Hello All together ^.^)/

I have an Gigabyte GA-Z77X-UD3H (v1.1) with BIOS F18.

I installed OS X El Capitan v10.11.6 using Unibeast v6.2.0 and Multibeast v8.2.3
- running good

But i couldn't get the Sound ( VIA vt2021 Onboard ) working. All threads i found until now looks old and deprecated.

||| _Update_: I got it working - see the howto i added at the end of this posting.

System-Overview:

- CPU Intel Core i5 2500K / HD4000 gfx
- MB Gigabyte GA-Z77X-UD3H [v1.1] F18
-- Onboard SOUND: VIA VT2021
-- LAN: Atheros AR8161/8165
-- USB-3 : VIA VL800 chip (how to get them to work, too?)
- RAM 8GB Kingston HyperX LoVo DDR3L-1600 DIMM CL9-9-9 Dual-Kit
- DVD Plextor PX-L890SA DVD-Brenner
- SDD Samsung 850 Pro 256GB

+++ HOWTO: [VIA VT2021 Onboard-Sound]++++++++++++++++++++++++++++++++++++++++

|Pre:
1) You should have installed OS X El Capitan (v10.11.6) or macOS Sierra with Unibeast so that you have Bootloader Clover.
2) Note that Skylake systems may need the HDA ACPI device to be renamed to HDEF; this can be done with a Clover ACPI patch in config.plist. Or you have to use Toleda's SSDT https://github.com/toleda/audio_ALCInjection/tree/master/ssdt_hdef.

|What you need:
1) AppleALC (v1.0.16 or newer) https://github.com/vit9696/AppleALC/releases
2) Clover Configurator : http://mackie100projects.altervista.org/download-clover-configurator/
3) KextBeast (v2.0.1 or newer) https://www.tonymacx86.com/resources/kextbeast-2-0-1.310/
-- or: Kext Utility (v2.6.6 or newer)
4) Your AppleHDA ( System/Library/Extensions/AppleHDA.kext ) has to be original/native - if not, get a clean one from the OS X Installer : > Guide https://github.com/toleda/audio_ALC_guides/blob/master/Restore native AppleHDA [Guide].pdf
Don't forget to "force rebuild cache" after you replaced it with a native one by:
Code: 
sudo –s
sudo touch /System/Library/Extensions

|To-Do:
-- Changing Clover Settings --
1) Open Clover Configurator
2) Mount the EFI-Partition on your System Harddisk (click at [Mount EFI partition]
3) Click [Open Partition] and select in Finder EFI/CLOVER/config.plist
4) DoubleClick the config.plist file. Now you are in editing mode.
5) Change this settings:
a- Devices > Audio : write in the TextField the value 5
-- (info from here: https://github.com/vit9696/AppleALC/blob/master/Resources/VT2020_2021/Info.plist )
b- System Parameters > Inject Kext > Yes
6) Click the 2nd Icon(Paper with Arrow to right/Export Configuration) in the left corner of Clover Configurator
7) Thats it so far - close Clover Configurator

-- Installing AppleALC --
1) You have downloaded something like 1.0.16.RELEASE.zip and unziped it to the desktop so that you have there now a file called: AppleALC.kext
2) Your EFI-Partition should be still mounted because you mounted it with Clover Configurator.
3) Open Finder and copy AppleALC.kext to EFI/CLOVER/kexts/Other/AppleALC.kext
(There are other folders beside 'Other' like '10.11' - it will work there too for El Capitan if you copy it there but looks like not needed to make it so specific and AppleALC v1.0.16 is ready for 10.11 Sierra, too. So no worry about this.)

-- Final Step --
1) Restart your System.
2) After Restart open MacOS System Settings > Audio > Output : Choose the first Line-Out.
3) Open Youtube and watch videos with sound ;)

Thanks. This worked perfect for me with the same motherboard. Have been struggling to get this working for little over 6 months now. Especially wanted to call out your noob friendly instructions. Only thing I'm still struggling with is to get all the USB ports to work correctly (Only 2 in the back + 2 in the front work). Any helpful guide for this?
 
Thank you my friend, just installed Sierra on I7-3770k, 16gb ramm, this motherboard and gtx 660, audio running perfect!
 
This Guide Still works for me. Thank you so much.

I hope that this is not considered thread-hijacking but I wish to add, for the benefit of whomever stumbles upon this thread, that this guide worked for me on a fresh High Sierra install with my GA-Z77X-UD3H, though I only had to follow steps 1-7; I didn’t replace my AppleHDA with a native one (possibly because I was on a fresh install?) and had already installed AppleALC through clover MultiBeast.

Thank you for your guide, Toppa.ex!

are both front and rear ports working? Only my front ports are working
 
THANKS for this fix. It's taken awhile to find someone who noted the config.plist changes! and 'yes' both front and back speaker sockets work for me
