I own a new 7586 2 in 1 Inspiron. Randomly, the speakers will begin to crackle and won't stop. This happens when I receive notifications from FB. Just tonight, I also couldn't listen to Pandora without the crackle in the background. I tried using great earbuds I own that never gave me a problem on my Acer (oohh!)...but I could still hear the crackle on them. Please advise. Thanks.
