XAudio2Create (CoCreateInstance) returning undocumented error. How do I fix?

I've been working on a sound engine using XAudio2.

On my development computer everything works.
(AMD FX08350, with a Sound Blaster X-Fi Xtreme Audio card, running Windows 7 64-bit and using DirectX 11. Code::Blocks, TDM MinGW, and DirectX SDK installed.)

When I move the program to a different computer (Intel core i5-3470, on-board sound card, running Windows 7 64-bit and using DirectX 11) I get an HRESULT of 0xFB06A210 from XAudio2Create (which redirects to CoCreateInstance).

Looking at HRESULT, this has an S,R,C,N,and r of 1, a Facility of 0x0306, and a code of A210. I can't find any information on what this means or how to get XAudio2 to work on the test computer?

Can anyone help me?

you may search for the class id passed to CoCreateInstance in your local registry (probably below HKLM\Software\Wow6432Node). if there are entries, you could check whether those entries also exist on the second computer.

also check event viewer (eventvwr) whether there is more information when the error occurred.
