    Speaker wire Plugging In or Moving


    I tried googling this but couldn't find an answer. I have male to male speaker wire 3.5 connection. I always wondered why when you plugin the speaker wire in the back of the computer (my sound card is in the back) it cracks or pops. Once it is plugged in - no noise - unless you move the speaker wire and then you get the same cracking or popping noise.

    So as long as the speaker wire isn't moved after you plug it in to the sound card, all is ok - no cracking. But if I'm fiddling around with my connections on the back of my computer and move the speaker it makes the noise. Is this a defect or normal?

    Thanks

    I'm an ex guitar amp tech.
    If you plug in with the speaker powered on there can be "noise" when its first plugged in.
    Moving the speaker wire (or wiggling) the plugs says either a bad internal wire to plug connection or if wiggling the plug in the PC sound jack says possible dirty connection. If its the cable, replace the speaker wire(s) between the PC and speaker. If its the connection usually spraying the female PC jack and maybe the male plug with contact cleaner usually fixes it., However if its just the noise when you plug in, that is normal as long as it works OK after plugged in.

    Yep, I fix computers for folks and see the same thing. Also just touching the metal part of a plug can cause noise, probably static electricity in ones body. Touching the tip of the plug to the computer case can also make noise. A lot depends on the speakers having power and being turned on even though not plugged into a speaker port.
