I have a Dell Inspiron 1505 Laptop and there is a loud static noise that comes from the speakers. It is not constant, just intermittent, but still is loud enough that i can't use the computer. I have had a Dell rep change the speakers and that stopped the problem for a while but it has now resurfaced. I am running Windows Vista 32-bit. Also, when i checked the speakers and microphone jacks, the volume meter on the microphone jack shows that a sound is being recorded by the microphone every time the static sound is made. It causes the volume meter on the microphone to be maxed out so i'm not sure if this has something to do with the problem.

If the numlock key is not working at all, try to tear down your laptop by removing the keyboard itself out from your laptop. But if your hesitating to do that, just simply call DELL technical support for assistance and in a case that the numlock is not totally working at all, then they can able to replace the keyboard or the motherboard, depending on the troubleshooting that could be done. Make sure that your laptop still under warranty coz if not then it is required for you to buy a keyboard that fits for your Inspiron 1505. And if in a case that bad is the motherboard, then it should be replace. Thank you.
things can cause static.
If you have your speakers turned up to high it will give you feedback causing
distortion and static. I recommend using a headset when videoing.
reason is, if you are using a laptop and have added an external microphone
between the two it will cause distortion and static.
knowing the configuration of your computer makes it harder to analyze the
hope this is of some help. Bud
Please try moving the laptop to another location, if you have not already tried that, especially if you have any other electromagnetic device nearby (like a transformer, motorized device, machinery, etc...)
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.
