I posted this issue to the several forums so I was lazy and didn't post the solution, which helped in my case, to the every forum. Sorry

Just thought that if someone has the same problem, he can ask it here.
But to the business. Here's the tip I got in one forum:
Go to the device manager and under the computer section there's ACPI Uniprosessor PC. Choose that with right button and take update driver. Don't let the computer search the driver, do it yourself (lower one). And again the lower one to list the drivers. Take Advanced Configuration and Power Interface (ACPI) PC, it's in the compatible list. It need couple reboots and done.
At least that helped for me, sound doesn't cut out anymore, at all.
