With amps that have automatic standby capabilities there is a combination of muting circuit AND de-energizing of the amplifier. First one, then the other. When the auto-on circuit senses a valid music signal it will reverse the process, energizing the amplifier first then disengaging the mute.
The auto-on sensing circuits draw power, but these are in the range of milliwatts.
