Erm... if the volume control scaling is not linear (not using same size steps as the DAC), does that not make it possible to get better than 14 bit result? (Or worse for that matter.)
I.e. smallest sample value (well, isn't it the difference between two values really?) at full volume is louder than the biggest sample value at minimum volume?
ISTR that I did some tuning for a 14-bit playback thing that involved turning up the stereo something scary.

Reason: step size
