GUIDE: HDMI Audio

s.m.t. said:
Yeah, sorry should have stated that... 10.10.3 Nvidia driver 346.01.2f04

Edit: should also add running a 4,1 that has been flashed with 5,1 firmware...

You might have to wait for the next driver update. There hasn't been one since before the 980ti was released.
 
figured it the card might be too new... about this mac doesn't even show the 980Ti by name, just as Nvidia Graphics device...
 
Just thought I'd chime in. Updated to 10.10.4 and still no HDMI audio on my 4,1->5,1 with generic GTX 980. Web drivers installed, and verified the HDMIAudio kext is loaded. I get DP output to my 27" ACD but no HDMI out to the receiver. Works fine in bootcamp of course! Anyone know why hackintoshs are seeing success on Maxwell but not cMP towers?

Not sure why this is the case. For the longest time in Mavericks my GTX 570 would not get HDMI audio out on my Mac Pro 1,1 using the boot.efi method but if I booted Mavericks using Chameleon or Clover HDMI audio worked fine without changing anything other than the boot method.

With the Hackintosh I have HDMI/DP/DVI audio out of the GTX 970.

Just to make sure, are you running Yosemite?

I am using a GTX 970 with 10.10.3 and I am not having any issues with audio out through HDMI, DP or DVI.

HDMI Audio is working in 10.10.4 using the beta Nvidia Web Drivers and a GTX 970.

Well I'm jealous of both of you. I'm using a GTX 970 as well and for the life of me can't get HDMI audio to work. I've tried HDMI audio kexts, different Nvidia Web Drivers. Maybe I'm not using the right beta driver? What version is your driver Hennesie2000?

I am using the release driver 346.01.03f01. I am using a hackintosh though.

GUIDE: HDMI Audio




What you are getting in terminal is normal and it should be working. What GPU do you have?
Click to expand...


I get the same in the Terminal but no HDMI Audio? Under 'Audio' in the System Profiler I have HDMI/DisplayPort and under PCI I have my graphics card and a weird PCI id for Audio?

Any ideas Hennesie2000, I notice you said the Terminal report was normal?

See pics:

The PCI id for audio is normal as well. On a hackintosh using clover and a dsdt you can change that name to match the GPU name. I'm on vacation at the moment so I'll take a deeper look at it later.
 
Has any one figured out how to make it work in El Capitan beta? I couldn't get sound output through my 780 in Mac Pro 2008 using HDMI.
 
Is there any way to get this working in the latest beta of El Capitan? From what I understand the option to remove SIP is no longer there.
 
Guys, I'm having trouble enabling HMDI Audio on my GT 640. Here is my system:
Mac Pro 4,1 flashed to 5,1
OS X 10.10.4 (14E46)
GT 640 4GB (NVIDIA Web Driver 346.02.02f03 & CUDA 7.0.61) 10.5.2

I installed HDMIAudio 1.1.

I do not see any HDMI input in my System Report.

Any suggestions?

Thanks,

Have you tried using the stock OS X drivers?
 
Can anyone confirm if they've got audio through HDMI working on OS X 10.10.5? My 2012 5.1 Mac Pro has been outputting audio on 10.9.5 just fine. So I took the plunge, reformatted and loaded 10.10.5 (no audio). Reformatted again and installed 10.10.2, still no audio. Card is the AMD radeon sapphire 7950 MP edition.

Reinstall HDMIAudio once or twice and see if it helps. I found that sometimes it takes a couple tries before it will actually take hold.

thanks for the speedy reply Zorn.

Based on your suggestion, should I be installing then uninstalling the hdmi audio (as per original post instructions).

Or should I just be installing (clobbering) one install on top of the other until I get the result I'm after?

Likewise, do you suggest I use version 1.0 or 1.1?

Also, should I be punching in the following command before or after each install;

sudo nvram boot-args="kext-dev-mode=1

such a shame this hasn't been fixed by Apple with the 10.10.5 update...

When you run the ./install.sh in terminal, it automatically removes any prior HDMIAudio kext before installing again. I believe either one will work, but I like to go with the most up to date so I've always used 1.1.

You should only need to append the kext-dev-mode boot arg once, and it will be saved unless you reset your PRAM. No need to do this before/after each install of HDMIAudio.

Also, don't expect Apple to ever fix this - they are purposely blocking audio over HDMI or DisplayPort on tower Mac Pros. It's officially unsupported on these machines and you'll hopefully consider a "new and improved" Mac Pro - its' excellent 2011 laptop-caliber GPUs are deemed worthy to allow audio over HDMI/DP.
