I really think it is an aliasing problem.

even when i output a single 440hz sine i get harmonics starting at

to nyquist and beyond.
Lemme guess your wavetable size is 256? That's the amount of
distortion that would be expected from using "no interpolation". If
that's what you have then the codec is not at fault.
i use code similar to what RBJ has posted with linear interpolation
(although with a tablesize of 256 at the moment).
