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 1. Can you please provide a screen shot of your Settings\>Audio Device Setup when the FLX4 is connected to the iPad? 2. Can you confirm that your iPad is connected to the computer/tablet USB-C port on the back of the FLX4? 3. Is the FLX4 connected to power via the second USB-C port on the back? ![IMG_0502](https://community-assets.algoriddim.com/original/2X/0/032b6a6bbe688f3a611dafdf2db3e8cb251a1ed9.jpeg) ![IMG_0503](https://community-assets.algoriddim.com/original/2X/0/0b28763bb652de727c2690584714460bd50844a5.jpeg) ---

@DdoubleJ thanks for the additional information. 1. Can you please confirm that the iPad is charging when connected to the FLX4? 2. 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 end. 3. I would also try disconnecting everything, doing a Forced Restart of your iPad, then launching djay, then connecting the FLX4 to power, then finally connecting the FLX4 to your iPad.

Hi Slak, 1. A forced reset of the iPad fixed the problem 🙄 Thank you for your help, much appreciated 🤝 ---
