Thank you very. I really appreciate the assistance of everyone who helped to clarify this matter. Regarding any linking errors, it's easier to either grab the .lib files from the Windows SDK and convert them with coffimplib, or use the m32mscoff switch so you can link with the SDK .lib files directly. Was already doing that (both approaches). As Adam pointed out, last bit of errors were occurring because it was a class vice an interface. Again, thank you all. Andrew

Thanks for the clarification. That actually compiles but results
in access violation at the call site which takes place after
verifying that the call to DirectSoundCreate() succeeded:
if (SUCCEEDED(sound.SetCooperativeLevel(window,
DSSCL_PRIORITY)))
{
MessageBoxA(null, "Hott Damn!!", null,
MB_ICONINFORMATION);
}
else
{
MessageBoxA(null, "Naaah Man! Dat cyaan wuk!", null,

}

If you declare extern function with wrong calling convention,
calling it can result in stack corruption.
Okay, that makes sense. Will remain mindful of that.
Once DirectSoundCreate() returns successfully, I need to call
one of the function pointers in the struct but am at a loss of
how to define it based on the interface presented.
This struct is called COM interface, D has built-in support for
them: https://dlang.org/spec/interface.html#com-interfaces
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 :(
C:\Users\edwarac\work\sound\code>build
A subdirectory or file ..\..\build already exists.

notna: It is not really necessary to put the lib in the libs
folder since it's being passed on the command line and available
in the build directory. I will place it there eventually though.
On other issue remains that I could not sort out:
Once DirectSoundCreate() returns successfully, I need to call one
of the function pointers in the struct but am at a loss of how to
define it based on the interface presented.
According the code, SetCooperativeLevel() can be called one of
two ways, either via a template[1] or directly through the second
parameter provided to and modified by SetCooperativeLevel().
I tried the two approaches below both inside and outside the
struct but neither worked.
// first approach
struct IDirectSound
{
extern(C) HRESULT SetCooperativeLevel(HWND, DWORD);
}
// second approach
alias setCooperativeLevel = HRESULT function(HWND, DWORD);
setCooperativeLevel SetCooperativeLevel;
It seemed pointless trying to recreate the template since above
attempts did not expose the function signature which is necessary
to get the template working. Any ideas?

Re: Request assistance binding to Windows dsound.{lib, dll}
Another possibility is to use -m32mscoff switch https://dlang.org/dmd-windows.html#switch-m32mscoff and use ms toolchain for linking with PSDK import libraries.
Re: Request assistance binding to Windows dsound.{lib, dll}
https://forum.dlang.org/post/kcr2vn$21i6$1...@digitalmars.com implib can work for extern(C), but is likely to fail even for them.

The above URL suggests that, on Windoze, I can create a D
compatible lib from a dll file by issuing the command:
implib /s dsound.lib dsound.dll
The following file:
sound.d
===
pragma(lib, "dsound")
struct IDirectSound{};
alias LPDIRECTSOUND = IDirectSound*;
extern(Windows) HRESULT
DirectSoundCreate(LPGUID, LPDIRECTSOUND*, LPUNKNOWN);
void main()
{
LPDIRECTSOUND directSound;
DirectSoundCreate(null, , null);
}
compiled as such:
dmd sound dsound.lib
produces the output:

Obviously I'm doing something incorrectly but I'm unable to see
it. Please shed some light.
The only thing I can see is that IDirectSound8 is improperly
declared. It is struct generated form an interface which I have
now idea of how to bind to from D:
