Question

我使用NAudio lib创建Windows服务，从声卡中捕获音频，抛出Wasapi。但在其中一台计算机上我得到hresult = -2147024809，当我调用audioClientInterface.Initialize 这是我用来捕获的代码。

     public partial class TestRecorder : ServiceBase
        {
            private static readonly Logger _logger = LogManager.GetLogger("ServiceLogger");

            public TestRecorder()
            {
                InitializeComponent();
            }

            protected override void OnStart(string[] args)
            {
                ThreadPool.QueueUserWorkItem(x =>
                {
                    using (var rec = new Recorder())
                    {
                        rec.Start();
                        Thread.Sleep(10000);
                        rec.Stop();
                    }

                });
            }

            protected override void OnStop()
            {
            }

            internal void TestStartupAndStop(string[] args)
            {

                this.OnStart(args);
                Console.ReadLine();
                this.OnStop();
            }
        }


Here is code of Recorder.


 public class Recorder : IDisposable
    {
        private static readonly Logger _logger = LogManager.GetLogger("ServiceLogger");

        private WasapiCapture MicroCapture { get; set; }
        private WaveFileWriter Writer { get; set; }

        public Recorder()
        {
            var deviceEnum = new MMDeviceEnumerator();
            MMDevice micro = deviceEnum.GetDefaultAudioEndpoint(DataFlow.Capture, Role.Communications);
            MicroCapture = new WasapiCapture(micro);
            MicroCapture.DataAvailable += OnDataAvailible;
            Writer = new WaveFileWriter(@"C:\Temp\test.wav", MicroCapture.WaveFormat);
            _logger.Trace("Recorder is initialized");
        }


        private void OnDataAvailible(object sender, WaveInEventArgs e)
        {
            if (e.BytesRecorded > 0)
            {
                Writer.Write(e.Buffer, 0, e.BytesRecorded);
            }
        }

        public void Start()
        {
            try
            {
                MicroCapture.StartRecording();
                _logger.Trace("Recorder started");

            }
            catch (Exception ex)
            {
                _logger.Fatal(ex);
            }
        }

        public void Stop()
        {
            try
            {
                MicroCapture.StopRecording();
                _logger.Trace("Recorder stopped");
            }
            catch (Exception ex)
            {
                _logger.Fatal(ex);
            }
        }


        public void Dispose()
        {
            MicroCapture.Dispose();
            Writer.Dispose();
            _logger.Trace("Capture and writer disposed");

        }
    }

尝试安装3种不同的驱动程序。试图使用不同的格式。 NAudio发送下一个参数
audioClientInterface.Initialize发送下一个参数。

   shareMode = Shared,
                    streamFlags = None, 
                    bufferDuration = 1000000, 
                    periodicity = 0, 
                    waveFormat = 32 bit PCM: 48kHz 2 channels wBitsPerSample:32 dwChannelMask:3 subFormat:00000003-0000-0010-8000-00aa00389b71 extraSize:22, 
                    audioSessionGuid = 00000000-0000-0000-0000-000000000000

在扬声器和麦克风设置中，我选择48000 hz 16 bit。请给我一些解决这个问题的提示，我该如何调试或解决这个问题。声卡模型为VIA vt1708s，主板模型为Asus P8H61-M LX3 R2.0 IAudioClient :: IsFormatSupproted返回S_OK。

Answer 1

我通过将我的Windows服务添加到Kaspersky Antivirus应用程序的例外来确定它并且它有效。

IAudioClient :: Initialize返回（E_InvalidArg，0x80070057，-2147024809）
