[Solved] Intel NUC HDMI audio

UPDATE: For solution, see Post #25 of this thread for [Easy_Guide] ML_hdmi_audio_edits_intel_nuc.

This is a new board out from Intel that has HD 4000 Mobile 384MB graphics. The HDMI out is the only built-in audio out and I'm having some trouble getting it going. Here's my copy of IOReg

Is it something like D33217CK or D33217GKE? Are the graphics and ethernet working?

Why are you using the 09 framebuffer? Reply with the dsdt. [GUIDE] Creating your own DSDT for most boards

It's a D33217GKE and I do have ethernet and video working. Will upload DSDT tomorrow when I get home.

Here's my current DSDT. The reason I'm using the 09 framebuffer is because I don't quite know what the hell I'm doing.

Any tips/solutions you want to propose for this machine I will happily implement and test. No HDMI audio or sleep are showstoppers for me and I really want to get those working.

HDMI audio experiment:
1. Delete S/L/E/HDAEnabler1.kext, repair permissions and cache
2. Verify native 10.8.2 AppleHDA.kext installed in S/L/E
3. Remove efi injection from org.chameleon.Boot.plist.
4. Install attached dsdt.aml in /Extra
5. Restart with HDMI device connected.
6. Verify HDMI audio

Reply with new IOReg.

I did a quick reinstall with the bare minimum and placed the DSDT in /Extra and the audio doesn't work. The card is recognized and the graphics are fine though. "Intel High Definition Audio / HDMI/DisplayPort Output" also appears in the system profiler.

Here's the current IOReg. There's no EFI injection in cameleon.

What HDMI device is connected to which port? Does your version have 1 or 2 HDMI ports? If 2, attach another IOReg with the HDMI device on the second HDMI port.

Can you tell us which mSata SSD and/or wifi/bluetooth parts did you use. I'm thinking of doing the same.

Thnx in advance.
