KSPROPSETID_DirectSound3DBuffer
The KSPROPSETID_DirectSound3DBuffer property set contains all the device-specific properties that are needed to implement the IDirectSound3DBuffer interface (see the Microsoft Windows SDK documentation). Using this property set, the 3D-buffer properties that are specified by the API are passed directly between DirectSound and the WDM audio driver. This property set is handled by the KSNODETYPE_3D_EFFECTS node, which handles both the 3D-buffer and 3D-listener properties.
The property items in this set are specified by KSPROPERTY_DIRECTSOUND3DBUFFER enumeration values.
The KSPROPSETID_DirectSound3DBuffer property set contains the following properties:
KSPROPERTY_DIRECTSOUND3DBUFFER_ALL
KSPROPERTY_DIRECTSOUND3DBUFFER_CONEANGLES
KSPROPERTY_DIRECTSOUND3DBUFFER_CONEORIENTATION
KSPROPERTY_DIRECTSOUND3DBUFFER_CONEOUTSIDEVOLUME
