Interpretation Sin(2*pi*f*t) in matlab for producing sound

Hello everyone, I am required to produce wave sound files for a given data which contains information about the sound pressure and frequency. I use the equation y = A sin(2*pi*f*t) to produce sound. I am using sound pressure as amplitude. What's strange is that when I produce the sound using this method, I am getting frequency components which are exactly double the original frequency value. When I remove the 2 from the Sin(2*pi*f*t), its working! I get the exact frequency when I perform a fft transform on the wave file. Do any of you have an explanantion for this??

Not without seeing the rest of your code.
