Do you know how to use the PWM module in the AVR? If not, you should learn that first.

You can do it this way:
Set the period for 125kHz and "scale" the ADC values so that the maximum value lies within the value of the period register. Then, supply the scaled values of the ADC to the PWM module as the duty cycle. At the PWM output, use an audio amplifier.

alexxx and moottii have posted useful links. You should go through them.

Hope this helps.
Tahmid.
