title: Classic sound mixer
body: <p>Good day, everyone! </p>
  
  <p>I write a sound mixer and I need getting under sound device capabilities control such as I can got with windows mixer. I can manipulate general volume and mute states of mixer, but I can't gain an access to other options, for example: my system has Realtek HD Audio mixer and it makes following controls:</p>
  
  <ul>
  <li>synthesizer: volume, mute and balance control;</li>
  <li>front: volume, mute and balance control;</li>
  <li>rear: volume, mute and balance control;</li>
  <li>subwoofer: volume, mute and balance control;
  and so on.</li>
  </ul>
  
  <p>My OS is Windows XP, so I use a standard mmsystem library. it takes me to find all sound devices and to get a list controls that i can got. But list has only volume and mute controls.<br>
  What do I want to come at capabilities of sound mixer? </p>
