HRESULT Initialize(
  LPCGUID pCaptureGuid,
  LPCGUID pRenderGuid ,
  LPCDSCBUFFERDESC lpDscBufferDesc ,
  LPCDSBUFFERDESC lpDsBufferDesc,
  HWND hWnd ,
  DWORD dwLevel ,
  LPLPDIRECTSOUNDCAPTUREBUFFER8 lplpDirectSoundCaptureBuffer8 ,
  LPLPDIRECTSOUNDBUFFER8 lplpDirectSoundBuffer8
);

Parameters

pCaptureGuid

Address of the GUID that identifies the sound capture device for full duplex input. Must be one of the GUIDs returned by DirectSoundCaptureEnumerate, NULL for the default capture device, or one of the values shown in the following table.

Value	Description
DSDEVID_DefaultCapture	System-wide default audio capture device.
DSDEVID_DefaultVoiceCapture	Default voice capture device.

pRenderGuid

Address of the GUID that identifies the sound rendering device for full-duplex output. Must be one of the GUIDs returned by DirectSoundEnumerate, NULL for the default rendering device, or one of the values shown in the following table.

Value	Description
DSDEVID_DefaultPlayback	System-wide default audio playback device.
DSDEVID_DefaultVoicePlayback	Default voice playback device.

lpDscBufferDesc

Address of a DSCBUFFERDESC structure that specifies the characteristics of the capture buffer.

lpDsBufferDesc

Address of a DSBUFFERDESC structure that specifies the characteristics of the render buffer.

hWnd

Handle to the application window.

dwLevel

Cooperative level for the device. For more information, see SetCooperativeLevel.

lplpDirectSoundCaptureBuffer8

Address of a variable that receives the IDirectSoundCaptureBuffer8 interface of the capture buffer.

lplpDirectSoundBuffer8

Address of a variable that receives the IDirectSoundBuffer8 interface of the render buffer.

Return Values

If the method succeeds, the return value is DS_OK.

If it fails, the return value may be one of the values shown in the following table.
