Over time I have noticed the whine more often when the PBP is charging via barrel plug or USB-C. When I unplug either, the whine often goes away.
While charging, the whine lowers volume or ceases when I move the mouse, switch tabs in the web browser, or other activity. The whine returns to "full volume" when the activity ends.
