Remarks
This API is intended to support OEMs and app developers who want the ability to query and modify the property store associated with an audio device and publish HSA apps in the Microsoft Store. In order to use this API, you must specify the restricted audioDeviceConfiguration capability in your app package manifest. This is a restricted capability. For more information, see App capability declarations.
