Question about Dell A215 Computer Speakers
I have a loud static noise coming out of my computer speakers. I know its not the speakers themselves. I plugged in head phones and the noise is still there. When I play music the static drowns out the music and the song sounds horrible in the background. What is this? Sound card?
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 on battery.
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.
