Sam, Sorry for my late reply.
Regarding the bug with the iPad Pro detecting all USB audio devices as Headphones (wired devices): I have now access to the name and UID of the port, so, indeed I can now find a workaround. However, is there any reason why AVAudioSessionDescription portType stopped returning USB devices on iPad Pro? Will it be deprecated or is it still a bug? I cannot test it here but is there the same problem with HDMI devices?
