About two weeks ago I bought a brand new ACER Aspire E1-570G and I've had no major problems with it (aside from a few freezes the first days but now it's smooth as butter). My only problem is that yesterday I've noticed a static sound that can be heard over the music when I have my headphones on (it crackles in rhythm with the music). It's pretty loud, to the point it actually distracts me from the actual music. I listen to a lot of EDM, Trance in particular and the static noise can be heard during the parts of the song wherein the lower frequencies are more intense ( For example: I hear it on this song, from 2:48 onwards
). At first I thought it could be a problem of the headphones ( I own a BOSE AE2) but then I ran several "tests": I used the headphones on my mom's laptop, a Lenovo, and I listened to the same songs; no static noise. Same went when I had a go with my iPod: no static sound, the audio was smooth. Just to make sure for good it was my notebook at fault, I changed headphones and this time I used a pair of Sennheisers; the static could be heard crystal clear.
I took the advice I read on some forums; I unplugged my charger, my cooling pad, my mouse, basically everything except my headphones and I even cleaned my jack; still nothing, the static sound could be heard loud and clear.
Is there anything I can do to fix this problem without having to send it to a repair center?
