0x15 (SPXERR_MIC_ERROR) Exception with an error code: 0x15 (SPXERR_MIC_ERROR)

IN ORDER TO ASSIST YOU, PLEASE PROVIDE THE FOLLOWING:

• Speech SDK log taken from a run that exhibits the reported issue. 0x15 (SPXERR_MIC_ERROR) Exception with an error code: 0x15 (SPXERR_MIC_ERROR) I'm a newbie not very good at finding logs, but this error is definitely showing up and can be reproduced without a log file

• A stripped down, simplified version of your source code that exhibits the issue. Or, preferably, try to reproduce the problem with one of the public samples in this repository (or a minimally modified version of it), and share the code.

  
  SPXSpeechConfiguration *speechConfig = [[SPXSpeechConfiguration alloc] initWithSubscription:@"4c894fXXXXXXX9cea" region:@"qatarcentral"];
  if (!speechConfig) {
      NSLog(@"Could not load speech config");
  
      return;
  }
  
  SPXSpeechRecognizer* speechRecognizer = [[SPXSpeechRecognizer alloc] init:speechConfig];
  if (!speechRecognizer) {
      NSLog(@"Could not create speech recognizer");
  
      return;
  }
  
  SPXSpeechRecognitionResult *speechResult = [speechRecognizer recognizeOnce];
  if (SPXResultReason_Canceled == speechResult.reason) {
      SPXCancellationDetails *details = [[SPXCancellationDetails alloc] initFromCanceledRecognitionResult:speechResult];
      NSLog(@"Speech recognition was canceled: %@. Did you pass the correct key/region combination?", details.errorDetails);
  
  } else if (SPXResultReason_RecognizedSpeech == speechResult.reason) {
      NSLog(@"Speech recognition result received: %@", speechResult.text);
  
  } else {
      NSLog(@"There was an error.");
  
  }
  ```objective-c

• Additional information as shown below

Describe the bug I configured the key, instantiated the object, and got an error when I started speech-to-text. But I found that I can convert speech to text, I just can't call the microphone for real time speech to text, I checked the microphone permissions, and they are there! Note that I am hybrid app. i am calling IOS method in webview

To Reproduce

Steps to reproduce the behavior:

1. Create a hybrid app and copy the code above
2. Triggering this method will report an error

I copied the official example, no error can be normal to text, I am a hybrid app, in the web view to call the error

Solved, the following code needs to be added

audioEngine = [[AVAudioEngine alloc] init];
    audioData = [[NSMutableData alloc] init];

    AVAudioFormat *outputFormat = [[AVAudioFormat alloc] initWithCommonFormat:AVAudioPCMFormatInt16
                                                                   sampleRate:16000
                                                                     channels:1
                                                                  interleaved:NO];
    AVAudioSession *audioSession = [AVAudioSession sharedInstance];
    NSError *error = nil;
    [audioSession setCategory:AVAudioSessionCategoryRecord mode:AVAudioSessionModeMeasurement options:AVAudioSessionCategoryOptionDuckOthers error:&error];
    [audioSession setActive:YES withOptions:AVAudioSessionSetActiveOptionNotifyOthersOnDeactivation error:&error];
    inputNode = audioEngine.inputNode;
    AVAudioFormat *inputFormat = [inputNode outputFormatForBus:0];
    AVAudioConverter *converter = [[AVAudioConverter alloc] initFromFormat:inputFormat toFormat:outputFormat];
