DDJ-400 no master audio output

Hi all,

My DDJ-400 Master Sound output is not working.

I am using Mac OS Mojave 10.14.6

In Rekordbox sound preferences, DDJ-400 is selected and Master output is DDJ-400 Master and headphones output is DD-400 phones.

Have also reinstalled everything from the scratch but without luck.

@Pioneer support. would appreciate your response here

Cheers
