Here is what I am doing. I am going to add a FiiO K7 DAC/AMP to my iPad for audio. It would plug into the iPads single USB-4 port. Here is the problem with it plugged into this port I cannot charge the iPad with out unplugging the K7. I can do this, of course, but is it possible to to split this and be able to plug the iPad into both the Mac Studio, and the K7. The K7 has it own power supply. Right now I am using a FiiO BTR7 DAC/Amp. it is designed to work with such devices and can even be configured to be charged by them. The problem here is if I switch this in it eats the battery on the iPad alive. This iPad is the first USB iOS device I have ever owned so in this I am in uncharted waters.
