why do home theaters go snap, crackle, pop?

    I've tried a couple of home theaters to play my DVD movies, and both of them
    go snap, crackle, pop occasionally. This happens even if they are turned off
    or in standby mode, so long as they are still plugged in. There's some kind
    of static emitted from the speaker(s) at random times. With my first home
    theater (Coby DVD-755) it was extremely loud. With my current one (Durabrand
    HT-3917) it's usually not loud or disturbing, but still noticable. I'm
    talking like it happens maybe once every few hours, not as a regular thing,
    and the static/noise only lasts for a second or two. I've read about it and
    tried the suggestions, but it doesn't help - use a grounded outlet, and a
    different outlet/circuit for the home theater. Ideas?

    Sounds like something in your house is creating voltage
    spikes or audio frequency noise on your electrical power.

    You are probably going to have to install a power filter
    on the AC that is powering your amplifier.
