Typo Post #1, fixed; 10.8 or newer.
Not sure how you missed:
Post #1, Installation - MultiBeast_5.1.1 or newer
Download/Software,MultiBeast Archive, use the MultiBeast for 10.8.

Hi! I just built a system with Mountain Lion 10.8 and ALC887 is not working, I can see both soundcards on DPCI Manager correctly listed (ALC887 and HDMI audio) but I have no output devices on sound settings.

Any sugestions will be very much apreciated because I followed all the steps of this thread with no luck...

Thanks in advance!

Nevermind, it's solved.

I just used AppleHDA.kext and HDAEnabler.kext from another install with ALC887 and it's working.

Thanks anyway!
