int channels = 4;

WaveIn waveInStream = new WaveIn();

waveInStream.DeviceNumber = 0;       //this is my device - WaveIn.GetCapabilities(0).Channels == 2  

waveInStream.WaveFormat = new WaveFormat(waveInStream.WaveFormat.SampleRate, channels); //works only when channel is 2

waveInStream.DataAvailable += new EventHandler<WaveInEventArgs>(waveInStream_DataAvailable);

waveInStream.StartRecording();
