I have no audio and I am new to all of this, but I've followed the steps and attached the file in a ZIP file. View attachment 48101
For an audio problem, post in the Audio Forum. Regarding your system, the wrong AppleHDA.kext is installed. Run MultiBeast 5.2.1 or newer - Select/Drivers & Bootloaders/Drivers/Audio/Realtek ALC8xx/Without DSDT/ALC898.

IO reg crashes or hangs on launch for me on 10.8.3 with Xcode 4.6.1 and IO hardware tools for 4.4.

This is my IOReg file attached below.
I want to enable Intel HD 4000 & AMD Radeon 7650M on my ML2 hackintosh.

Please help me. I am frustrated over a month. But, i don't want to give up.

Thanks in advance.

I recently updated to 10.8.5 via software update. Without doing any other modifications, I was able to restart without any KP, but audio didn't work. So I updated to ALC898 version 2.4.7 using Multibeast 5.5. Now, audio runs find for about 30 minutes, then starts to get progressively more and more grainy. If I stop playing sound for a while, then start playing sound again, the noise goes away, then come back again intermittently. Console does not display any sound assertion errors.

Attached here are the requested troubleshoot files. Please see my signature for system description.
