* Date By Reason
* ==== == ======
* 07/16/99 rodtoll Created
* 07/30/99 rodtoll Updated util functions to take GUIDs and allow for
* users to pre-create capture/playback devices and
* pass them into InitXXXXDuplex
* 08/25/99 rodtoll General Cleanup/Modifications to support new
* compression sub-system.
* 08/30/99 rodtoll Added new playback format param to sound init
* 11/12/99 rodtoll Updated full duplex test to use new abstracted recording
* and playback systems.
* rodtoll Updated to allow passing of sounddeviceconfig flags in dwflags
* parameter to init is effected by the flags specified by user
* 12/01/99 rodtoll Bug #115783 - Will always adjust volume of default device
* Updated to eliminate pointer to GUIDs.
* 01/27/2000 rodtoll Updated tests to accept buffer descriptions and play flags/priority
* 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
* 08/29/2000 rodtoll Bug #43553 and Bug #43620 - Buffer lockup handling.
* 11/16/2000 rodtoll Bug #47783 - DPVOICE: Improve debugging of failures caused by DirectSound errors.
