Good afternoon.

Recently, about two weeks ago, I've 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 smoother than 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 https://www.youtube.com/watch?v=LBJo2KvFOCQ ). 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 sound whatsoever. Same went when I had a go with my iPod : no static sound, the audio was smooth and clear. 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 had read on some other 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.

It really bothers me because I cannot fully enjoy any song whatsoever. Is there anything I can do to fix this problem without having to send it to a repair center? It usually takes ridiculously long to have even small problems as such fixed.

Thank you for the help and for your time.

EDIT:
Okay guys so I sent my computer in for repair and I just got it back. They replaced my mother board, however the problem is still there. I don't know what to do anymore. Should I call them and send it back again? Maybe they missed something during the check up, maybe it's the headphones jack that is at fault.

If it was intermittent static, I would check for a loose connection. As that doesn't seem to be the case, and you've removed external components, I would suspect interference from another internal component due to insufficient or compromised shielding. A compromise you may be able to find if you want to disassemble your laptop. Insufficient shielding would require test equipment that most people don't have. If it's a quality issue, you should be able to find references to it online, in which case you may want to consider getting a refund and look at a different laptop. If it's a quality control issue, you'll need to send it in.

Sorry - probably not what you wanted to hear.
