 *  History:
 *   Date		By		Reason
 *   ====		==		======
 * 11/04/99		rodtoll	Created
 * 11/12/99		rodtoll	Modified abstraction for new waveIN support.
 *						Now abstracted types look almost like dsoundcap objects  
 * 11/22/99		rodtoll	Added code to map from GUID to waveIN device
 *						ID for non-millenium systems.
 * 11/23/99		rodtoll Updated to use waveIn device ID or DSound 7.1 when they are avail 
 * 12/01/99		rodtoll	Bug #115783 - Will always adjust volume of default device
 *						Now uses new CMixerLine class for adjusting volumes/selecting mic 
 *				rodtoll	New algorithm to map from GUIDs to device IDs if DSound 7.1 is not
 *						available.  Will map device correctly on DX7, will guess for other
 *						DX versions < 7.  However, default device is assumed to be waveIN ID #0. 
 * 12/08/99		rodtoll Bug #121054 - DirectX 7.1 support.  
 *						- Added hwndOwner param for capture focus support 
 * 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 
 *  06/09/00    rmt     Updates to split CLSID and allow whistler compat and support external create funcs 
 * 06/28/2000	rodtoll	Prefix Bug #38022
 * 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
 * 09/13/2000	rodtoll	Bug #44806 - When volume control not avail, dropping to DX7 levels instead of disabling volume control
