title: How to Play a sound file on line-in (Microphone)?
body: <p>That title may be seem Ridiculous but I Have problem. I have <em><code>Service capture line-in</code></em> and, save file on system as sound file (that service didn't develop by me, and I must use that).  </p>
  
  <p>So I want to write program to select sound file (*.wav, *.mp3 or etc), and then that sound file, will be <em><code>play on Line-in (Microphone) to record as user speech</code></em>.</p>
