It was working during beta but now for some reason I have no sound. I'm using a Soundblaster X-Fi Titanium Fatality. When I log in, the audio settings show it going through SPDIF and when I try to change it, the game crashes. During beta I had to plug in my headphones and could get the sound on but now with head start, I just crash when I try to switch.
I have the same problem. Sound worked fine in beta, but now it doesn't work. Plus if I try and change any settings the game crashes. I also uninstalled and am just patching the game to see if it fixes the issue.
