It's not a big deal, but with new update, for some players game show error that X3DAudio1_7.dll is missing when they start game.

I've replaced DirectSound with XAudio.
I'm not aware of a fix for this, except:

or bundling the DLL with your game.

You could always revert back to DirectSound:
make changes in headers.h to:
#define DIRECT_SOUND WINDOWS_OLD
#define XAUDIO WINDOWS_NEW

There are other versions but they don't support Win7
