To be clear: Multibeast 5.1.1 and newer edits dsdt/Audio ID 889 (Lion/layout-id 379) to Audio ID: 1. If MB does not see dsdt/layout-id 379, it does not do any edit. In your case, Audio ID 389 (Lion/layout-id 185) was not edited; it remained as Lion Audio ID: 389. For the ML audio to work, the ML Audio ID must be 1, 2 or 3. Result, no audio.

Audio IDs changed in ML. See Mountain Lion: Optimized AppleHDA for Realtek ALC8xx
ML HD3000 HDMI Audio ID:3
HD3000 HDMI Audio (GA-H67N-USB3-B3 and GA-H61N-USB3)
- Edit dsdt/HDEF/layout-id to 0x03, 0x00, 0x00, 0x00.
- MultiBeast 5.1.2 or newer - Select/Drivers & Bootloaders/Drivers/Audio/Realtek ALC8xx/With DSDT/ALC889"
I actually try to make things easy, in this case, only 2 steps are required for ML onboard and HDMI audio. Too much information got in the way.
It's so simple, even Stephen Hawking could do it!
After great loss of sleep and 1-1/2 days of making numerous mistakes, the sticks I was trying to use as tools went together on me and I was able to knock some bananas out of the tree (channeling Richard Feynman).
After numerous hours of trying to figure out why edits I made to the F9 DSDT using DSDT SE would revert back to before I made them every time I moved the edited file out of DSDT SE's preferred working directory, I discovered that if I renamed the DSDT.aml to something else before I moved it, the edits would stick, even though the edits remained in the original working directory... now that burns my ass! I got so pissed at one point I threw the post-it pad with my notes on it against a table and it split into several pieces and it took me half an hour (including cursing) to find the piece that had my notes on it! Where are Curley and Larry when I need them!
Then, after I moved my edited DSDT.aml by sneakernet to my CustoMac Mini 2011 platform and installed it, I had audio, although some of the preferences were a little funny but worked, and no HDMI. I re-read some of my notes and finally realized that I'd edited in the wrong layout (1) instead of layout 3, and went back to editing again! For good measure, I edited a version with layout 2 as well, in case I ever need it. BTW, if anyone else needs to edit this, the offending code you need to change is on line 4893 of the DSDT for GA-H67N-USB3-B3 F9 BIOS.
After testing almost everything works as I expected it would. HDMI works great through my AV receiver, I didn't check the SPDIF output, but the volume control 'greys out' and is disabled as it should be so that's a promising sign. The green connector output on the rear shows up as 'Internal Speakers- Built-In' and switches properly to 'Headphones' when a headphone connector is plugged into the front panel jack (audio level still a little on the 'puny' side from my perspective), the rear black connector is working when 'Line Out' is selected. As for the inputs, I didn't have anything handy to test the second input labeled 'Line In', but I suppose it goes to the blue 'in' connector on the rear. The only oddity for me is the 'Internal microphone- Built-in'- it works when an electret mic is plugged into the rear pink 'mic' connector, but when the electret mic is plugged into the front panel, the designation changes from 'Internal microphone' to 'Line in'... the mic still works and has approximately the same sensitivity as when plugged into the rear pink 'mic' connector. All things considered, this is fantastic because a year ago a lot of this stuff wasn't working, thanks toleda!
So hopefully someone can chime in on which of the various ethernet and USB3 drivers work the best on the H67N-USB3-B3... please help if you can...
This was a good project to get me back up to speed after being off the board for about the past nine months due to a heavier-than-normal work schedule. And, I got to reference 2 physicists and 2 stooges in the same post- how often does one get an opportunity like that?!?!?
