Haswell NUC HDMI audio

[minihack]

First, thank you to SJ_Underwater for getting a compile on the new Haswell DSDT, Toleda for patching and Rehabman for advice over on the DSDT thread.
I woke up this morning to a first HDMI DSDT - excellent.
Here are the results of me trying it.
DP on the NUC is port 6, HDMI is port 5. DP audio on port 6 is working with the DSDT and the following frame buffer, but HDMI audio over port 5 is not.

Very happy to report this change (i.e. change of connector type on port 5 from DP to HDMI) gives dual audio out now [HDMI on port 5, DP on port 6] - so both video output ports now working with accompanying audio.

Suggestion, edit only port 0x5 for the HDMI connector, port 0x6 is native DP.

HexEdit, HexFiend, etc.
Port 0x5 DP > HDMI

Agreed. I have edited my Framebuffer according to your simplified suggestion and all is good.



PS That DSDT is certainly one of the nastier ones I have seen. It was a great job for you and SJ_Underwater to edit it for compiling.

Hello

I don't understand what I need to do to get hdmi audio to work
Could you guide me a little to what to do with the contents in your posts minihack
Thanks in advance!

Okay,
It is basically all in Toledas guide.
You need (a)
The DSDT in your extra file
(b) If you have the native AppleHDA Mavericks kext (check by doing a right click on it and "Get Info" for version) and patch it according to the instruction Toleda gives.
(c) Patch the relevant frame buffer in AppleIntrelframebufferAzul.kext.

If you want a quick fix though just install the attached kexts as i have already patched them and use the HDMI dsdt.

Im probably doing something very wrong but with that dsdt in my extra folder OSX wont boot. So I have to boot the usb stick and go to terminal and delete the dsdt

Kind regards

Hmmm - maybe post your plist to check.

..and make sure you are using IntelAzulFB=10 (if you are using Chameleon).

Hi Toleda, minihack.

Thanks for the help with getting this working.

I'm trying to simplify it in my own mind, so I can add it to the install guide. My understanding so far to enable our HDMI audio is like so :

Require 3 tasks completing which are :

1. Clean compiled DSDT with HDMI audio patch applied
2. Patched native AppleHDA
3. Patched IntelAzulFB

To achieve this use the following files from your repository :

1. has5-dsdt-aml-8_series-nuc_compiler_fixes.txt
2. has4-dsdt-8_series_nuc_hdmi_audio-1.txt
3. audio_hdmi_hd5k-hda-90_patch.command
4. audio_nuc_hdmi_hd5k-azul-90_patch.command
5. audio_ssdt-hdmi-nuc_hd5k-amd-nvidia-1_v1.zip

And do the following :

1. Apply has5-dsdt-aml-8_series-nuc_compiler_fixes.txt to raw extracted DSDT and run compile command on it.
2. Apply has4-dsdt-8_series_nuc_hdmi_audio-1.txt to output of above and compile again
3. Install resulting DSDT file to /Extra
4. Run 'audio_hdmi_hd5k-hda-90_patch.command' to patch native AppleHDA.kext
5. Run 'audio_nuc_hdmi_hd5k-azul-90_patch.command' to patch IntelAzulFB.kext
6. Add SSDT-1 from 'audio_ssdt-hdmi-nuc_hd5k-amd-nvidia-1_v1.zip' to /Extra
7. DropSSDT in org.chameleon.boot.plist
8. Reboot

Is this the full and complete procedure to enable ?

I don't have an HDMI monitor/screen here so can't test it myself.

Also, would it be ok to include the above files as part of my Install Pack ?

Thanks.
