I’ve connected my DDJ-FLX4 to my iPad via usb-c cable, the controller works fine, but I can’t select my audio output to my controller. Any solutions?

@DdoubleJ thanks for the additional information. Can you please confirm that the iPad is charging when connected to the FLX4? Have you tried a different USB-C to C cable? Preferably the original Apple one that came with your iPad or a high quality 3rd party cable with dual ferrite chokes on either…
