Well, I see what you mean.
I think you can find all you need about direct sound on the MSDN
(msdn.microsoft.com).
However it looks like what you really need is Media Player 7 SDK which you
can download for free from Microsoft, they have many functions there
implemented, trying to help you make windows a competitive operating system.

As far as it helps, a COM object is a class pointer that has only virtual
functions.
The first three are QueryInterface() for getting other class pointers
(inheriting from the basic one), AddRef() that says you are using a pointer,
and Release() that is called when you stop using the pointer. when no one is
using any pointer, the dll is unloaded.
To load a dll you use CoCreateInstance().
