 *  08/12/99	rodtoll	created it
 *	08/19/99	rodtoll	Updated lobby launching to support retrofit
 *  08/20/99	rodtoll	Modified to respond to shutdown request and
 *						do proper lobby launch when in client mode.
 *	08/25/99	rodtoll	Updated to use new GUID based compression selection
 *  09/14/99	rodtoll	Updated for new Init call and SoundDeviceInfo usage.
 *  09/27(8)/99 rodtoll	Updated with new interface
 *  09/28/99	rodtoll	Updated for structure changes.
 *  09/29/99	rodtoll	Updated for async enum, fixed bug with lobby launch
 *  10/15/99	rodtoll	Massive code cleanup.  Split into multiple files
 *				rodtoll	Minor fix, event was being released twice
 *  10/20/99	rodtoll	Fixed name info for helper app
 *  11/02/99	rodtoll	Bug #116677 - Can't use lobby clients that don't hang around
 *  11/04/99	pnewson Bug #115297 - launch device test if required
 *  11/12/99	rodtoll	Added support for the new waveIN/waveOut flags and the 
 *					    echo suppression flag. (Can specify them on command-line)
 *  12/01/99	rodtoll	Bug #115783 - Regardless of device specified always adjusts volume
 *						for default.  Modified dpvhelp to allow user to select play/record
 *						devices by using /SS switch.
 *  12/07/99	rodtoll	Bug #122628 Make error messages silent when running in silent mode
 *				rodtoll	Bug #122979 Make invisible to end user
 *						Now app must be run with /A to show an interface.
 *						Also, unless /A or /L or /W are specified, the app will exit immediately.
 *						Command-line help removed.
 *						Auto-registration code removed for public version of app.
 *  02/15/2000	rodtoll	Bug #132715 Voice is not working after rejoining the session
 *  03/03/2000	rodtoll	Updated to handle alternative gamevoice build.   
 *  06/28/2000	rodtoll	Prefix Bug #38033
