Im Having static sound from my speakers Acer aspire Es1 512 22js

Im having  an issue with my speakers they emit static sound . At first i thought it was the speakers themselves but ive tried some recomended fix and found out that the speakers work fine but then after some minutes the static sound is back. Ive recently formated the windows and for the first week 0 problem then again the same problem came back but it wasnt tht bad after sometimes it went away, but right now it went back to the static noises again. There is no official acer repair shop here and honestly i dnt want to give my laptop for repair , so is there anyway to fix this ? Or is there someway to remove the speaker so tht i use a Headset  ?  Thanks
