I'd like to not one thing, namely, you are using FPU to generate the samples. This is something Fabrice expressed dissatisfaction with. In the case of speaker it might be feasible to switch to fixed-point calculation.
One more note about that. PC-speaker generates just plain square wave not sine wave, so this would be more realistic. Then fixed point calculation (16 bit integer part and 16 bit fractional) is easy without all those sin calculation.
