Need help playing sound with DirectSound

[rikkemus]

I have made a DSP program that reduces a wave file size. Now i want to be able to play it on the fly as a unpack it the new soundformat. Been trying to figure out how to play it with directsound, but havent had much luck, and resources for setting this up is sparse. Does anyone have a working example/link/tutorial, that does the following or explains how to make it. Takes a block of PCM data, for instance 256 bytes. Puts it in a buffer The audio device plays the data in the buffer without gaps. Have some trouble getting the larger picture, of how it should be set up, from reading MSDN explanation. Im all new to directx. Thx in advance
