Am i doing some thing Wrong ?

Code

sine20Seconds = new SignalGenerator()
{
    Gain = 0.5,
    Frequency = Convert.ToDouble(freqBox1.Text)                    
};
sine20Seconds.Type = SignalGeneratorType.Square;
wo = new WaveOutEvent();
wo.Init(sine20Seconds);
wo.Play();

Answer 1

Try changing

sine20Seconds.Type = SignalGeneratorType.Triangle;

to

sine20Seconds.Type = SignalGeneratorType.Square;
