Audio on EP45-UD3LR, Can't get audio to work Options

[DarkBond13]

Does anyone know any solutions to get the onboard audio to work on the Gigabyte EP45-UD3LR motherboard. I've tried ALC889a, ALC888, and HDAEnabler but I can't seem to get them to work.
Thanks in advance!

You can try this driver ,when can work you can remove ALCinject.kext and intall anther ALC889A/888 driver.

remove ALCinject.kext, AppleAzaliaAudio.kext, and/or AppleAC97Audio.kext in /System/Library/Extensions if you have.
use KextHelper to install HDAEnabler.kext and AppleHDA.kext into /S/L/E

My setup is running flawlessly with this board, but audio is illusive for me as well! Seems no matter which ktext I install, they all result in an unbootable kernel.

I know for certain this board uses the ALC888 not the 889, can anyone who has this same EXACT (Gigabyte EP45-UD3LR) board comment on how they got audio working!!

Did you try the DMG that is linked from the compatibility wiki page?

I just ordered this board for my install and this thread is making me nervous.

Has anyone had any luck getting this working?

My setup:

UD3LR Rev 1.0 with F5 BIOS
nVidia 9800 GT 512
E8600 3.33ghz
8GB Patriot DDR2 800

Retail 10.5.6 clean install updated to 10.5.7 before installing anything else. (EFI string for video and ethernet done before upgrade)

Chameleon 2 RC1 using /Extra folder off root (not the EFI partition but should work the same).

KEXTs in my /Extra/Extension1 folder are:
AHCIPortInjector.kext
AppleDecrypt.kext
Disabler.kext
IOAHCIBlockStorageInjector.kext
OpenHaltRestart.kext

KEXTS to get audio working were installed in the System/Library/Extensions folder using Kext Helper b7
AppleHDA.kext
HDAEnabler.kext

Both from this link 1.6.2a37 888.zip

I fought with it for several hours until I noticed that ALCinject.kext was in my /Extra/Extension1 folder. Removed it and recompiled the mkext in /Extra/Extension1 folder.
On reboot everything worked.

I should write a guide for this mobo as I didn't find one specifically for this board but using several guides and a little experimentation I was able to get everything working with very little "helpers".

James, that's awesome! I am very glad to hear it.

My parts should all be here by Wednesday:

• Q8400 2.66Ghz Yorkfield Quad Core Processor
  
• Gigabyte-EP45T-UD3LR mobo (not sure on the BIOS, but I assume it's rev 1.0 F5)
  
• Nvidia 9800 GTX+ (supposedly the EFI string for the 9800GTX works for the GTX+)
  
• 2x 1TB WD Caviar HDs
  
• 8GB DDR3 1066

You have the EP45T-UD3LR right? Would you do me an enormous favor and put together either a guide, or the modified kexts you're using? The mediafire link you posted for the audio kext is dead. I'd be happy to help you out on your guide given some of my specs are a little different (DDR3, for instance).

Thanks in advance!

I know this is obvious, but have you made sure you removed the old audio kexts you installed? Take a hard look through your Extensions folder to make sure. I remember when I had to get audio working my T61p, and after trying about 10 different options things were messy.

Sorry for the long bump but I also have a UD3LR and I came across this, and luckily I now have audio but unfortunately there is virtually no bass with the audio.

If I use VoodooHDA it works fine with bass, but it's buggy so I'd rather not have to use VoodooHDA. Do you guys also have a problem with bass? The sound is tiny and flat with the AppleHDA.kext...

I'm on 10.5.7 too by the way.

Edit: I fixed it. Just in case anyone else has this problem, all I did was install the Audio kexts included in this pack.

THANK YOU JamesDH for the pack!

The problem with that pack is that the AppleHDA.kext is a patched version of 1.5.7, which is kind of old

OS X 10.5.5 - AppleHDA.kext v1.5.7
OS X 10.5.6 - AppleHDA.kext v1.6.2
OS X 10.5.7 - AppleHDA.kext v1.6.8

Has anyone been able to successfully patch the latest version for ALC888 compatibility? There seem to be kexts based on v1.6.2 but I've seen nothing for v1.6.8

What's wrong with it being a little old? It works fine for me...
