I don't know if BIOS-level services will actually permit you to access the speaker under Win9x/WinNT; FPW uses the currently defined sound device, as does VFP.

While it will not be difficult to write code to control for the DOS platform (for FPDOS, you can create a .BIN file with an assembler (essentially, it's loaded into memory as machine code) or using the Library Construction Kit, write a .PLB in the correct flavor of C (Watcom), a .PLB to do it) it's probably not a smart thing to do, since BIOS-level access is going to be very timing dependent, and in a Windows environment you are likely to not have adequate control over when your application is running. And then realize that the DOS platform has no understanding of the .WAV file, so you'll have to write something to decode the .WAV file and control the output yourself.

Is there some reason not to use the default Windows sound device?
