Audio and Video slur

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.

Hey guys it's still me. The problem's getting worse and worse. Tried reinstalling the driver for video card and things were fine for about 2 hours. Then the slur was back again. Then updated Windows 8 to Windows 8.1. Still no results.

Anything would be helpful, this thing's driving me nuts.

I should add that the Windows Updates are not a problem anymore ever since I installed 8.1 - they get updated automatically, without any errors.
