Can't play sound from array with RAW data

From this topic : http://forums.ni.com/t5/LabWindows-CVI/I-want-Example-FM-Receiver-for-RFSP-on-CVI-please/m-p/2811486

I can demodulate the signal that came from IQ data using Modulation Toolkit and collect message data in array.

then I export message array to txt file in ASCII format using ArrayToFile function and i can play it correctly in MATLAB by using sound command.

Finally , I try to play message signal directly through soundcard without using MATLAB but i'can't .

I try to learn in example in this forum [Ex. sndplay , CVIDsound etc. ]  but i can't fix it

CVIDsound is look pretty good but it is so complicate , i can't find the way to send my message array to play with Dsound.

Can you keep me the simple example to using Dsound or guide me to use it.
