ASUS H97i-PLUS HD4600 issue - my monitor still not a HDMI sound output

[alamusi]

ASUS H97i-PLUS with onboard audio ALC887, and ethernet i218
Intel core i5-4660 with onboard HD4600

Yosemite 10.10.2
Clover EFI boot
Built-in speaker output is fine (except wake-up no sound issue)

Then, I followed [Guide]_HD4600-hdmi_audio_(dsdt_or_ssdt)_v2.1.3.pdf
1. AppleHDA.kext (toleda/audio_CloverALC)
2. AppleIntelFramebufferAzul.kext (toleda/audio_CloverHDMI)
3. ssdt (toleda/audio_CloverHDMI)

Everything looks good but my monitor is still not showing up in the sound output list...
DPCI Manager shows both HDA and ALC887/888b

System Info shows both HDA and ALC887

as well as HD4600 and my monitor (connected via HDMI)

but I can't see the monitor as HDMI sound output?


I attached ioreg export, config.plist and SSDT.aml.

Thanks in advance!

Attach dsdt and debug/boot log

Thanks toleda for the quick response!

I am DSDT free but here is the one I extracted with the boot log from DPCI Manager.

Is it possible this issue is related to BIOS onboard audio setup, or monitor?

Thanks!

No, the ssdt is not working.
HDMI audio dsdt edits will work.
The HDMI audio edit results in one error, delete:

Awesome! Thanks toleda! That does the trick!

Just being curious - why the SSDT approach didn't work in this case?

Hey alamusi, if you see this—

I'm looking into a build for my mother with the H97I-PLUS and integrated GFX. Which file exactly did you edit according to toledo's instructions? Thanks!
