* File: fulldup.cpp
* Content: Implements a process that uses DirectSound and
* DirectSoundCapture to test the systems full duplex
* capability. Note that WinMain is in fdtest.cpp, but
* the guts are here.
* History:
* Date By Reason
* ============
* 08/19/99 pnewson created
* 10/28/99 pnewson Bug #113937 audible clicking during full duplex test
* 11/02/99 pnewson Fix: Bug #116365 - using wrong DSBUFFERDESC
* 01/21/2000 pnewson Changed over to using a dpvoice loopback session
* for full duplex testing
* 04/19/2000 pnewson Error handling cleanup
* 07/12/2000 rodtoll Bug #31468 - Add diagnostic spew to logfile to show what is failing the HW Wizard
