User's Guide
============
  Load a wave file by clicking Sound File. Select Focus and Buffer Mixing 
  options; note that the various settings are explained under Expected Behavior 
  as you select them. Click Play. If you don't hear any sound, check the Status 
  pane. The application might fail to create the buffer in hardware if this 
  option has been selected. 

  By using the sliders you can adjust the frequency, pan, and volume dynamically 
  as the buffer is playing.

Programming Notes
=================
  For a simpler example of how to setup a DirectSound buffer without as many 
  controls, see the PlaySound sample. 
  
  To set the focus of a buffer call IDirectSound::CreateSoundBuffer with 
  DSBCAPS_GLOBALFOCUS or DSBCAPS_STICKYFOCUS or neither of these flags. 
    
  To set the memory location of a buffer call IDirectSound::CreateSoundBuffer 
  with DSBCAPS_LOCHARDWARE or DSBCAPS_LOCSOFTWARE or neither of these flags. 
    
  To control various aspects of DirectSound buffer:
    To adjust the frequency call IDirectSoundBuffer::SetFrequency
    To adjust the pan call IDirectSoundBuffer::SetPan
    To adjust the volume call IDirectSoundBuffer::SetVolume
