위 누겟을 사용하여 마이크 녹음을 처리하고 있는데 iOS 에러 아래와 같은 에러가 발생되었다.

'audioQueue.Start() returned non-OK status: GeneralParamError'

처음에는 파일 저장문제 인줄 알았는데 깃헙 이슈에 여러사람이 위문제를 물어보고 있었다 

답은 

AppDelegate.cs 에 아래 내용을 넣으면 된다.

AudioPlayer.RequestAVAudioSessionCategory(AVAudioSessionCategory.Playback);  AudioRecorderService.RequestAVAudioSessionCategory(AVAudioSessionCategory.Record);

    // The UIApplicationDelegate for the application. This class is responsible for launching the 
    // User Interface of the application, as well as listening (and optionally responding) to 
    // application events from iOS.
    [Register("AppDelegate")]
    public partial class AppDelegate : global::Xamarin.Forms.Platform.iOS.FormsApplicationDelegate
    {
        //
        // This method is invoked when the application has loaded and is ready to run. In this 
        // method you should instantiate the window, load the UI into it and then make the window
        // visible.
        //
        // You have 17 seconds to return from this method, or iOS will terminate your application.
        //
        public override bool FinishedLaunching(UIApplication app, NSDictionary options)
        {
            global::Xamarin.Forms.Forms.Init();

            CrossMediaManager.Current.Init();
            AudioPlayer.RequestAVAudioSessionCategory(AVAudioSessionCategory.Playback); 
            AudioRecorderService.RequestAVAudioSessionCategory(AVAudioSessionCategory.Record);

            LoadApplication(new App());

            return base.FinishedLaunching(app, options);
        }
    }
