The other day I updated my bios to version 1304 off of the Asus website. I did a clean Mavericks 10.9.4 install. Using my DSDT and SSDT, and selecting Multibeast ALC 892 and Series 9 Motherboard checkbox only, the sound started right up next boot. (After I did the EFI method referenced in an earlier post).
Other than the FakeSMC and Intel ethernet driver, it's basic a vanilla build. The graphics card works OOB, and my wireless card also works natively also w/ Dropbox working etc. I use the Mac Pro Late 2013 smbios in the hopes I will be able to use 4k @ 60hz via DP1.2 when I get some cash.
My org.chameleon.Boot.plist is minimal:
HDAEnabler=Yes
HDEFLayoutID=01000000
Legacy Logo = Yes
Quiet Boot=Yes
SSDT=Yes
UseKernelCache=Yes
The SSDT=Yes is the only thing I put in the file, and placed my SSDT.aml next to my DSDT.aml file in /Extra. Any additional entries Multibeast put in my boot.plist file I removed.
I never put my system to sleep, but I did test it off the Apple icon menu selection. The computer when to sleep -- I came back five minutes after brewing some coffee and hit the space bar and it woke right up.
Sorry if I am a bit vague in my process, but made presumptions that the reader would understand a lot of what I said. Hope it helps someone. I have uploaded a copy of the patched DSDT that I used. An expert may be able to tweak it further, but I had no compile errors after I addressed the issues that MaciASL reported. The dsdt file:

The SSDT I used I made /w MaciASL also
made for the specific intel chip listed below. View attachment SSDT.aml.zip
I am in no way an expert in any of this. I stumble in the dark figure my way around w/ the genius help of people here, Tonymac crews' excellent work.
