Not much information here but I will try my best, could be a problem with the cable your using between the speakers and the mp3 player, you could have a dry joint, if it's like a "hum" sound your getting it's a bad ground, without the mp3 playing plugged in tap the end of the stereo minijack cable with the speakers turned up? hear the 50hz buzz - if the interference sounds the same it's most likely a bad cable or bad connector on the speakers. I would need to either hear the interference to determine what fault it is or if you can describe it better i.e. what it sounds like.
the speakers plug/outlet is usually at the back of the computer you will have to open up the computer to check the lead attached to the rear of the input plug make sure the connection is good be sure to wear an anti static earth strap before touching anything inside your computer try cleaning your computer of dust using a fine air blower from a compressor making VERY sure that there is no MOISTURE in the air line specifically around the CPU central processing unit and your sound card dust causes static to build up in a computer causing it to overheat any many other problems hope this helps
try swapping the speakers around if the problem still persists either the speaker is faulty or the speakers plug/outlet is usually at the back of the computer you will have to open up the computer to check the lead attached to the rear of the input plug make sure the connection is good or you might have to clean the dust from your computer dust causes static which causes your computer to overheat and all sorts of problems be sure to wear an anti static earth strap before touching anything inside your computer
have you tried this control panel sounds and audio,volume,advanced,speakers select the appropriate speakers from the drop down list or click start control panel administrive tools computer managementdevice manager scroll to system devices + to expand,system speaker right click properties then select use this device (enable) try cleaning your computer of dust using a fine air blower from a compressor making VERY sure that there is no MOISTURE in the air line specifically around the CPU central processing unit and your sound card dust causes static to build up in a computer causing it to overheat any many other problems hope this helps don
wrong connection in the back of the computer? it could also be low quality sound card try plugging them into your music player see if static is still there than its the AMP on the speakers if not its crappy sound card. good luck you can try USB sound card for around 20$ on amazon.com
The static is called "line noise". It happens when there is not a lot of protection between the copper wiring that carries the signals and the outside. One way for manufacturers to save money is to put just a very thin piece of protection around the copper wires, with no insulation. Just copper wiring and a thin piece of rubber or plastic. So that is why you hear the static noise, the wires are cheaply made and cannot keep out the signals they interfere with it...hence the cheap price. Wal Mart is good about giving refunds, bring it back and get a better made system. It might cost a little more but the sound will be what you enjoy.

What sort of computer do you have? Is it a laptop or desktop? Many
laptops have this problem and it is quite widespread in laptops. The
crackling or humming noise could be a result of interference from the
mains power signal.
If it's a laptop, try running it on battery alone (take out the mains
power cord). My laptop has this kind of noise in speakers when running
on mains electrical supply, but it goes away like magic when I run it
A more long-term solution is to buy a 'Ground Loop Isolator' and insert
it between your computer and the speakers/earphones. They are quite
cheap and you could get it for under £10. It removes all static noise
and you'll hear crystal clear sound.
are you sure you have plugged in the speakers properly? maybe u inserted the cable in the wrong port or u just didnt insert the cable property. A loose connection can cause static and obviously it wont play anything. Please check.
