Today, 03:02 AM

but no HDMI audio.

Several issues:

HDMI audio - broken with latest Nvidia web drivers (343.02.01f01)

No reason to use web derivers with a GT 640

Fix: use native 10.10.1/Nvidia derivers


892 onboard audio- -applied audio_realtekALC-100.command and then applied audio_cloverALC-100.command

Audio will fail on next Software Update

Fix: install native AppleHDA.kext and apply only  audio_cloverALC-100.command


HD4000 - BIOS/disabled 

I click on Built-in digital output and bam, green rear start working as should. 

Simple answer, adding Built-in Digital Output to Aggregate Device should not work. No idea why it does.  

No way to verify as green works on all my test systems.

But there are other motherboard on which ALC892 when wake up does not lose sound?

My 892/Z97N and 892/P8H67-I wake with audio every time.  Other H97N owners have reported wake with audio working on Yosemite.

It is not all 892 or all H97Ns. In your case, it seems it is both of your systems.  Try Codec-Commander, Post #333, Yosemite: Audio - Realtek ALC AppleHDA

I have Audio in systemprefs and so on. But there is no audio from rear at any oiutput.

No need to post the guide.

IOReg does not show any audio playing or any audio device selected.  Suggest iTunes and green rear speakers.  Reply with new IOReg and attach debug.log.

Yes. But I don't understand why does not work my rear output and front work?

I do not understand why you say rear output does not work.  Post 481, says and audibly proves rear output is working.  The distortion is the result of over powering the speakers.

Is there anyone who tried or successfully enabled HDMI audio output on GTX 9xx cards?

Nvidia HDMI audio is broken with 343.02.01f01, use 343.01.02f01 or older.

No kext edits are required for Maxwell HDMI audio.

Correct dsdt edits are required, attach edited dsdt.
