my focusrite scarlett 2i2 has started buzzing. grr.
i am powering it via probably the shittiest possible usb-c cable. i wonder if getting a better cable would fix it.

adding a powered usb hub did not fix it. so i modified a usb cable to let me splice in power from an external 5v psu.

*that* fixed it.

this is a *server motherboard* ASRock. what are you even doing. why is there noise on the USB power rails.
@ariadne You sure it wasn't a ground loop ? :0
@theodora yes. 100% positive. my power is clean, i have three-phase service
