    I don't know how else to describe it, but when I turn up my
speakers enough (50%+) and don't have any sound playing, I hear a
whitenoise hiss coming out of them. When I change webpages (nvidia
driver is GIANT locked) or do something else kernel intensive it stops
for a brief second, but apart from that it's an annoying trill sound
almost like a mosquito humming around me waiting to be swatted.
    It's really driving me insane... Hopefully helpful snippets follow:

    vendor     = 'Intel Corporation'
    device     = '82801IB/IR/IH (ICH9 Family) HD Audio Controller'
    class      = multimedia
    subclass   = HDA
