* Content:
* 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.
