    you can't be sure unless you test it. There are 2 types of bad grounds:

    one is a failure to ground to a field (such as the earth or a power grid)

    the second is a short to ground

    I't's not worth it to me

    I used to design and build my own PSU & amplifiers and stuff, but with todays prices it just isn't worth it anymore to go and find out what went wrong inside & repair it.
    In a speaker-set everything is integrated, like on mobo's, many components exist out of SMDs, the tiny blocks on your board are SMDs, those can be a capacitor, or a resistor, a transistor, whatever, any component you can imagine.
    It's very hard to go change them yourself 'cause in the manufactering process they're damped on the circuitboard, also not many of them can stand the high temperature when welding.
    And as he found out his speakers failed, everything else was working fine appearantly.
    So prob solved :approve:

    mazchaz - the symptom you are describing is common. the only times people complain about it being noticeable is when they have improper volume settings. this problem usually occurrs most with cheaper sound cards or integrated ones.

    your volume in windows should be set all the way up, and you should be controlling your volume from the powered speakers.
