GUIDE: HDMI Audio

[keantan]

Hmm, so I wonder what is different since you are able to get HDMI audio with a Maxwell card and that driver when others can't, myself included. I am running the newer driver though because I am on 10.10.2 but I couldn't get it working with 10.10.1 either. I am running DVI to HDMI, maybe I should try straight HDMI but that causes issues with the Clover boot screen and my monitor (black bars all the way around).

OK Here are the steps I used:

After installing 10.10.2 and the driver 343.02.02f01 (not f02), I then installed the latest CUDA driver and the the HDMIAudio 1.1 kext. I then enabled the bootflag as per markpaterson's post and restarted. The screen stayed black but I could log in to my mac via screen sharing, and noticed that the driver in use was the default OSX driver as per the NVIDIA control panel, changed this back to the NVIDIA driver and I was back up and running. THEN I enabled audio through the audio output settings.

As far as I can remember, DVI does not support audio at all, that could be why yours is not working - correct me if I am wrong here. Not sure why your pure HDMI cable is not working. I am currently using full-size displayport to full-size displayport. Conveniently, since my graphics card now supports displayport 1.2 I can now set my monitor to use DP1.2. I have yet to try out any DP1.2 specific features yet like display daisychaining since I don't have the right hardware.

I don't know if this helps. Hopefully it does.

DVI does support audio when using a DVI-HDMI connector and it was working this way with 10.10 and its respective driver. Upon updating to 10.10.1 and its driver HDMI audio stopped working as it no longer shows up in System Preferences. Many others in this thread have reported no HDMI audio after updating to 10.10.1 with Maxwell based cards. Things are a little different for me since my 970 is in a Mackintosh versus yours being in a Mac Pro.

So interestingly I tried an HDMI cable and the black bar issue is gone during the Clover boot menu but alas still no audio.

Hi everyone, and thanks andrejkw for making this extension!

I'm having a little weird trouble I haven't seen mentioned on this thread. After installing HDMI Audio 1.1 and enabling developer kext, I don't see HDMI audio under Preferences > Sound... but I do see "HDMI / DisplayPort Output" under System Information > Audio > Intel High Definition Audio.

Any ideas as to whether this is good sign or bad, and what I could do?

System details:

Mac Pro 4,1 > 5,1 of course
OS 10.10.2
GT 120
GTX 480
NVidia web driver 343.02.02f02

Some more notes:

. HDMI Audio 1.0 extension has no effect—including no mention of HDMI/DP audio out under System Info.
. Connecting HDMI display to the GT120 or GTX480's DVI ports with an adaptor has no effect.

Thanks for reading!

HDMI Audio is broken starting from that version of the web driver.

If possible, try downgrading to f01.

Hey,

Thanks for the quick response! I managed to find the f01 version of that driver online, but the same symptoms persist...

 

[Tony6411]

Ok so i got it working with latest NVidia drivers and OS X 10.10.2

My setup is…
EVGA GTX 680 Mac Version
NVIDIA Web Driver 343.02.02f01 (up to date as of Feb 1)
CUDA 6.5.46 (probably not essential for the HDMI audio)
OS X Yosemite 10.10.2
HMDI Audio 1.1

Here's the steps I took… (Obviously starting with 10.10.2, CUDA and Webdriver 343.02.02f01)

I installed HDMI Audio 1.1, then before I restarted I adjusted my bootarg code to allow unsigned developer kexts…

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

Rebooted, and HMDI and DisplayPort appeared as audio devices.

To undo unsigned kext mode, type terminal command is…

sudo nvram boot-args=""

But this will probably disable the driver again.


I assume the driver just needs updating to run as signed in Yosemite 10.10.2.

For anyone having issue follow this exactly and you will have hdmi audio i have this working on 10.10.2 flawlessly and can confirm it works.

 

[vampirexx]

What is your gpu? Doesn't work on maxwell chip only on fermi and kepler.
So GTX 7XX up to 9XX should have almost all hdmi audio broken, if you have 6XX gpu I guess it s not a maxwell

Yea no luck with a Maxwell card. BTW, the only 700 series Maxwell card is the 750ti.

 

[vampirexx]

Hen I have an NVIDIA GeForce GTX 750 1mb vram, it's asus branded but to have it recognized by osx, I had to flashed on it the palit bios so now it is 0x1381 0X10DE 0x00a2

No luck with a 660Ti either on 10.10.2 (14C109). Neither with 343.02.02f01 nor 343.02.02f02. In fact on 343.02.02f02 the HDMIAudio 1.1, or something, seems to wreak real havoc as NVIDIA driver seems to crash and shows all bonkers values for the card and even iMessage fails to start due to some internal error.

Without HDMIAudio the driver (f02) works ok but obviously without sound.

I don't have any issues having the kext installed and using the latest drivers, just no audio.

 

[Vmaatta]

Yeah, might be unrelated. I did have 1.1 with f01 long on this before starting to fiddle with it yesterday and then ran into the issues. Interestingly, issues started only after:

kextcache -system-prelinked-kernel

kextcache -system-caches

Again, probably unrelated. But after re-installing f02 and removing HDMIAudio everything is fine.

 

[Pawprints]

After f02 (latest drivers) I've gone back to OS X and living with it.

I tried F02 (latest drivers) but this broke my mac pro completely so much so that I had to revert to a time machine backup before all the problems. Although not perfect I'm making do with the OS X drivers where the HDMI audio 1.1 works. Not quite as good performance wise to Nvidia's but I will live with that I think as it's not unbearable.

I will be brave when we get F03 in the hope they're more stable on my machine

 

[jelockwood]

I have read (most of) this thread and a few others in order to try and get an understanding of what the current situation is regarding Mac video cards.

It seems that on the one hand the 'best' card currently to get audio out from is the GTX 680 - correct me if I am wrong, and this this uses the HDMIAudio1.1 patch with perhaps a brief bout of enabling/disabling developer kext mode, but that on the other hand the GTX 680 is insufficient for proper 4K 60Hz support via both Displayport MST and HDMI 2.0 ports.

Assuming the HDMIAudio patch gets fixed again for other video cards, what video cards would be best for 4K at 60Hz via Displayport and HDMI 2.0? Ideally with both SST and MST support for Displayport.

Would using an active Mini Displayport to HDMI 2.0 adapter which supports 4K give 60Hz? I get the impression these are also limited to 30Hz so would not be a workaround for lack of HDMI 2.0 on the video card.

Many thanks to everyone trying to get round Apple's artificial crippling of video cards.

Apple is not intentionally crippling them. Nvidia web drivers broke support if you read and follow other sources.

Your entry-level card for 4k@60Hz via HDMI should be GTX 960.

Gigabyte ud3lr p45 Working Hdmi

So after days pulling hair out on this, I've finally got hdmi audio to work on my Nvidia Gtx 610 2gig card with dvi, hdmi out I'm using the the Mavericks Vooda HDA 2.8.6 and WebDriver-343.02.02f01.pkgdriver installed to system/extentions once i deleted my clover boot efi folder and re-installed so had a clean Config.plist , all was fine for what ever reason you need to use either mac pro 3.1 5.1 or 10.1 as u smbios file or it simply will not work! at least for me I've included my clover config.plist for viewing to match or try for Gigabyte-ud3lr p45 socket 775 intel older motherboards maybe newer to? not sure


ps forgot to mention I'm using Yosemite 10.2.2 latest OS X and Hdmi is working great
also not under System Preferences/ sound i have Hdmi 1 & 2 output! number 2 out is the working one

I have seen else where this should work without a separate graphics card but I can't get it to work. I have done a fresh install of Yosemite with clover. Any help would be great. I know my board works as it still works on Mavericks

Hi, I tried this kext with clover, but no luck. Any ideas?

My specs:

Core i5 3570T, AMD HD7770, Zotac H77-ITX-A-E

My video bios and decoded message are attached.

 

[sonar12]

nvda_drv=1

try this you may have to register but its free to do so
http://www.insanelymac.com/forum/files/file/380-high-definition-audio-codec-installer-hackintosh/

Also note by having this enabled in Clover Configurator nvda_drv=1

You will have no Hdmi Audio, once i disabled it and rebooted, my Audio was working again, the whole time installing and un-installing kext! This was the Culprit

DISABLE nvda_drv=1 if your using a Nvidia Card, You do not need for web drivers either thats BS, your nvidia card just has to be compatible

That flag itself is not the culprit. The problem is that any card that requires the Nvidia Web drive will not work with this HDMIAudio.kext. What that boot flag does is enable the Nvidia Web driver. Any Maxwell based card has to have that flag in order to function. Cards that don't need that flag will use the default OS X Graphics Driver and then HDMI audio will work.

Yes thats absoulelty correct, Well it fixed my problem anyway and even with the flag enabled and the audio kext not installed my web driver kept changing back to the OS X default and would never load the web driver once i had it working i had no dual monitor support, so wasn't to thrilled about web driver anyways Thanks

If you are talking about the Nvidia preference pane still saying that it was using the "os x default driver" while using the nvda_drv=1 boot flag, it is purely cosmetic and you were in fact using the web driver. If your card is supported by the default driver you are better off using that anyways.
