DirectSound Component GUIDs

[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 It has been superseded by WASAPI and Audio Graphs.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 following GUIDS are used as class identifiers (CLSIDs) in the creation of DirectSound components.

CLSID	Component
CLSID_DirectSound	DirectSound playback device
CLSID_DirectSound8	DirectSound8 playback device
CLSID_DirectSoundCapture	DirectSoundCapture device
CLSID_DirectSoundCapture8	DirectSoundCapture8 device
CLSID_DirectSoundFullDuplex	Full duplex device

Note

For information about the differences between the older and newer versions of playback and capture device components, see IDirectSound8 Interface and IDirectSoundCapture8::CreateCaptureBuffer.
