Help with clAmdFft

Hi. I have written a code for computing several 1d ffts using the clAmdFft libraries. My code compiles and "works" but I can only get correct results for ffts of constants functions. Whenever I put a sinus or a linear function, I got a really really noisy fft (secondary waves of 30% of amplitude at least when I do the inverse fft with matlab); however I'm unable to find any error.

Any source of help/tip would be great.
