I read some of the other recent posts around AppleHDA version, and tried replacing it, which seemed to make all audio disappear, then I realized I had a permissions issue, which I fixed. Then I realized I needed to have my layout-id set to 3 instead of 1, and when I did that, it fixed...

I thought the correct ML layout ID was 1, as I have 6 port on my onboard audio -- is that what you're asking? Confused again.... f

Hi Toleda, I'm back again, having given up trying to get HDMI audio working the GT 210, and instead trying with the integrated HD4000 chipset. So the good news is I got HDMI audio working (yay!). I installed the 10.8.2 update, then ran your DSDT patch file, and the HDMI output finally...

I'm actually building this system for my brother, to be used as a desktop PC / media center. HDMI audio is important to him because of the way his TV / stereo is set up. This is built on a GA-Q77M-D2H motherboard which has HD4000 graphics, but I was experiencing some weirdness with the onboard...

Thanks again for the help -- I'll keep trying. Maybe I should ask another question while I'm at it, in case I run into a dead end with this card -- is there a particular video card that you would recommend on which HDMI audio is known to work, and would be less of a wildcard than the GT 210? f.

I'm trying to figure out where to find the device_id's for the 210. Can you point me in the right direction? I found a few other people mentioning getting this card working, but I didn't see the values used explicitly posted. f.

So I'm reading the nvidia_gt4xx_5xx_case_studies.pdf document, and I've come to the line where it says: a. NVDANV50Hal.kext/Contents/Info.plist 10de 0ca3 present, no editing required, GraphicsEnabler=Yes This is under the GT 240 section, and I have a GT 210, but it's the closest match I...

Ok, so I followed the steps you outlined in your last post, and got back to a point where analog audio devices show up as output options, but still no HDMI (as opposed to no devices at all). Part of that was editing the DSDT layout-id to 0x77, 0x03, 0x00, 0x00, and I verified that it now matches...

Wow, I'm really confused. So as far as the audio kext's go, after my initial OSX install, I ran Multibeast and selected 'Audio- Realtek ALC8XX - Without DSDT - ALC887' but I think I may have accidentally selected both legacy and current at the same time (not sure if that's why you saw...

I searched and found 1x for HDEF, PEGP, GFX0, HDAU, and IGPU. I compiled the DSDT, put it in the Extra directory, and restarted, but still didn't see HDMI as a sound output option. I've attached a .zip with the edited IOReg and DSDT files. Thanks, F.

Ok, that makes sense. Not sure why I thought editing the patch file would be necessary. So previously I did apply the patch, compile, save dsdt.aml in the Extra folder, and when I rebooted I didn't see the HDMI output as an option in the sound preferences. Would it be useful to see the...

I'm a little lost here. I see PEG0@1 -> IOPCI2PCI2PCIBridge -> PEGP@0 (see attached screenshot) I'm not sure what I need to edit in the patch, file, if anything. Just for the hell of it I tried running the patch file without edits, but HDMI didn't appear in sound preferences, so I figured...

Ok, I patched with the clean compile as you said and got it to compile...one step closer! Now I'm at the section with the text: "Edit Open ML_...Series...hdmi_audio_.txt- TextEdit" I have onboard sound with 6 1/8" jacks, so I'm assuming that falls under 5/6 port on board, and I wouldn't...

Hi Toleda, Thanks for the quick response. I did hit the fix errors button -- below is the errors that were remaining, along with the corresponding code: 10484 Error _HID suffix must be all hex digits (GH) Name (_HID, "ABCDEFGH") 9937 Warning Reserved method must return a value...

Thanks for pointing me in the right direction toleda -- because it looks like my motherboard isn't on the supported list for the DSDT tool, is it safe to assume I should go the EasyBeast route to generate a DSDT (I get a ton of compile errors in the tool)? I'm guessing that if it messes anything...

Hi, I'm pretty new to this, but i wanted to chime in. I just built (or am in the process of building, rather) a system with a GA-Q77M-D2H motherboard. Most everything worked well without much effort, but audio over HDMI does not work, and for me that's not a small problem. I've been trying to...

Hi, I've been reading this post for the past couple of hours trying to figure out what it means, and while I keep getting a little further, I'm still really confused. I have a Q77M-D2H and there's no DSDT available (that I could find at least). I tried extracting my own DSDT and compiling it...

*Success! Fully functioning OS X 10.8.1 ML / Windows 7 Build Thanks for the tips! -- I have the same motherboard and followed your multibeast steps and I'm sure it saved me some time, but I've still got issues. I can't seem to get the system to reboot / shutdown -- it goes through the motions...

Hi, I'm pretty new to the mac world, and I've read this entire thread, and lots of other posts, attempting to digest everything, but I'm still in trouble here. I attempted to do an update to 10.7.4, and now I'm getting a kernel panic, with the final line I see referring to USBMSC Identifier...

The same thing is happening to me with a clean install of Lion, no previous OS. It's definitely the right password, as it tells me if I enter it incorrectly. I'm installing to a system that matches the mac pro config on this site, with an Intel SSD drive. Thanks, f
