[toleda]

you can run a gigabyte geforce 210?

GT 210 HDMI audio does work in OS X.

I do not know if I was wrong to follow the guide but I opened MaciASL and I added the sources github, after I selected first in the patch "UEFI clean compile" and I compiled and after "Desktop-HD4K/HD3K/AMD/Nvidia-A" selecting only because UEFI clean compile gave 2 errors, but when I reboot the boot was very slow and the mouse appeared after several minutes, in verbose mode appears a new string "sound assertion", I attach the 2 files ioreg and unmodified dsdt.

The unmodified dsdt is not useful. Attached the edited dsdt and an IOReg with the dsdt installed. Clean Complies results in 0 errors and 2 warnings. IOReg shows audio is disabled; are you booting with a USB installer?

I have attached the file without modification to see to see the original and ship them to know if the two patches are good for me, mountain lion is installed on my HD with Enoch 2244, I installed Enoch and the only bootloader because I recognize the hd display.
The guide has been carried out correctly?

Nothing attached. Audio is disabled in your system; fix that first.

I installed VodooHDA for audio ALC662 that works well and now I find 4 HDMI audio outputs and a single but still works with the audio icon is not adjustable, I extracted the dsdt with windows and filled with 2 patches applied.

You do not need any dsdt edits for Voodoo. I have never used Voodoo. This thread is for AppleHDA HDMI audio. Your post is off topic.

My answer is not off-topic because you asked me to turn on the sound, which is the internal ALC662 and I downloaded the kext, I thought it was first necessary to enable this and then the audio hdmi, maybe I misunderstood me, pci video card instead as I have a gigabyte geforce 210, what should I do to do to make good the audio hdmi? I'm interested in this.

I asked you to enable audio. You did without using AppleHDA.kext. Voodoo/Voodoo HDMI audio is off topic.

Thank you, Toleda! I appreciate the work you do. I followed your guide and now have HDMI audio working on my latest machine.

Asus P8Z77-M > Gigabyte 6850 (Lotus FB) > Asus VE278 monitor > Line out from monitor to 2.1 speaker system.

I would have normally been satisfied without HDMI audio, but the popping from the ALC887 onboard sound prompted me to find another solution.

Thank you for the guide and for your MacIASL patch source!
