 *		This module contains the implementation of the 
 *		CDirectSoundPlaybackDevice.
 *
 *  History:
 *   Date		By		Reason
 *   ====		==		======
 * 07/16/99		rodtoll	Created
 * 07/30/99		rodtoll	Updated to allow creation of object using a pre-created
 *						DirectSound Object.
 * 10/05/99		rodtoll	Added DPF_MODNAMEs         
 * 10/14/99		rodtoll	Added 3d caps to primary buffer created
 * 10/27/99		rodtoll	Bug #115431: Must release primary buffer
 * 11/12/99		rodtoll	Modified abstraction for new waveOut support.
 *						Now abstracted types look almost like dsound objects   
 * 12/01/99		rodtoll Bug #121815 - Static in playback/record
 *						Added implementations of Set/GetMixerQuality
 *						(For Win2k/Millenium/Systems w/DX7) 
 * 01/27/2000	rodtoll	Updated sound classes to accept playback flags, 
 *						buffer structures and DSBUFFERDESC instead of DSBUFFERDESC1 
 * 02/16/2000	rodtoll	Fixed so primary buffer is not released
 * 02/17/2000	rodtoll	Updated so primary buffer is held instead of released immediately 
 * 04/21/2000   rodtoll Bug #32952 - Does not run on Win95 GOLD w/o IE4 -- modified
 *                      to allow reads of REG_BINARY when expecting REG_DWORD 
 * 04/24/2000   rodtoll Bug #33203 - Removed workaround for aureal vortex 1 problem -- had 
 *                      problems on Vortex 2.  
 *  06/09/00    rmt     Updates to split CLSID and allow whistler compat and support external create funcs 
 * 07/12/2000	rodtoll	Bug #31468 - Add diagnostic spew to logfile to show what is failing the HW Wizard
 * 08/03/2000	rodtoll	Bug #41457 - DPVOICE: need way to discover which specific dsound call failed when returning DVERR_SOUNDINITFAILURE 
 *  08/28/2000	masonb  Voice Merge: Changed ccomutil.h to comutil.h
 * 04/04/2001	rodtoll	WINBUG #343428 - DPVOICE:  Voice wizard's playback is very choppy.
