Mountain Lion HDMI Audio

Sorry. DSDT and ioreg are attached.

Yesterday, you were closer to the solution than you are today. Undo what you did. From my previous reply: "The reason you have no audio is the native AppleHDA.kext is installed. Install the 889 version of ML: Optimized Realtek AppleHDA - Preview/Alpha with KextBeast."

Sorry, my text was a little ambiguous. What I meant is: I took the Optimized Realtek AppleHDA from the linked thread -- without the HDAEnabler included in the zip and without any other HDAEnablers -- At least that's what I thought. Your comment made me double-check S/L/E.

Turned out, that KextBeast also reinstalled the HDAEnabler889.kext I had stupidly backed up to the desktop. After removing it, the audio device was back again with HDMI recognized.

Thanks again for your help!!! And sorry for my stupidity in the last step. I hope this didn't cause much work for you.

cheers,

The new method has several improvements. Suggest starting with the native dsdt, apply the new patch file and install.

OK, here's something interesting. Played around with the DSDT edits last night. I left it off with HDMI audio not working. Then I did the 10.8.2 update tonight, rebooted and suddenly my Sony AMP shows up under Audio sources, video after sleep suddenly works and no errors. Again, it didn't work before the update.

I then removed the DSDT file and the HDMI audio is still there?!?

Hey everyone,

I've been busy these past few weeks since I built my loverly Hackintosh (stupid school), but now I am trying to get this irksome HDMI audio out working on my GA Z77X-UD5H and GT 640 combo. Also running the i7 3700K, but I really only care about audio out from my GT 640.

I've run into two problems, really. One - there is no DSDT available for the UD5H. However, I created one using the Chameleon app - it gave me a DSDT.aml, and a DSDT.dsl. See attached? Do I need to install these, or what?

Second - not sure if my system is a Gigabyte Award BIOS or the AMI BIOS deal... I know it is a UEFI so shouldn't it be the AMI one?

Thanks mates - cheers for speakin' like a pirate day.

See [GUIDE] Creating your own DSDT for most boards. Look at the DefinitionBlock; A M I.

The native AppleHDA (all ML) supports HDMI audio with a valid layout-id and HDMI audio dsdt edits; no surprise there. If you have a dsdt anywhere on your system, Chimera/Chameleon will find it and use it. Fortunately, it found the dsdt with the HDMI audio edits, again no surprise. I expect improvements in the video drivers in 10.8.2. Bear in mind, no Mac has been released on Mountain Lion with external displays.

I'm just now getting to do this updated fix, but I had a question. When editing (_ADR, 0x00010000) am I changing the ADR under GFX0 or is it one of the others? Right now it's (_ADR, Zero). (and as a side question, is ADR an abbreviation for address?)

Otherwise I'm only changing layout-id under Method (_DSM.. to 0x03, 0x00, 0x00, 0x00 for my integrated graphics correct? I'm using the integrated hd4000 graphics of my Intel ivybridge i7 with a Z77 Nortbridge MOBO. I'm pretty sure I understand the rest of the instructions.

I just did the 10.8.2 update, so would that effect my native dsdt, or is the native I extracted under 10.8.1 still legit?

GFX0 address, no change. _ADR is the PCI address. Yes on layout-id 3. dsdt changes with a BIOS update. It is rare for an OS update to force a change in dsdt. That said, dsdt/HDEF/layout-id has changed from 10.7.x to 10.8

Ok... I've done something wrong and I'm not sure what. I have no audio outputs. Here's my IOReg and edited DSDT.
