Mavericks: HDMI Audio - AppleHDA [Guide]

[toleda]

I attached this kext that worked in 10.9 and 10.9.1. However this kext works on 10.9 and 10.9.1 only when HDAenabler is installed (no onboard audio, but HDMI audio works).

Clarify, 662 onboard: yes or no?
If no, see ML: How to Add or Edit dsdt/HDEF, edit HDEF as shown in Post #1.

Toleda,

I used the Nvidia Kexts and my audio kexts from 10.9.0 and i installed in 10.9.2 and the HDMI sound worked again! No issues found. It seems there is a driver issue in 10.9.2?

I attached the 10.9.2 IORegistry with 10.9.0 audio and Nvidia Kexts.

Thanks Toleda for your help!

You misunderstood, my 662 question is, are you trying to get 662 onboard audio to work in addition to HDMI audio?
Regarding HDMI audio in 10.9.2, your dsdt has an invalid layout-id. The enabler sets the layout-id to 12, valid, and worked in 10.9 and 10.9.1. Normally, the enabler interferes with HDMI audio and it finally caught up to you. Edit the dsdt/HDEF as noted previously. Reply with edited dsdt and IOReg with native 10.9.2 kexts.

Sorry, my english is bad sometimes. I'm not trying to get 662 onboard audio. I just want HDMI audio working.

I did this DSDT when i had a Nvidia GT 430. Would that be the reason for invalid layout-id or i misunderstood?

I'm confused in this. The topic ML: How to Add or Edit dsdt/HDEF looks like i need patch my dsdt with correct HDEF, right?

Thanks for your help. I ask patience with me
