Rampage IV extreme No sound on yosemite

[Rompicollo]

Hi all,

I've just installed Yosemite and after post-installation with Multibeast 7.5, I have no sound after reboot and I already tested old Multibeast versions, rebuild cache..etc
In chimera plist, I use : ncpi=0x2000 dart=0 -f
If I don't boot with -f, I get stuck at this line on the boot.

"pci168c,30 cannot assert wake from D3cold"
"USBF: 1.388 AppleUSBEHCI:: unable to get filterInterruptEventSource"
"USBF: 1.388 AppleUSBEHCI::UINInitialize - Error occurred (0xe00002be)"

Realtek ALC898
DSDT free
Audio ID 1


thank you for your help.
