272.18 (10.10.3 Yosemite)
Fully working. . Enjoy!
Audio Output:
- Speakers (EAPD) : Working
- Headphones : Working (With autoswitch when headphones inserted)
Audio Input:
- Internal Mic : Working (with ambient noise reduction)
- External Mic : Working (with autoswitch)
There are two methods to install (Choose any one):
1. Patched AppleHDA :
The only downside with this method is, you'll probably lose audio if you update from 10.10.3 to future updates because of new AppleHDA.kext with the update.
To fix either re-patch AppleHDA using simplified info i posted from
here or rollback to the attached patched kext.
Nothing to worry about though I'll provide support as long as i can.
Installation Instructions:
- Remove VoodooHDA.kext if installed. (S/L/E or Clover/Kexts/ or Extra/Kexts)
- Install AppleHDA.kext & EAPDFix.kext using your favourite kext utility in System/Library/Extensions
- Repair Permissions & Rebuild Cache
- Go to Clover Configurator -> Devices -> Audio (Inject) and set it to 3
- Reboot.
2. Using DummyHDA.kext and Kext patch using Clover:
The good thing about this method is you probably won't lose audio even after you update
from 10.10.3 to future updates
.
Installation Instructions:
- Remove VoodooHDA.kext if installed. (S/L/E or Clover/Kexts/ or Extra/Kexts)
- Make sure you have untouched vanilla AppleHDA.kext in S/L/E
- Install DummyHDA.kext & EAPDFix.kext using your favourite kext utility in System/Library/Extensions
- Repair Permissions & Rebuild Cache
- Go to Clover Configurator -> Devices -> Audio (Inject) and set it to 3
- Edit your Clover's config.plist and add the following patch to KernelAndKextPatches > KextsToPatch section
<dict> <key>Comment</key> <string>AppleHDA - ALC282 (1 of 3)</string> <key>Find</key> <data> hBnUEQ== </data> <key>Name</key> <string>AppleHDA</string> <key>Replace</key> <data> ggLsEA== </data> </dict> <dict> <key>Comment</key> <string>AppleHDA - ALC282 (2 of 3)</string> <key>Find</key> <data> hAjsEA== </data> <key>Name</key> <string>AppleHDA</string> <key>Replace</key> <data> AAAAAA== </data> </dict> <dict> <key>Comment</key> <string>AppleHDA - ALC282 (3 of 3)</string> <key>Find</key> <data> hQjsEA== </data> <key>Name</key> <string>AppleHDA</string> <key>Replace</key> <data> AAAAAA== </data> </dict>
Reboot. (You may have to reboot twice)
Why EAPDFix.kext?
EAPDFix.kext -> This is to fix no audio output after sleep.
You can also use (if you prefer) CodecCommander. Search for it.
