Mountain Lion: MultiBeast - No Audio/Solutions and Problem Reporting

[toleda]

Should we post in another thread or in this one? Anyways, I installed the combo update, installed with DSDT ALC 889, rebooted, and my audio is greyed out.

You have the same problem as the others, no AppleHDA. Do you or did you have S/L/E/GenericUSBXHCI.kext installed? At this time, the only solution may be a clean 10.8.5 install.

Would you recommend trying a new clean installation or do you see a way to fix the problem?

I don't have the GenericUSBXHCI.kext installed. Is there anyway to restore the AppleHDA from a backup? I have a recovery partition installed. Also, I tried to install my AppleHDA from a time machine backup using Kext Wizard, but this didn't work. Thanks for the help.

Yes.

At this time, it is proven the problem is not the kext; the native AppleHDA.kext shows the same symptoms. Restore your backup. When you did the 10.8.5 Update, did MultiBeast complete successfully or with an error?

-I have the same problem with AppleHDA.kext not loading
-multibeast never failed for me on numerous attempts
-update was performed w/downloaded combo update, no through software update

Your first clue there is a problem is the missing orange (sub, center) and black (rear) ports on the motherboard.... That is not an OS X problem. There is an OS X solution, set Audio ID to 2. More info, see Mountain Lion: Optimized AppleHDA for Realtek ALC8xx and one or both of the Downloads/pdfs.

Regarding the front mic and headphone problem, that is a hardware problem (case, connector, motherboard, HD Auio only, etc.)

I don't know what causes the problem nor do I know at this time how to fix it. Once the problem occurs, the choices are: 1. restore 10.8.4 back up or 2. fresh install of 10.8.5.

Thanks, man! You helped me to open my eyes - I have not orange or black ports on my mobo. All was I need - install HDAEnabler2.kext (optional for 3-ports motherboard).
Front ports still no working, but it not important for me.
