I am using a microchip microcontroller to read in a 8ks 16 bit .wav file
and output it through the dac.  I have a small 109 dB speaker 32 ohm
impedance, nominal input power of 12mW and max input power of 20mW for 1
minute.

I haven't done anything like this in years.  I don't want volume control
just the loudest possible.  How do I limit the power going to the speaker?
Can anyone point me in a direction?
