title: For microphone devices NAudio is not providing "Device Number"
body: <p>I'm using NAudio to record audio from <strong>multiple</strong> microphone devices, but the problem is, to assign the device I have to provide device number (in WaveIn object), which is unknown.  </p>
  
  <pre><code>WaveIn _waveInMicrophone = new WaveIn
                  {
                      DeviceNumber = ???,
                      WaveFormat = new WaveFormat(8000, 16, 1)
                  };
  </code></pre>
  
  <p>How to get the <strong>Device Number</strong> so that i can uniquely assign device to my WaveIn object?</p>
