WARNING: the usb-c cable does not work with iPad Pro :(
I was really hoping to standardize my ecosystem on USB-C but unfortunately the final piece did not fall into place. When I plug the cable into the iPad Pro nothing is detected and sound keeps coming out of the ipad speakers. The same cable works fine with a Thinkpad and with Pixel 3. The iPad pro has both analog passthrough and digital audio support so I am lost as to what the problem could be.
