title: How to know if a sound is playing using c#?
body: <p>I have a TTS program (Third Party) and I wrote a c# application that uses that program. (Type into my application and press a button to move the mouse and click on the Third party app).</p>
  
  <p>I need to know whether the speech is finished or not. Are there any ideas on how to determine if any sound playing from sound card or not?</p>
