I had this issue as well. I installed the update and the ATI driver 13.11 at the same time. I thought this was an issue with the driver, not the game, and I performed a system resotre. Now I cannot open battlefield. I created a thread outlining this issue. What course of action should I take? i believe that performing the system restore after updating BF4 could have caused serious errors in the game, and I am afraid that I wil never play again.
EDIT: I am performing a repair. will check back in once complete
EDIT 2: Okay, good news. I performed a repair install, and everything works fine now. I can now launch the game, and my sound is perfectly fine.
I believe the issue may lie in the drivers used. I reverted to my old driver, 12.xx, and after the rapair, the update is intact and my sound is working fine. The driver linked in the update brief might have caused these problems.
