There is already many topics about that, such as
http://answers.ea.com/t5/Battlefield-4/Crashing-after-patch-02-13-2014/td-p/2332977/highlight/false/page/7 However I copy something about my investigation I have made today from Battlelog forums: I have made a little investigation wheter it is hardware problem or software problem or just devs did not test and this is result. So, I have installed vanilla Windows 7 x64, did some basic updating, installed latest motherboard drivers, graphic card drivers, audio drivers... Downloaded Origin, downloaded BF4 - downloaded patch (1,4 gb), downloaded China Rising (4,4 gb) and it was all. I was little scared to run the game as I though it will run. But - it has not. Still same "sound loop crash" - ten server, ten crashes within 1 minut after game started. It is definitely some bug in the gamecode and I am so sorry to say that, but it looks like it must be fixed by another patch... Anyway there is no evidence of any possible patch before 18. feb as they will release another DLC - so I have spent nearly 120 € and after nearly half of year after release I am not able to play the game because of faulty update. So guys, further information... Its gamecode bug, I am nearly 100 % sure because even if I have turned off integrated sound card - it crashed within 5 second - Op. Locker, Gullian Peaks, even traning... Further investigation showed that using external sound card (SoundBlaster X-Fi) doesnt improve anything and still crashes in sound loop. So I havent shown my specs: Phenom II x3 720 Gigabyte GA-MA790XT-UD4P 8 GB RAM DDR3 1600 (Kingston, CL9) Gigabyte GeForce GTX560 SOC (clock is little below Titanium) I know it is not high-end, but it has been runing at least. Not now.
