The SetAllParameters method sets all 3-D sound buffer properties.
Syntax
HRESULT SetAllParameters(
  LPCDS3DBUFFER pcDs3dBuffer, 
  DWORD dwApply 
);
Parameters
pcDs3dBuffer
Address of a DS3DBUFFER structure that describes the 3-D characteristics of the sound buffer.
dwApply
Value that specifies when the setting should be applied. This value must be one of the following:
| Value | Description | 
| DS3D_DEFERRED | Settings are not applied until the application calls the IDirectSound3DListener8::CommitDeferredSettings method. This allows the application to change several settings and generate a single recalculation. | 
| DS3D_IMMEDIATE | Settings are applied immediately, causing the system to recalculate the 3-D coordinates for all 3-D sound buffers. | 
Return Values
If the method succeeds, the return value is DS_OK.
If the method fails, the return value may be DSERR_INVALIDPARAM.
