Application works in visual studio but release/debug exe does not

问题

I am making a game using dx11. When I compile and run the code in visual studio it works fine however if I try and run the code from the .exe file in either the debug or release folders I got the following error:

"Could not initialize direct sound"

I have not moved the folders/directories at all.

Is this something to do with direct sound not being compatible with dx11? If so why would it still run inside visual studio.

I am using MS Visual Studio 10. My direct sound class has the following:

#pragma comment(lib, "dsound.lib")
#pragma comment(lib, "dxguid.lib")
#pragma comment(lib, "winmm.lib")
#include <windows.h>
#include <mmsystem.h>
#include <dsound.h>
#include <stdio.h>

Advance Thanks
