Including the Sound Namespace

Well, it's been a while since you've needed to add any new references to one of the applications. Naturally the sound resources that you will need to use do not reside in the Direct3D namespace; you will instead need to use the Microsoft.DirectX.DirectSound namespace. For each of the examples in this chapter, you will need to add a reference to this assembly for the project, as well as add a using clause for this namespace.
