Win7 x64 PR, no surround

[Flash.#13]

Hi guys, i installed win7 x64 and disappointed, there is no surround sound in PR. I have asus xonar audio card, with four speakers, and it works only like stereo. In XP it work normal, with surround, but i cant fix it in seven. Is there any solution for surround in PR? Or i need to change operating system?
