Help with Mountain Lion HDMI audio on Z77-UD5H and HD4000

[phillymavs32]

Is Chimera v1.11? If no, update Chimera. If you are using GE=Y, change it to GE=No. Are you using DSDT Editor or DSDTSE? What are you using for AppleHDA.kext? Confirm you have the 898 audio codec.

latest chimera. I was using DSDTSE. I didn't have an AppleHDA.kext on desktop. Not sure where to get it. I'll try to see if I can get back with GE=No. I may have to reinstall because I can't even get back into ML through safe mode

Edit: GE=No got me back on

Boot with -v to see what the last message is. Download DSDT Editor from the link in Post 4. Install MultiBeast/Patched AppleHDA/ALC 898. If you want on board audio working before you start the dsdt edits, install the Non-DSDT Enabler/ALC 898 (it will be removed later). With your agreement, I'd like to you test the Ivy Bridge HDMI Audio Edit kit.

Did you want me do do DSDT first or just select these options in Multibeast? Because I get no other sound devices in System Preferences after selecting those in Multibeast and restarting.

I am not clear what you are doing. Do you have a boot problem, a dsdt problem or an audio problem? The priority is to get a system that boots successfully. I assume you had that without a dsdt. Putting an unedited dsdt in the Extra folder should not change the ability to boot.

everything boots fine. My problem is that I have no audio period. I had that boot problem because I ran chimera 1.11 and it removed my string for HD4000 but that's fine now.

I'm just trying to get audio, mainly HDMI because I have my build hooked up to a HDTV. I'm just not sure where to start.


EDIT:

So I finally got sound.. Now I just need HDMI audio for my board.

Reply with the dsdt you are using and a copy of IOReg (with onboard audio working). If needed, [Guide] How to Make a Copy of IOReg.

i'm getting the program right now, but there was no DSDT in the process to get audio or for anything installed.

Lets get started. First step, clean compile of dsdt.
1. Download attachment
2. Copy Downloads/hdmi_audio_dsdt_editing_kit_beta to Desktop
3. Copy dsdt to Desktop/hdmi_audio_dsdt_editing_kit_beta folder
4. DSDT Editor/Open Desktop/hdmi_audio_dsdt_editing_kit_beta/dsdt
5. DSDT Editor/Compile dsdt
6. DSDT Editor/Fix Errors/Compile dsdt
7. DSDT Editor/Patch/Open Desktop/hdmi_audio_dsdt_editing_kit_beta/clean_compile/clean_compile.txt
8. DSDT Editor/Patch/Preview Before/After (optional)
9. DSDT Editor/Patch/Apply
10. DSDT Editor/Compile dsdt
11. TextEdit/Open Desktop/hdmi_audio_dsdt_editing_kit_beta/clean_compile/dsdt-_HID_error
12. DSDT Editor/manually add "Return (Zero)" to line 11055 as shown in dsdt-_HID_error
13. DSDT Editor/Compile dsdt
14. If you have errors, start over with native dsdt
14. If you have 0 errors, you have a clean compile of your dsdt
15. DSDT Editor/File/Save DSL as ... dsdt_clean_compile to Desktop/hdmi_audio_dsdt_editing_kit_beta

Attach a copy of dsdt_clean_compile.
