MovieSceneCapture: How do capture and export videos with audio?

I was looking for a free way to record and export videos that works in a bundled project and found MovieSceneCapture, and after a lot of research I managed to get it to work, but the videos are muted, I’ve tried all the audio capture protocols but not got it, could someone help me? I need this for my work with Virtual Production and Composure I plan to provide a tutorial on how to use MovieSceneCapture if I can.

My Code:

 bool UBpsFuncLibrary::StartCapture(UCustomMovieSceneCapture*& MovieSceneCapture,
     FMovieSceneCaptureSettings MovieSettings,
     TSubclassOf<UMovieSceneImageCaptureProtocolBase> ImageProtocol,
     TSubclassOf<UMovieSceneAudioCaptureProtocolBase> AudioProtocol)
 {
     UCustomMovieSceneCapture* MovieCapture = NewObject<UCustomMovieSceneCapture>();
     TSharedPtr<FSceneViewport> SceneViewport;
     // Get Scene Viewport
     if (GEngine->GameViewport && GEngine->GameViewport->GetGameViewportWidget())
     {
         SceneViewport = MakeShareable(new FSceneViewport( GEngine->GameViewport, GEngine->GameViewport->GetGameViewportWidget() ));
     }
     if (MovieCapture)
     {
         if (ImageProtocol)
         {
             MovieCapture->SetImageCaptureProtocolType(ImageProtocol);
         }
         if (AudioProtocol)
         {
             MovieCapture->SetAudioCaptureProtocolType(AudioProtocol);
         }
         MovieCapture->Settings = MovieSettings; 
         MovieCapture->Initialize(SceneViewport,0);
         MovieCapture->StartWarmup();
         MovieCapture->StartCapture();
         MovieSceneCapture = MovieCapture;
         return true;
     }
     return false;
 }
 
 bool UBpsFuncLibrary::FinishCapture(UCustomMovieSceneCapture* MovieCapture, bool ForceFinish)
 {
     if(MovieCapture)
     {
         (ForceFinish) ? MovieCapture->Finalize(), MovieCapture->Close() : MovieCapture->FinalizeWhenReady();
         return true;
     }
     return false;
 }
