The IKsPropertySet interface allows drivers to provide extended capabilities that can be used without API extensions. DirectSound supports this interface for accessing properties of sound drivers.
The IKsPropertySet interface is part of the WDM KS (Win32® driver model kernel streaming) architecture.
To retrieve this interface, call the QueryInterface method of any interface on a DirectSound buffer.
In addition to the methods inherited from IUnknown, the IKsPropertySet interface exposes the following methods.
| Method | Description |
| Get | Retrieves data for an item in a property set. |
| QuerySupport | Ascertains whether a property in a property set is supported on the port or device. |
| Set | Sets the value of a property in a property set. |
