Mouse interferes with sound

    Mouse interferes with sound

    Does anyone know why moving the mouse generates sound from my
    speaker? It's a slight ringing noise, it has happened to me on every
    version of Windows since 2000, probably before that as well, and it's
    horribly annoying. It's even worse when I use the mouse to drag a
    scrollbar or a window. Since I've never had a windows installation
    where this DIDN'T happen, I'm assuming it's a global problem and
    others have experienced this as well. If you don't know what I'm
    talking about turn the volume on your speakers way up and then move
    the mouse around.

    If anyone knows how to get rid of this I would really appreciate it.

    Re: Mouse interferes with sound

    It's called radio interference and you get rid of it by placing your
    speakers *well* away from the PC. I've got a fairly loud static, anyway,
    because the base woofer cabinet is practically leaning against my tower. If
    I turn my speakers way up, the small battery powered clock that's 6' away
    from the desk can be heard tick-tocking. Probably doesn't help that I have
    an Army surplus steel desk.

    Mine's a wired mouse, currently. Perhaps a wireless mouse would help the
    problem. Or perhaps it would be worse.

    This can be an issue with on-board audio, especially with earlier
    motherboards. If you have on-board audio, the best solution is
    to get a PCI sound card. This is usually not a problem on recent
    motherboards with on-board multi-channel HD audio.

    I'll ask you, too. What makes onboard sound different than a PCI card in
    this respect?

    The noise problem with on board sound is only audible at high
    amplification settings, and most noticeable when no other sound
    is being generated. On board sound codecs rely on the CPU for
    processing and are tightly integrated into the motherboard circuitry,
    and subjected to electrical noise, especially on the v+ line. A lot of
    the noise is generated by changes in processing load caused by
    interrupts. Most interrupt noise is high frequency and random,
    and blends into the normal backgroung hiss. A moving mouse
    generates a stream of repetitive interrupts in the audible range,
    the effects of which can be clearly heard when the volume is set
    high. It's the mouse generated noise that is the cause of complaints.

    The PCI bus is more electrically isolated from CPU activity. Also,
    most quality PCI sound cards do their own on card hardware sound
    processing, and have additional filtering on the power connections.
