[libvirt] Put the audio work on Windows 2008 Server 64bits

Hello, I am trying to put the audio audio work on Windows 2008 Server with 64bits but without success. I have tested with sound model ac97 and hda, and i always get the same error: the devices appears on Windows Device Manager with following message - "Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)". I have qemu-kvm 1.2 and libvirt 0.10.2. I also tried different drivers with different sound model combinations but no success. Any suggestion of drivers that can i use and how can i get audio device working?
