Why does my PC’s speakers make a hissing sound when I plug in a USB device?

Whenever I plug in any USB device into my PC an annoying hissing sound appears in my headphones or speakers (even if I am not transferring data to or from it) , and if I start transferring data, strange and very annoying and loud screeching sounds starts coming from the headphones.

    The problem is due to static charge. Get a separate sound card. Get a cheap sound card. It would definitely be better than the integrated one. And also change the PC case if sound persists.

    I have this same problem. It happens only when I use the front USB ports, though. The back USB ports don't make the speakers hum or hiss; just the front ones. Weird. my MoBo is an Intel DGB33FB (If I recall). I use regular audio jack speakers with separate power supply, not USB speakers.

    This happens to my speakers when I connect to the internet through my Pantech UML290 modem even when they are not connected to the computer. It must be an interference issue.

    Someone with a triple E degree can probably explain this much better than I can, but it sounds like improper shielding on a USB cable (or some kind of cable) is causing magnetic interference. The strange thing about audio devices is that you can detect this distortion through the noise that's produced.

    Cell phones are another cause of magnetic interference that your speakers will more than likely pick up (because they have improper shielding on an internal or external component).

    Actually, a friend of mine (with a triple E degree) explained this to me after my 3.5 audio jack speakers made crazy noises because of their proximity to a cell phone.

    Try leaving your phone by your speakers while you listen to music or surf the web. Leave the peakers on. If it's properly shielded, you'll not hear a thing. If there's improper shielding, it'll pick up a great deal of your phone's data activity. You'll hear a variety of pulses and buzzes if so.

    try muting your line in and any else that is not in use in the sound options

    makes a big difference

    Right click on Volume icon in tray.
    Click on Sounds.
    In it check sounds for Asterisk, Exclamation, System Notification.
    Maybe some faulty sounds are assigned there..

    or try a different pen drive
    or try hooking up some other headphones or speakers to be sure if its not the sound system's fault.

    Hello, what kind of mike/speakers do you have? Are they by any chance USB powered?

      speakers are externally powered, and headphones.

    This probably isn't the case for you, but I had a similar situation. The sound would happen when I hooked up the speaker's power cord to the port on the computer. I went and got an AC adapter w/ the same rating, and got my power from a wall outlet and all feedback stopped. It would be unbearable when I had a thumb drive plugged into the front USB port, and speakers getting their power from same computer.

    Do your speakers get their power from the computer?

    do you get little shock when you touch the cabinet of your PC?, if yes then it might be a problem related to the earthing of the electricity connection in your house.

    It is a new computer. It happens with all USB ports.

    There could be multiple reasons:

    1. Too close to something
    2. Volume up too loud
    3. Bad connection

    It might the problem in your motherboard or USB ports... try to find a hardware engineer in your area and have a checkup of your motherboard...

    The wiring inside your computer might be causing interference. I would check to see if the wires are connected properly if possible.
