I have just found a fix for our integrated-sound-card problem !
Basically you've got to modify some sound files (ex. explosions) with a program which allows you to change them- lower their quality
I'll write a new thread (dedicated for anyone with integrated sound card problem in the future) in ~8hours (im sooooooo sleepy, it wasn't easy to find an appropriate program)
I've just finished testing and it works really fantastic- Bismarck mission on external camera with not even one freeze (100% details and all IQ options ON)



Also- all explosions without freezeng- yeaaaaaaah now I see they look really fantastic
And sound quality difference is hardly noticeable- after few minutes you forget that these are low-quality sounds.
