GUIDE: HDMI Audio

Works for me as well.

This is going to sound crazy but this works with OS X 10.10 DP1 for me when it will not work with 10.9.3. I am running 10.10 on my Mac Pro 1,1 using Chameleon.

Did you use this command to get Yosemite running? It might have helped
Code: 
sudo nvram boot-args="kext-dev-mode=1"
reboot

I've rebuilt kext caches manually then, using this command
Code: 
sudo kextcache -m /System/Library/Caches/com.apple.kext.caches/Startup/Extensions.mkext /System/Library/Extensions
reboot

Thats how I also got Trim Enabler to work.

Yes I am using that flag with a modified version of Chameleon for 10.10. Any idea if if it might make a difference for my 10.9.3 install? I cannot get HDMI audio to work at all but it works fine with 10.9.0-10.9.2.

Update:
It seems to work sometimes and then disappear later if I rebuild my kernel extension cache. I am using version 1.1 of the kext that was given to me for testing. I am no longer using the kernel-dev-mode flag as chameleon has been updated and doesn't need it anymore.

Hello..

Im pulling my hair out trying to get hdmi audio out of r9 270x with dsdt edits.
Will this work with hackintosh 3.1 Mac Pro ?
 
Went ahead and tested a bit more. cMP 4,1 > 5,1 & flashed 280X

Summary, to clarify:

HDMIAudio 1.0 and 10.9.4 / 13E16 = √
HDMIAudio 1.0 and 10.10 / DP1 = √ (requires kext-dev-mode=1 flag)
HDMIAudio v1.1 and 10.10 / DP1 = √ (does not require kext-dev-mode flag anymore)

System identifies v1.1 as nvaudio, and Console reports this:
Code: 
kext com.exvision.nvaudio  100009000 is in exception list, allowing to load

Screenshots in #126 above show v1.1 installed. It was given to me by andrejkw for testing.

In System Report > PCI, v1.1 is properly displayed as Audio Controller, not with the personality name (ATY,HamachiParent) anymore. This applies to 10.10 and 10.9.x.

Update:
HDMIAudio v1.1 and 10.10 / DP2 = √

It is not working for me with 10.10 DP2 and only worked with DP1 using the kext_dev_mode=1 kernel flag.

Here is my sudo kextutil output:
Code: 
sudo kextutil /System/Library/Extensions/HDMIAudio.kext
Diagnostics for /System/Library/Extensions/HDMIAudio.kext:
Code Signing Failure: not code signed
ERROR: invalid signature for com.exvision.hdmiaudio, will not load

In contrast here is the result of another 3rd party kext:
Code: 
sudo kextutil /System/Library/Extensions/CyborgRAT.kext
Diagnostics for /System/Library/Extensions/CyborgRAT.kext:
Code Signing Failure: code signature is invalid
kext com.madcatz.driver.CyborgRAT  162009000 is in exception list, allowing to load
kext com.madcatz.driver.CyborgRAT  162009000 is in exception list, allowing to load

Update:
I noticed that you are getting "com.exvision.nvaudio" in terminal but the HDMIAudio.kext is actually "com.exvision.hdmiaudio" which is not in the exceptions list. The kext used to be named nvaudio before AMD support was introduced. I can get the results you got with yours if I modify the HDMIAudio.kext info.plist file and change the package identifier to "com.exvision.nvaudio" but it still is not working on 10.9.3.

After modifying the info.plist file for the 1.1 version of HDMIAudio I get:
Code: 
Diagnostics for /System/Library/Extensions/HDMIAudio.kext:
Code Signing Failure: not code signed
kext com.exvision.nvaudio  100009000 is in exception list, allowing to load

But, it is still not working in 10.9.3.

Update #2:
Modifying the info.plist for the 1.0 version of the kext and then replacing the info.plist in the 1.1 version of the kext with the modified one from 1.0 DID make HDMIAudio work in 10.10 DP2 without kext_dev_mode=1. I used the info.plist from the 1.0 version because there is an invalid signature error with the 1.1 plist.

I knew this beforehand since andrejkw told me that. It's called workaround or if you prefer, beta. And this is why it's not released here yet.

See, the author is working on it, and I'm pretty confident that he told you that too. He is currently in the process of getting a Developer ID certificate which may take a while. Until then you were given, and can use this experimental version of HDMIAudio. It identifies itself as the original NVAudio extension, which should allow it to load. How about a bit patience until he comes up with a finalized 1.1 version.

The 1.1 version that I was given did not identify itself as nvaudio. The info.plist package identifiers said hdmiaudio. We very well could have two different versions of the 1.1 kext. I have patience and I am simply reporting what I have tried with the 1.0 and 1.1 packages. Neither were working in 10.9.3 or 10.10 for me but I at least got 10.10 working fine.

There currently seems to be an issue with Nvidia cards and 10.9.3 that the developer has not worked out yet. HDMI audio does work with 10.10 DP2 though and it may work with 10.9.4 which will be released soon.
 
Rep

andrejkw,
Can you repost the .dmg ? The download link in the 1st post of the thread isn't working for me.

Incidentally, my setup is a mid-2012 MBP connected (via mDP-to-HDMI adapter) to the HDMI input of a Harman Kardon receiver, connected in turn to a video-only Epson projector.

My problem is that as long as the projector is turned off, the MBP sees the HDMI audio interface and transmits sound to the receiver fine, including 5.1 audio. However as soon as the projector is turned on, the HDMI audio option disappears from Sound Prefs, Audio MIDI Setup, VLC etc., and the only sound output device is the MBPs built-in speakers... makes the whole 5.1 reciever setup useless.

This is obviously some kind of EDID issue, and I'm suspecting something non-standard in the receiver, but since replacing the MBP with a Dell laptop w/HDMI port works fine, Harman Kardon tech support doesn't think it's their problem. I've spent many hours poring over EDID dumps, and am still not sure what I'm seeing, so hope I can use the HDMIaudio kext to be as permissive as the Dell.
 
Whoops..

Never mind, missed that Hennesie2000 reposted the extension on the previous page of the thread (thanks!).

So I gave it a try, but unfortunately, it doesn't solve my problem... Looks like I'll be stuck with the laptop speakers for now, and may eventually get a streamer to hopefully circumvent the issue.

Just a hunch, is the receiver setup to "pass-thru" the audio and video to the projector?
