stages
Start with one known local track. If it does not load, investigate the file before changing speaker settings. If it loads and plays, inspect the deck meter and master meter. Their behavior helps identify where the signal stops.
Keep the test simple. Disconnect optional devices only when doing so will not disrupt another application or recording session. Write down a working setup before changing it.
Check the output you actually selected
The Windows default playback device and the output selected in VirtualDJ may not be the same. A USB controller can expose its own audio device while the laptop speakers remain the system default.
Inspect the application's audio configuration and the physical cable path. If the master goes to controller outputs, speakers connected only to the computer will not hear that output. Also check hardware level controls and whether the amplifier is on the expected input.
Test headphone cue separately
Use two different tracks and preview the quiet deck. Inspect the cue button, headphone volume and cue/master blend. An output that always follows the master may have been assigned to the wrong channel pair.
Consult the manual for the exact device. Do not copy another controller's channel numbers. A single conventional headphone socket does not, by itself, prove that independent stereo master and cue outputs are available.
Restore a simple baseline
Temporarily use the standard interface and a known audio configuration. Disable optional effects for the test. Save the current settings first so that changes are reversible.
If crackles occur rather than silence, consider the driver and buffer configuration separately. Change one setting at a time, listen again and note the result. Avoid unsupported registry edits or broad security changes.
What to send to support
Include the Windows version, VirtualDJ build, device model, driver details and a screenshot of the audio setup. State whether the master meter moves and whether a local track plays with the external device disconnected.
Should I reinstall immediately?
Not usually as the first step. A reinstall may leave the same routing error in place and make it harder to explain what changed.
Can a streaming problem look like no sound?
Yes. Test a known local file to distinguish catalog access from the output path.
