    Speakers making a buzzing/humming noise


    Hello! I'd really apreciate some help with this issue, as it has become quite annoying to me.

    My speakers are constantly emitting a sound which can be best described as a buzzing noise. I am fairly confident that this is electrical interference. Because of this, I have tried a ground-loop isolator to hopefully help the issue. That actually made it worse, funny enough. I'll give whatever information is needed to help you help me. My PC specs are mostly filled out in my profile/information.

    Thanks to anyone willing to help me out with this!

    Hi, forgive the obvious questions:

    Do they make this noise when not connected to your PC, and with no leads connected?

    Does the buzzing vary as you adjust the volume?



    If you only hear buzzing when connected to your PC:

    - what happens if you use analogue headphones instead?
    - have you used a different lead?

    "Do they make this noise when not connected to your PC, and with no leads connected?"
    - Nope, when not plugged in or powered on, they do not make any noise at all.

    "Does the buzzing vary as you adjust the volume?"
    - Yes. It also becomes louder when I adjust the Subwoofer's volume/intensity/boost/gain (Whatever it'd be called)

    Then regarding the rest, I havent tried connected them to anything other than my PC, actually. Mostly because due to my setup, it's quite annoying to move them and reconnect them afterwards. Also, I dont have any headphones that work with a PC. Only bluetooth ones, though my PC doesnt have a bluetooth adapter since it's custom built.

    Then the last question, im not quite sure what that means, to be honest. Sorry!

    - have you used a different lead?

    = have you tried replacing the cable/wire that you use to connect your speaker to the PC?

    Try to borrow some analogue headphones to check the noise is not coming from your PC.

    I.e. is the source your PC or leads (+speaker).

    Do you hear the buzz from your speakers if the volume setting on your PC is 0?

    Under your Microphone input properties in control panel, set gain to zero.

    I'll look into getting a replacement aux cable. I'll also see if I can find some headphones I can use.

    Also, yes, I do have the noise even when my PC's volume is 0/muted.

    Ok, so that seems to tie it down to the connection between the two, and an earthing problem.

    You appear to have separate left and right connections- do both hum, and what happens if you only connect one at a time?

    Yes, both of them hum. And I am unsure if I can only connect one side. You see, both speakers (left and right) connect to the sub-woofer. The right speaker connects with a VGA cable, while the left one connects using what I believe is auxillary. Then the subwoofer has a cord going to the PC itself, which is auxillary.

    I tried unplugging the left one (Since it was easier to unplug), and the right one was still humming.

    While typing this however, it dawned on me that this may be worth noting. The system's volume dial is set to maximum. That is just how I've been using it. (Then with application/windows volume turned down lower to compensate) Is it possible that they are humming because of that high volume? Or something similar?
