Hello, everybody. Sorry if this is the wrong category. I've got a relatively new HP Envy 4-1035TX Ultrabook Laptop and I've had this problem lately: while playing a YouTube video or a song from my iTunes library, it keeps slurring and crackling. The problem is very sporadic: sometimes it will not slur at all, but other times it will once every 10 seconds. Playing a video in BS Player works perfectly fine, though. Thanks in advance.
