* File: dscrecd.cpp
* Content:
* This file contains the DirectSoundCapture implementation of the
* CAudioRecordDevice abstraction.
*
* 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
*
