title: Changing master volume level
body: <p>How can I change the master volume level? Using this code</p>
  
  <pre><code>[DllImport ("winmm.dll")]
  public static extern int waveOutSetVolume (IntPtr hwo, uint dwVolume);
  
  waveOutSetVolume (IntPtr.Zero, (((uint)uint.MaxValue &amp; 0x0000ffff) | ((uint)uint.MaxValue &lt;&lt; 16)));
  </code></pre>
  
  <p>I can set the wave volume but if the master volume is too low this won't have any effect.</p>
  
  <p>Thanks for any help.</p>
