So this combination is not supported so far right?

I've been trying to get sound to work for days. I extracted the 887 kext from the latest Multibeast and it was installed successfully to the System/Library/Extension folder. I executed the audio_cloverALC-110.command and it found the 887 kext and successfully patched the AppleHDA.kext. When I rebooted I have the similar problem to the above poster. I can adjust the volume on the desktop, I go to the Services and Sound, and it appears that the mod worked in that I can select different output lines, however, I do not get sound from the speakers. I've tried the audio_realtekALC-110.commandand the 887 legacy kext. I've tried various combinations of 887, 887 legacy, audio_realtekALC-110.command, and audio_realtekALC-110.command, replacing the AppleHDA.kext with the original copy during each patch attempt. So far no luck. What else should I be looking at or is my setup too old for El Capitan?

El Capitan 10.11.2
Gigabyte GA-G41MT-S2PT board
Intel Core2 Quad Processor Q9450
8GB DDR3 GSkill 1333 Ram
Crucial M500 SSD
Intel®G41 + ICH7 Chipset
Realtek ALC887 audio codec
1 x Atheros AR8151 chip (10/100/1000 Mbit)

Luck has nothing to do with working audio. Not one of the methods you used above will result in working audio. Suggestion; pick one method and execute each step exactly. All methods required native AppleHDA.kext. Methods: Post #1, Realtek ALC AppleHDA; use 887 Legacy.

Front panel problem or mic problem.
Mic on rear input does not work as the pink becomes orange output with Audio ID: 2.

Hmm, but under Windows Mic on front panel works without problem. Strange. What you have set in BIOS for Front panel - HD audio or legacy AC97?

 

[toleda]

HD audio or legacy AC97?

One choice, HD Audio; OS X does not support AC97.

Yeah, I also thought so... so you are using "audio_cloverALC-110.command", Audio ID: 2 and Mic on Front input is OK. What can i have set differently than you? Any idea?

Yes.
What mic? What are you trying to do with the mic?
