Hey guys :) Hope someone can point me in a direction of some sort.

I have used Multibeast to get my PC up and working and so far everything is perfect, apart from this one issue.

When I choose the Realtek ALC889 Without DSDT option in Multibeast it goes and installs the two kexts (Optimised AppleHDA.Kext and HDAEnabler.Kext) then I reboot......

Issue

The machine boots to the login window but I have no response from my USB keyboard and Mouse (Wireless, Microsoft), it takes between 2 and 3 minutes before the mouse and keyboard will respond. On some occasions it can take well over 10 minutes but this is very rare.


No 2-3 Minutes doesn't seem a lot, but the actual machine boots in about a minute and it's annoying to have to wait another 3 minutes to actually use the thing :(

Why I think this issue is related to the Audio Kexts?

If I remove AppleHDA.Kext from the Extensions folder, the mouse and keyboard respond INSTANTLY upon boot.

What I have tried to resolve this issue?


  • The first thing I tried was a fresh install and the issue is apparent as soon as I have finished with multibeast.
  • I have tried installing VoodooHDA 2.7.4, this just caused the machine to KP :(
  • I have tried booting with the USBBusFix flag set - Same issue.
  • I have reset my BIOS/UEFI settings - Nothing.
  • I have tried using the newer version of Multibeast released yesterday - Same thing.
  • I have tried a different USB keyboard and mouse - Same issue.
  • I have tried searching google for hours on end and have come up with nothing.
  • I have tried going back to Windows - This is never going to happen :p

Specs

Motherboard: Gigabyte GA-Z68-D2H-B3
CPU: Intel Core i5 2500
RAM: 16GB Kingston 1333MHz DDR3
GPU: eVGA nVIDIA GeForce 210 512MB



I hate having to post in forums, because I like to get things fixed myself but I have come to an end and I really don't know where to go next.

I have tried reading about patching the AppleHDA.Kext file manually and unfortunately this has gone straight over my head, mainly because I am still fairly new at this :(

Any help whatsoever would be greatly appreciated and if anyone has an answer I would be really happy :D

Thanks :)

Your experiment is flawed. You only tested the presence and absence of AppleHDA.kext. The problem is not AppleHDA.kext; the problem is HDAEnabler1.kext. I don't know why the audio enabler interferes with USB on boot.

Solution is dsdt injection which eliminates the need for the enabler. Steps:
1. [GUIDE] Creating your own DSDT for most boards
2. ML: How to Add or Edit dsdt/HDEF

More info, Help me decipher -v output. Almost there but slow boot up at 1 point.

Thank you :) I have added sound with DSDT now and the machine boots quick and allows me to use the Mouse and Keyboard instantly :)

Don't wish to push my luck, but I have tried to enable encoded output on the Optical output but it is not working as it did before :(

I have entered these commands into terminal:


Code: 
[FONT=Helvetica]sudo perl -pi -e 's|\x89\x08\xec\x10|\x80\x08\xec\x10|g' AppleHDA.kext/Contents/MacOS/AppleHDA
sudo perl -pi -e 's|\x85\x08\xec\x10|\x89\x08\xec\x10|g' AppleHDA.kext/Contents/MacOS/AppleHDA [/FONT]
But I still don't have encoded output like I used to :(

Using these commands and installing the kext kills audio all together :(

Did you repair permissions and cache? What version is S/L/E/AppleHDA.kext is installed?

I repaired Permissions and I cleared the cache.

Version of the Kext is 2.3.1

When I reboot, System Information shows the same thing, all the inputs/outputs exactly as they were, but there is no audio.

Audio Preferences show no inputs/outputs.

I ran the commands again and rebooted, this time I have not lost audio but still see no encoded audio options in the MIDI options :(

IOReg is corrupt. The guide tells you how to created a valid file. Since you have audio back, attach the AppleHDA.kext you patched.

Really sorry....

No matter how many times I rebooted and fixed kexts and stuff nothing worked and I couldn't get the encoded audio working.


I have just had a power cut and the machine powered back on.... guess what now works... :p

I now have encoded audio working :)

Thank you Toleda for taking the time to look at my issue :)

One more thing to get working now is HDMI audio, but I shall try and get this sorted before asking for assistance again.
