DDJ-800 no master audio output Big Sur 11.2

Is anyone else having issues with Big Sur 11.2, the DDJ-800 driver and master audio out?

I have just managed to install the driver OK after many attempts, and as per this thread for a similiar DDJ-1000 issue. (IE the driver is successful after the System Extension Updated prompt appears).

However I still have no master audio out what so over, any ideas?

Rekordbox is listing "DDJ-800 : Master" as the master output but there is no output
