Well, I am overwriting the buffers, that's the ideia right, allocating an array of buffers and creating the wave sine and holding them in this array? This buffer is never written over latter in the program (ie: This function is called only once) Is there any other way for making this?
Also, I'm using Linux, and I've tested this on both M-Audio Audiophile USB interface and a common nForce audio board (the one on board on some mother boards), the results are the same.

My only real comment here is that you seem to be leaking buffers. You create
an array of them here:

Then overwrite/leak the handles in the following loop:

As for the static.. what OS and lib version are you using? What's your sound
card?
