The IDirectSound::Initializemethod initializes the DirectSound object that was created by using the CoCreateInstancefunction.

HRESULT Initialize(
LPGUID
lpGuid
);

Parameters

lpGuid

Address of the globally unique identifier (GUID) specifying the sound driver to which this DirectSound object binds. Pass NULL to select the primary sound driver.

If the method succeeds, the return value is DS_OK.

If the method fails, the return value may be one of the following error values:

DSERR_ALREADYINITIALIZED

DSERR_GENERIC

DSERR_INVALIDPARAM

DSERR_NODRIVER

Remarks

This method is provided for compliance with the Component Object Model (COM) protocol. If the DirectSoundCreatefunction was used to create the DirectSound object, this method returns DSERR_ALREADYINITIALIZED. If IDirectSound::Initializeis not called when using CoCreateInstanceto create the DirectSound object, any method called afterward returns DSERR_UNINITIALIZED.

On Windows CE, CoCreateInstancecannot be use to create the DirectSound object on CE. DirectSoundCreateshould be used instead. This method always returns DSERR_ALREADY_INITIALIZED.
