debian+phosh running on PinePhone

[buffer]

Hey all! Just thought I'd mention something I've noticed, and this might just be my unit, but who knows. When booting up the PinePhone with the latest Debian Phosh updates, it starts out by making a quiet, but noticeable, high pitched screech that persists until it's plugged in or removed from a charger for the first time after boot and makes that little "click-click" sound. I thought this might just be a weird artifact of me updating my system over and over instead of just reflashing with a new image, so I tried flashing the March 22 image to a new SD card, and it seemed to be fixed, but after updating everything to the latest version, the issue popped back up again. Not sure what's causing that, but I figured y'all might want to know.

I've definitely had that issue too! I have it across operating systems, ever since it came out of the box and I turned it on it does this.
