On Android, services-speech-sdk SPXERR_AUDIO_SYS_LIBRARY_NOT_FOUND

### Tested versions

godot4 dev6 c#

### System information

android 11 api 30

### Issue description

On Android, I have already granted the recording permission. When I use the cognitive-services-speech-sdk for recording, I encounter the error code: 0x38 (SPXERR_AUDIO_SYS_LIBRARY_NOT_FOUND). How can I resolve this issue? Is speechsdk not supported, or is there another reason?

### Steps to reproduce

SPXERR_AUDIO_SYS_LIBRARY_NOT_FOUND

### Minimal reproduction project (MRP)

```csharp
public async Task FromMic(SpeechConfig speechConfig)
{
var pronunciationAssessmentConfig = new PronunciationAssessmentConfig(
referenceText: "I am tom.",
gradingSystem: GradingSystem.HundredMark,

granularity: Granularity.Word,
enableMiscue: true);
pronunciationAssessmentConfig.PhonemeAlphabet = "IPA";
pronunciationAssessmentConfig.NBestPhonemeCount = 5;

speechConfig.SetProperty(PropertyId.Speech_SegmentationSilenceTimeoutMs,3000.ToString());

using var audioConfig = AudioConfig.FromDefaultMicrophoneInput();
using (var speechRecognizer = new SpeechRecognizer(
speechConfig,
audioConfig))
{
pronunciationAssessmentConfig.ApplyTo(speechRecognizer);

var speechRecognitionResult = await speechRecognizer.RecognizeOnceAsync();

// The pronunciation assessment result as a Speech SDK object
var pronunciationAssessmentResult =
PronunciationAssessmentResult.FromResult(speechRecognitionResult);

// The pronunciation assessment result as a JSON string
var pronunciationAssessmentResultJson = speechRecognitionResult.Properties.GetProperty(PropertyId.SpeechServiceResponse_JsonResult);
return pronunciationAssessmentResult;
}
}
```

Start with the FromMic reproduction and AudioConfig.FromDefaultMicrophoneInput() on Android 11/API 30; verify whether the speech SDK's default microphone path is supported in this Godot/C# setup and capture the native error context. Done means a confirmed support diagnosis and a documented resolution or reproduction boundary.
