The KSPROPSETID_AudioEngine property set contains KS properties that the audio driver can use to provide more information about the hardware audio engine node.
KSPROPSETID_AudioEngine is available with Windows 8 and later versions of the Windows operating system.
When a hardware solution supports audio offloading, the audio driver for the hardware must expose its capabilities in a specific manner so that the Windows 8 user-mode audio stack can discover these capabilities and take advantage of them.
To support the audio offloading architecture provided with Windows 8, the hardware solution must implement a hardware audio engine. The audio driver for this hardware must then expose the hardware audio engine as an audio engine kernel streaming (KS) node that is contained within a KS filter. The node type that has been newly defined for this purpose is KSNODETYPE_AUDIO_ENGINE. The KSPROPERTY_AUDIOENGINE enumeration is used to represent the new KS properties.
The Ksmedia.h header file defines the KSPROPSETID_AudioEngine property set as follows:
#define STATIC_KSPROPSETID_AudioEngine\ 0x3A2F82DCL, 0x886F, 0x4BAA, 0x9E, 0xB4, 0x8, 0x2B, 0x90, 0x25, 0xC5, 0x36 DEFINE_GUIDSTRUCT("3A2F82DC-886F-4BAA-9EB4-082B9025C536", KSPROPSETID_AudioEngine); #define KSPROPSETID_AudioEngine DEFINE_GUIDNAMED(KSPROPSETID_AudioEngine)
The KSPROPSETID_AudioEngine property set contains the following KS properties.
These property names are defined in the KSPROPERTY_AUDIOENGINE enum.
