I would like to record videos of myself playing musical instruments and have the sound being fed via my USB-C audio interface (MOTU Ultralite MK5).
I have tried the answer given in another post but this doesn't work on an iPhone 13 mini.
I first connect a Lightning to USB-C cable to my iPhone, open the camera app, choose to record video, then plug the USB-C end to the MOTU UL 5, and finally click record. I then play a few notes on my digital piano which is plugged into the MOTU UL5 and can see levels on the MOTU UL-5 meter.
However, on review of the recorded video there is no sound.
