IDirectSoundCapture8::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 It has been superseded by WASAPI and Audio Graphs.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 capture device object created by using CoCreateInstance. Calling this method is not required when the DirectSoundCaptureCreate8 or DirectSoundFullDuplexCreate8 function is used to create the object.
Syntax

LPCGUID pcGuidDevice

Parameters
