Prior to calling setPreferredOutputNumberOfChannels:error:, an active audio session is required before asking for maximumOutputNumberOfChannels. It is important to note that they are optimized for the use case specified by each mode and setting a mode may also affect other aspects of the route being used. How can I translate the names of the Proto-Indo-European gods and goddesses into Latin? Instead use M:AVFoundation.AVAudioSession.SetPreferredSampleRate(Double, out NSError). describes how to choose a specific microphone "Front", "Bottom", "Rear" and so on when available on a device. Once I launch the app with none exterior mics hooked up and provoke the AVAudioSession Ive the identical log as Ive on iOS 16: Then I connect the iRig system (which is mainly the exterior microphone) and Ive the next log: As you see, the enter of the route matches the popular enter of the AVAudioSession. 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.
