GTX970 HDMI audio

[pinklerose]

Is it possible to have HDMI audio now?

I am using Chameleon and Yosemite 10.10.2.
In DPCIManager I can see nVidia in audio section

I have tried DSDT and SSDT option but no luck, system prefs not showing HDMI device.

Yes, it is. Make sure OS X is fully updated, then update your Nvidia web drivers to the latest version (346.01.01f01).

For some reason still not working. I have also tried with file in version 1.1.

I'm thinking to reinstall system and try from scratch, but I'd prefer to avoid that.

I used to have Radeon with working HDMI audio before on same installation and have a feeling that I didn't replace all files I modified before upgrading to nvidia. Unfortunatly I don't remember what changes I did.


Maybe that part of log gonna be helpful (all about audio):

That's really strange - it's working great on my 970. All I can say is to make sure you don't have any modified audio kexts (no VoodooHDA stuff, none of toleda's modifications, default AppleHDA). If you're working from a fresh system (in terms of audio) this should be working.

What you could also do is try VoodooHDA if you haven't.

OK, so I've installed voodoo and now I have HDMI sound, but it's working in stereo only. In midi configurator I can't hear any sound on any other speakers than left and right.
Playing any sound file in VLC makes system freeze.

All that means for me it should work without voodoo but something is wrong with kexts probably.
Any ideas?

Yes, that does sound like your kexts are broken. VoodooHDA works independently of AppleHDA, so if there is something wrong with AppleHDA it would explain why VoodooHDA works and andre's kext does not. Restore your AppleHDA kext to default, either by finding it online and installing it or by applying a combo update.

@toleda:

Many of us have used and appreciate your HDMI solution, but, unless I'm mistaken, this forum is not dedicated to it. Andre's solution works well, and if it can help someone enable HDMI audio on their Hackintosh it shouldn't be censored.

If running Yosemite 10.10.2 with Clover:

-Ensure OS X is fully updated
-Install latest NVidia web-drivers from here: http://www.nvidia.com/download/driverResults.aspx/83647/en-us
-Use Andre's kext and guide from this thread: http://forums.macrumors.com/showthread.php?t=1499797. Alternatively, place the kext in your EFI partition.

Follow these three steps and you should have HDMI audio appear as an audio output in Settings.
