Why when I plug my AXE I/O ONE audio interface into my iPad Pro or iPhone 14 max no matter the USB cable, I always have a background noise (buzz) as soon as there is an accessory plugged into the analog input, while with a PC, I don't have this problem...
OK everything is fine, after further investigation, the issue was not from the AXE I/O ONE or the iPad... It was a defective part between... Sorry for that.
