This is a new one, playing as usual from my exported USB drive and all of a sudden there's no sound. The waveform on the player, a 900 NXS, was visible and scrolling but not a bleep coming out to the mixer. Quickly threw in the next song from the other CDJ and thought it was a fluke. Next night same thing happens to same song but on a different machine, original 2000.
At home I copied the file from my USB to my computer and discovered that the exported file has a 42 second gap of silence in it. Since both players showed correct information and waveform for the song I don't think Rekordbox is the culprit here, my guess is that the computers OS, High Sierra, has failed to copy the file properly to the USB.
I will save the file for a while if Pioneer wants to probe it, just let me know!
