Okay, that makes sense. Will remain mindful of that.

So if I'm understanding correctly, I should be able to take this:

     DECLARE_INTERFACE_(IDirectSound, IUnknown)
     {
         // IUnknown methods
         STDMETHOD(QueryInterface)       (THIS_ REFIID, LPVOID FAR 
*) PURE;
         STDMETHOD_(ULONG,AddRef)        (THIS) PURE;
         STDMETHOD_(ULONG,Release)       (THIS) PURE;

         // IDirectSound methods
         STDMETHOD(CreateSoundBuffer)    (THIS_ LPCDSBUFFERDESC, 
LPDIRECTSOUNDBUFFER *, LPUNKNOWN) PURE;
         STDMETHOD(GetCaps)              (THIS_ LPDSCAPS) PURE;
         STDMETHOD(DuplicateSoundBuffer) (THIS_ 
LPDIRECTSOUNDBUFFER, LPDIRECTSOUNDBUFFER *) PURE;
         STDMETHOD(SetCooperativeLevel)  (THIS_ HWND, DWORD) PURE;
         STDMETHOD(Compact)              (THIS) PURE;
         STDMETHOD(GetSpeakerConfig)     (THIS_ LPDWORD) PURE;
         STDMETHOD(SetSpeakerConfig)     (THIS_ DWORD) PURE;
         STDMETHOD(Initialize)           (THIS_ LPGUID) PURE;
     };

Convert it into this:

     extern (C) class IDirectSound : IUnknown
     {
         // IUnknown methods
         HRESULT QueryInterface(const(IID)*, void**);
         uint AddRef();
         uint Release();

         // IDirectSound methods
         HRESULT CreateSoundBuffer(LPCDSBUFFERDESC, 
LPDIRECTSOUNDBUFFER*, LPUNKNOWN);
         HRESULT GetCaps(LPDSCAPS);
         HRESULT DuplicateSoundBuffer(LPDIRECTSOUNDBUFFER, 
LPDIRECTSOUNDBUFFER*);
         HRESULT SetCooperativeLevel(HWND, DWORD);
         HRESULT Compact();
         HRESULT GetSpeakerConfig(LPDWORD);
         HRESULT SetSpeakerConfig(DWORD);
         HRESULT Initialize(LPGUID);
     }

Import the correct libraries:

     import core.sys.windows.windows;
     import core.sys.windows.com;

And finally link to the lib file and I should be golden!!!

Except I'm not :(
