I can confirm a different noise with/without USB plugged in.

Just noticing this for the first time, here's some additional testing and observations related to my case.

  1. On battery power, very very light high pitched noise.  Barely perceptible(ear on keyboard)
  2. Plug in USB-A(yubikey), volume increases to a noticeable level.
  3. Plug in barrel jack with USB-A.  Volume increases more.
  4. Swap to USB-C. Same volume as 3.
  5. Tried another power supply for barrel and USB-C, as well as another USB-C cable.  No notable changes, same as 3, 4
  6. All tests, with Manjaro running from SD.  Being the first time I've noticed it and the first time not using the stock OS, I switched back and tested again.
  7. All prior tests produced no perceptible noise when running stock Debian from eMMC.
