Mic only producing static noise

it might be because of rays emitted by the monitor...show it to your local electrical equipment repairer or take it to the service centre if still in warranty

Bad capacitors possibly?

That means that if too much power is going to the speaker or extraneous signals are being picked up by the wiring, it can come through the speakers as static. Stopping static requires finding and eliminating that extra electricity from transmitting through your speakers.
If you're still hearing distortion, turn down the volume on your amplifier until the distortion goes away. If the volume is too low to be easily heard, the problem may be that your amplifier produces too much power for your speakers to handle or that your amp and speakers have different impedance ratings.

Need to re install the sound drivers

Make sure that there is no fault inthe connection from the line terminals. If both the sets have the same noise connect a base phone and test the line as it can be from the telphone line itself producing the static from the nearest junction or cable line.
If not the base phone input section may have errors.

I had this on some Acer TravelMate 4220. Ours turned out to be the mic turned on and way up. Turning the mic off or all the way down fixed it.

you need a ground loop isolator or some way to ground the laptop/power supply to remove the noise. the noise is electrical interference produced by the inverter.

Normal 0 Two things can cause static.
First, If you have your speakers turned up to high it will give you feedback causing distortion and static. Best to use headphones when recording.
Second reason is, if you are using a laptop and have added an external microphone between the two it will cause distortion and static.
Not knowing the configuration of your computer makes it harder to analyze the problem.
So hope this is of some help. Bud

you should check the outline ctrl..for a mic...it could produce a noise...if you have your speakers connected to pc...check the position of the plugs and the volumen of mic put in down...

Did you check the record levels on the software you are using.
