If it's the same for a line input, there is likely a fault on the mainboard; please contact a Pioneer DJ authorized service centre in your region to have your hardware inspected and/or repaired.
I've had my DDJ-1000s for about a year now no problems, suddenly today when trying to play on them, the master audio output is very quite even when turned up to the max. Also no sound coming through the headphones for cue. Have tried multiple cables (RCA and XLR), uninstalled and re-installed driver multiple times. Unsure what the issue could be.

Are you using a new OS, and what version of the software are you using?
I'm using Catalina and I've got the latest version of Rekordbox 6
@Hogard > Does the same thing occur if you play from an external line input? Or just from computer source?
Quiet from external line also
