* 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
|
||
|

|
||
|
|
* 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.
|
||
|
