What is very-very interesting, I found unreal solution googled on Internet willage. If I reboot and turn off Audio (called Azalia Codec in my version) in BIOS Setup and ther again restart with it enabled - all work fine now!

Thats all, all work. I think it sounds fantaskic, but seams helps not only for me...
