At the time I press the power button to turn the system on or when the system completes its shutdown, there is an audible pop or crackle heard. It is not terribly loud, but does bring up concern about DC getting to the internal speaker from which the sound originates. It does not seem to matter if the internal speaker is enabled in SW. Is this notable behavior, or exhibited in all of the systems?

The is a result of the voltage decay in the audio amplifier and is not anything of concern.
