Charging via barrel jack = audible high pitched coil whine.
Charging via USB-C = completely inaudible coil whine.

Not sure why the difference. Something to do with USB-C PD? ¯\_(ツ)_/¯

Do you get it running off battery power with no charger?

I've found that I get the high pitch whine when a USB-A peripheral (such as a mouse) is plugged in.
