How to get Sound working on your Gigabyte GA-EP45-UD3P

Please download the attached the kext and EFIstudio then follow the steps below.
Hope you will also get sound on your GA-EP45-UD3P

1. Delete the previous applehda.kext at /System/Library/Extensions and any other sound kext you may have installed. Do nothing on a fresh install.

2. Download attachments and copy kext to /System/Library/Extensions

3. Apply the kexts using

CODE:
sudo -s
(password)
cd /system/library/extensions
chmod -R 755 * && chown -R root:wheel *
cd ..
rm extensions.mkext
kextcache -a i386 -e
then restart

4. Run EFIStudio

5. Select the device type as HDEF, then click the add device button, it should have automatically inserted a whole bunch of code, then click the add to the boot.plist button

* You may also need to add your Display Adapter. I know your adapter is working at the moment, but mine quite as soon as I got the sound working. I simply used EFI Studio to add my Display Adapter to the boot.plist and everything works great.

6. Restart

7. If sound is working on your Gigabyte GA-EP45-UD3P you are done. If not go to System Preferences / Sound and Select Internal Speaker Type: Built in Speaker as you primary output. I know that you don’t have a built in speaker, but OS X thinks your green audio out is an internal speaker.
