    Sound card noise REALLY depends on the type and age of the said
    hardware. In a good soundcard (traditionally, Creative Sound Blaster or
    whatever they're calling it now), the noise is fairly minimal to
    nonexistant (I'm saying this purely as as a user/listener, not RNG
    expert), while on mass-market hardware such as various AC97 cards,
    especially if older or embedded into notebooks, the noise is very apparent.

    It's also very annoying that DA hardware picks up various inteferences
    from surrounding buses - on many low end system moving a mouse, resizing
    windows or accessing disk drives will produce bursts of audiable noise.
