Well, even after the latest patch I still have absolutely no sound, the opening cut scene is still suffering from horrendous stutter and my last discussion about it is long gone through inactivity. I've tried the oanlinst fix and that didn't work.
Edit: Open AL didn't solve the problem, I did all the basic stuff, verifying integrity of cache, reinstalling ect, a patch came out and fixed it though. I'm really not sure what the issue was. I'm sorry for anyone still having the problem, but I simply don't know the answer.
