IDirectSound8::Initialize Method
[The feature associated with this page, DirectSound, is a legacy feature. It has been superseded by WASAPI and Audio Graphs. Media Casting have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use Media Casting instead of DirectSound, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The Initialize method initializes a device object that was created by using the CoCreateInstance function.
Syntax
HRESULT Initialize(
LPCGUID pcGuidDevice
)
Parameters
- pcGuidDevice
Address of the globally unique identifier (GUID) specifying the sound driver to which this device object binds. Pass NULL to select the primary sound driver.
Return Value
If the method succeeds, the return value is DS_OK. If the method fails, the return value may be one of the error values shown in the following table.
| Return code |
| DSERR_ALREADYINITIALIZED |
| DSERR_GENERIC |
| DSERR_INVALIDPARAM |
| DSERR_NODRIVER |
Remarks
This method is provided for compliance with the Component Object Model (COM) protocol. If the DirectSoundCreate8 function was used to create the device object, this method returns DSERR_ALREADYINITIALIZED. If IDirectSound8::Initialize is not called when using CoCreateInstance to create the device object, any method called afterward returns DSERR_UNINITIALIZED.
