The ambient sound throughout level 4 is faulty. It's the snowy level where you start on a mountain. I can hear strong winds, but there's a lot of audio distortion. To be more specific, there's this constant crackling sound whenever this ambient wind sound is playing. My speakers are fine, plus, I've tried it with headphones and the problem is still there. Audio drivers are up-to-date and I haven't encountered any sound problems in other games. I'm using Windows 8.1 64-bit and the game runs otherwise perfectly

Anyone else encountered this, and if so, do you know of a fix? Cheers.
