Moving my cursor makes an audible sound over my (builtin) audio card. I always blamed inductors somewhere (noisy power). This has never not been the case with any desktop with built-in audio I have owned over the past 25+ years

For your next desktop, get a motherboard with an optical audio output. Or add a soundcard with that for your current computer, those are still made.

Optical is a great suggestion! Never used it after 1998~ on my minidisc.
