Sounds during loading screen

During the game's zone loading screens, I hear sounds of crashes, explosions, and fire crackling. This happens almost every time. The sounds usually appear after the files have decompressed, and the loading bar is at 100% (and I think that the sounds are delaying the levels from loading more quickly)
It must have to do with my sound card, but the GW support doesnt really help.

Sorry if this already exists, but i cant find it since search isnt working.

I've just started having this problem aswell so i dont think its your sound card.
(i hope not anyway) Have you tryed e-mailing at plaync? i might do if the problem persists.
