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.
