  • subwoofer buzzes when games run, even on mute?

    Hi
    I plugged a subwoofer into my PC, and noticed two things -
    Any time I move my mouse in windows, or even in UEFI bios, it makes a noise until I stop.
    When I load a game or even put OCCT power test (cpu+gpu) it starts to buzz loudly.
    This shows what I mean : Video0137 - YouTube
    Notice that every time I move my mouse in the game the noise is different.
    It doesn't matter if I mute the sound on the pc!! It will still happen.

    So I tried-
    -plugging on front and rear panel
    -plugging instead of main speakers
    -changing audio and power wires
    -changing outlets
    -turning off all the electricity in my house except my room, in case it's a ground problem
    -disconnecting everything but power,speakers,monitor from pc
    -didn't bother changing drivers as I have the problem when I move the mouse even on BIOS.
    -checking for inflated capacitors inside the subwoofer
    -enabling spread spectrum, even restore all bios defaults
    -This happens even if I plug the subwoofer as mic/line in (and leave it as mic/line in at the driver)

    I was using this sub before with another PC without problems . Couldn't check with tv/phone or something because the problem is just on PC load.

    3570K, Asus P8Z77V-PRO (not thunderbolt), no noise on my speakers and 2 generic headphones

    Please help me out !
    Thanks

    Have you tried connecting your mouse to different ports?
    Can you test with a different mouse?
    What is the brand name and model number of your mouse?

        sounds like a ground loop on the subwoofer line. Is this a powered subwoofer? if so make sure its plugged into the same plug as the computer. a second option is to install a line-level isolator on the line in cable
