The key is calling the SetCategory with the appropriate AVAudioSessionCategory and setting the session to active.

Like:

var session = AVAudioSession.SharedInstance();
session.SetCategory(AVAudioSessionCategory.Playback);
session.SetActive(true);

You could use DependencyService to set it in your ios project.You could refer to https://learn.microsoft.com/en-us/answers/questions/320860/isimpleaudioplayer-issues-on-ios-and-with-speechre.html.
