multichannel audio with directX

[Franken]

Hi everybody, I'm going to write a multichannel audio application with directX under VC++ 6. I know that for using multichannel I have to use the WAVEFORMATEXTENSIBLE structure instead of WAVEFORMATEX. This structure is supposed to be declared in mmreg.h, unfortunately not in my version of this header file. I have VC servicepack 6 and dx90bsdk installed on my computer. Do I make a silly mistake or does anybody else encountered this problem? Can anybody tell me where I can get the correct mmreg.h? Thanks for your help, Frank.
