If you use an additional digital potentiometer, isn't that the same as placing resistors to the connection, either before or after the amplifier. After all those are typically resistor bridges. So the output level on the Pi would still be the same.

I would guess that controlling the volume in the Pi, before D/A converter, would lead to smallest energy consumption needed.

Also note that the components in the connections affect the quality of the sound.
