What do you look for in it?

Hi Toleda,

I wasn't ignoring the post, just trying to understand what you were looking for so I could learn how to check that particular problem in the future. I've always followed your guides but it is just a series of blind shots to me, and any education I get on the matter helps.

Here is the DSDT file as you requested:
View attachment System DSDT.dsl.zip

I don't load a DSDT file because every time I tried to make one I ended up with the system completely unstable. When I first found your solution through the SSDT, that was perfect, and had worked for me until recently. I would like to avoid loading a DSDT as much as I can.

A lot of these seem to be all over the place with the directions because of the various amounts of different options. I'm trying to get HDMI audio with a GTX 970 on a 7series board with HD4000. Is there anyway I can be pointed to the specific set of instructions? I have a DSDT.aml that allows HD4000 HDMI audio, but that one was compiled from my old Mountain Lion drive, but I think it was causing boot problems with my graphic card, so I think that I may have to start over.

EDIT: Tried one of the PDFs and figured it out. Thank you Toleda for the write ups. It's pretty much the same for yosemite as other versions of OSX

Simple.

1. Select the matching processor graphics/motherboard series
2. AMD/Nvidia HDMI audio is installed with every Desktop configuration

dsdt/ssdt HDMI audio

I am now officially lost as to what to do next. I still have had no luck getting the HDMI Audio to function. Chutoro seems to be the only Framebuffer I can get to function that video works on both my monitor on the DVI port and my TV on the HDMI port. (Mirrored)
I also have video sucess if I remove the DSDT edit for Device GFX0 but then I guess Clover Boot is using generic framebuffer ATY.
Either was still no HDMI audio. I know that HDMI audio did work in Mavricks with no Framebuffer edits added into the DSDT. Only the HDAU edit.

This time I have included a txt file showing rom dump layout from my AMD Diamond 7750 card.

I have Upgraded (Fresh Install) to Yosemite and cannot get AMD Diamond HD7750 "HDMI" Audio to be detected. Everything else including graphics working perfectly for primary monitor on DVI and secondary mirrored to Samsung TV via HDMI (but no sound).
In Mavericks I could ALT-Click sound Icon and select either onboard analog audio or HDMI audio

Specs:


OS X Yosemite 10.10 New Install, Gigabyte H61M-D2P-B3, F12 Bios, AMD Diamond HD7750 1GB, Clover Bootloader, DSDT.aml with edits done in actual DSDT.aml for all including onboard analog audio and AMD 7750 Graphics w/Chutoro framebuffer referenced in DSDT.
Only extra Kexts loaded by Clover are FakeSMC and Ethernet.
Only modified Kext is AppleHDA for analog audio.

All related files attached.

I am stuck as to know what to do next.

Sorry if I seem really dumb at this but I thought I was doing great with everything else working.
Any help would be great.

Thanks
Steve

dsdt/0 errors, damaged, not useable, delete
Applied clean compile 3 times and removed dsdt/discrete graphics; apply any patch one time only.
Start over with the native dsdt.

Exactly as you described. No erros in two logs (Clean compile 3 times and Compile a new patch of Audio_ID1 ....); Rebuild cache; After restart in DCPIManager Intel Codec appear and Realtek ALC892 (working) already in previous, but in sound (System Preferences) i don't get HDMI output.

I know that HDMI audio did work in Mavricks with no Framebuffer edits added into the DSDT. Only the HDAU edit.

The reason only Chutoro framebuffer works is because your dsdt is set to inject Chutoro.
1. To test the default framebuffer, remove Chutoro injection.
2. To test any other framebuffer, edit dsdt/Chutoro to the framebuffer you are testing. Test only the framebuffers that have an HDMI connector.

With the files attached previously, HDMI could not have worked in Mavericks. Attach a working HDMI audio Mavericks IOReg to prove me wrong.

Exactly as you described.

Total misunderstanding.
What you did wrong: Clean compile 3 times
Correct method: Apply any patch one time only.

Start over with the native dsdt, apply each patch once. Reply with edited dsdt.

WHOA!!! That did the trick, that simple!

Thank you!!!!!

I was looking at the PDFs again, to try to find where I messed up. Turns out that I couldn't find any info on when to check for p0p2 or not, thus why I kept the same SSDT I had chosen before which worked.

Here is where I think I messed up, and where you could probably put a note:
I remember reading audio_hdmi_8series/ssdt_8series/README.txt, and that pointed me out to audio_hdmi_guides/[Guide]_OS_X_hdmi_audio-ssdt_v2.pdf.zip, and in there I found the "ssdt Download" in which you say "Select appropriate ssdt", and there is where I should have switched to the no p0p2, but I didn't, and kept the wrong one. Perhaps you could add a hint there on how to select the appropriate ssdt.

When I saw the different SSDT, I rolled back some changes in my clover (removed the SaSsdt drop and returned the DropOEM I used before) and gave it a try. Worked on the first attempt!
Thanks again!!!! The rock'n roll is filling the room now!

P.S.: By the way, I don't know if you still want this for any reason, but here it is:
