This is one thing I cant figure out for the life of me and I was wondering if anyone else has had the same problem and fixed it...

Whenever a map is loading in DC,BF, and Vietnam I can only hear people speak. I cant talk till after the map has loaded on my machine.. Drives me nutz.. My sound drivers are up to date. I dont have a sound card couse my ASUS P4C800-E Deluxe has

-ADI AD1985 SoundMAX 6-channel CODEC
-Audio Sensing and Enumeration Technology
-support S/PDIF out interface

and theres no bios updates that I have found for it.

Any help would be greatfull
