I have a Lenovo y50 laptop and I decided to buy a pair of brand-new Ath-m50x headphones. When I try plugging the ath-m50x's into my computer there is a non-stop crackling, buzzing sound that no matter what I do it won't go away. However, when I plug in my cheap Sony headphones there is no crackling. I've tried deleting my Realtek drivers and plenty of research, but no matter what I do, nothing works. The buzzing is driving me crazy and it just won't stop! Please help!
