DDJ RZX MASTER OUT NOT WORKING

Hello Pioneer,

Of recent I am having trouble getting master out from the DDJ RZX.

I have formatted my PC and reinstalled all drivers but sometimes the sound comes through and sometimes it doesn't.

I am currently using RB 6 ver 6.1.1

Also all drivers are up to date.

All terminals functioning and all volume and trim levels checked. 

Please assist ASAP.

If there is a log file you require then kindly send me instructions to get the log file and send it to you.

THANKS.
