Some iOS devices support getting and setting microphone polar patterns for some of the built-in microphones. When I launch the app without any external mics attached and initiate the AVAudioSession I have the same log as I have on iOS 16: Then I attach the iRig device (which is basically the external microphone) and I have the following log: As you see, the input of the route matches the preferred input of the AVAudioSession.

There are several cases however where an application must first activate the audio session (after setting the appropriate category, category options and mode), in order to lean about the capabilities of the current configuration before being able to set a "preferred" value. This is an smallest example project to reproduce the issue. You should see if modifying your setup code and activating the session changes any behavior, and as a test even add an MPVolumeView to see if that allows you to pick the output/input you are intending to select by setting the preferred input/output.
