For 892 onboard audio, see See Problem Reporting, Post #1, No Audio Devices - Realtek ALC AppleHDA. Post to same thread as the guide.

For HDMI audio, ssdt is working.
Display make and model? Connection?

If I am using HDMI only, is the 892 audio necessary? I assumed it is not.

Display is Monoprice MPLE27QPM at 2560x1440 via DVI-D. HDMI connection is to Marantz NR1403. HDMI Cable is connected at both ends, audio receiver was on when rebooting.

Hi Toleda!

Thank you very much for your help to get my onboard sound working! There's another pickle: HDMI through my HD 7770.

Motherboard: Gigabyte Z170-HD3P - latest BIOS - F5g
CPU: Intel Core i5-6500
Graphics: ASUS Radeon HD 7770 2048MB
Onboard Audio: Realtek ALC 887 (working! - thanks!)
OSX 10.11.2

I have a TV hooked up to the graphics card and I am using it as my main display atm. I only have 1 HDMI port on it (in case it makes a difference.)

What I have tried so far:
I tried following the easy guide. Got the SSDT for AMD, installed it to /EFI/CLOVER/ACPI/patched/

boot.log shows it's loading but HDMI audio is not present:
17:040 0:000 Inserting SSDT-2.aml from EFI\\CLOVER\\ACPI\\patched ... Success\
