* File: loopback.cpp
* Content: Implements the loopback portion of the full duplex test
*
* History:
* Date By Reason
* ==== == ======
* 09/10/99 pnewson Created
* 10/25/99 rodtoll Removed lpszVoicePassword member from sessiondesc
* 10/27/99 pnewson Fix: Bug #113936 - Wizard should reset the AGC level before loopback test
* Note: this fix adds the DVCLIENTCONFIG_AUTOVOLUMERESET flag
* 10/28/99 pnewson Bug #114176 updated DVSOUNDDEVICECONFIG struct
* 11/04/99 pnewson Bug #115279 changed SendMessage to PostMessage to resolve some deadlocks
* 11/30/99 pnewson use default codec
* use devices passed to CheckAudioSetup, instead of default devices
* 12/01/99 rodtoll Added flag to cause wizard to auto-select the microphone
* 01/14/2000 rodtoll Updated with API changes
* 01/21/2000 pnewson Updated for UI revisions
* Updated to support use of loopback tests for full duplex testing
* 01/27/2000 rodtoll Updated with API changes
* 02/08/2000 rodtoll Bug #131496 - Selecting DVTHRESHOLD_DEFAULT results in voice
* never being detected
* 03/03/2000 rodtoll Updated to handle alternative gamevoice build.
* 04/19/2000 pnewson Error handling cleanup
* 04/21/2000 rodtoll Bug #32952 Does not run on Win95 GOLD w/o IE4 installed
* 06/21/2000 rodtoll Updated to use new parameters
* 06/28/2000 rodtoll Prefix Bug #38022
* 07/31/2000 rodtoll Bug #39590 - SB16 class soundcards are passing when they should fail
* Half duplex code was being ignored in mic test portion.
* 08/28/2000 masonb Voice Merge: Changed ccomutil.h to ccomutil.h
* 08/31/2000 rodtoll Bug #43804 - DVOICE: dwSensitivity structure member is confusing - should be dwThreshold
* 11/29/2000 rodtoll Bug #48348 - DPVOICE: Modify wizard to make use of DirectPlay8 as the transport.
* NOTE: Now requires a TCP/IP adapter to be present (or at least loopback)
* 02/04/2001 simonpow Bug #354859 PREfast spotted errors (PostMessage return codes incorrectly
* treated as HRESULTs)
* 04/12/2001 kareemc WINBUG #360971 - Wizard Memory Leaks
* 02/28/2002 rodtoll PREFAST was reporting issue w/lines 350 and 351. Fixed.
