【问题描述】：

将麦克风发送到 DirectSoundOut 不适用于此代码：

        // directsound - doesn't work
        var mic = new WaveInEvent()  DeviceNumber = 0 ;

        WaveInProvider waveInProvider = new WaveInProvider(mic);

        var dso = new DirectSoundOut(DirectSoundOut.DSDEVID_DefaultPlayback, 300);

        dso.Init(waveInProvider);
        mic.StartRecording();

        dso.Play();

但几乎相同的东西适用于 WaveOut：

        var mic = new WaveInEvent()  DeviceNumber = 0 ; 
        WaveInProvider waveInProvider = new WaveInProvider(mic);
        mic.StartRecording();
        var waveOut = new WaveOutEvent();
        waveOut.DeviceNumber = -1;
        waveOut.DesiredLatency = 300;
        waveOut.Init(waveInProvider);
        waveOut.Play();

NAudio：版本 1.8.4 操作系统：Win 10 64bit

有什么想法吗？

【参考方案1】：

是的，我遇到了同样的问题。 使用这个：

var mic = new WaveInEvent()  DeviceNumber = 0 ;

    WaveInProvider waveInProvider = new WaveInProvider(mic);

    var dso = new DirectSoundOut(DirectSoundOut.DSDEVID_DefaultPlayback, 300);

    dso.Init(waveInProvider);
    mic.StartRecording();

    dso.Play();
    while(true)
