No HDMI audio after 10.9.2 update

Thanks but there is no hdmi fix for 898 in this repo

You are right; no such fix. What are you trying fix with the 898?

Attach the dsdt and ioreg.

Well after a lot of reading I also tried MaciASL + your patches for changing layout-id but still no HDMI audio.

Also, after using the MaciASL patched DSDT, onboard audio started working without HDEnabler BUT I noticed a lot of slowdowns during OpenCL effects suchs as screensaver, windows minimize-maximize, etc.

I am attaching the patched DSDT + ioreg output.

How did you manage to attach an IOReg with HDAEnabler1.kext installed?
Let's make this simple: HDAEnabler=Yes, HDMI audio=No.
The dsdt attached is not the dsdt installed for the attached IOReg.
HDMI audio dsdt edits have no effect on graphics performance. Every native Mac ships with HDMI audio edits.

Reply with the correct dsdt and the correct IOReg.

I have a z77 Ud5H with Nvidia GTX670 and it was perfectly working setup including HDMI AUDIO until last minute of 10.9.1 as from 10.9.2 update it lost hdmi audio. (I am using the multibeast ALC898 WITH DSDT) It seems like some people fixed it by re-editing dsdt again with your patches. thank you

No effect. There are no 898 HDMI audio dsdt edits, there are HD4000 HDMI audio edits.
Attach your IOReg.

HD4000 is disabled, nvidia is your only choice. Attach the dsdt.

The dsdt and the IOReg are different. Verify the attached dsdt is installed. Restart and make new IOReg. Attach dsdt and IOReg.
