I've just got a key for performance mode and have started playing some tracks with a new DDJ-RB. About 20-30% of my tracks have no audio. They load into the decks and play, but there is no sound. I've revealed the tracks in finder, and the files are there and they play with sound in all other apps, just not in RB.
I've tried re-analysing the tracks but it still doesn't work. As far as I'm aware there's no auto-gain feature that could be going wrong.
The issue persists if the controller is disconnected.
Is there anything else I could be missing?
