Damn. I guess I should have waited for your reply before doing anything crazy. I've just completely over-estimated the complexity of this.
Do you know if there's any way to fix this mess by perhaps booting off the Snow Leopard disk or booting with the 10.6.4 update mounted to a USB? Or even by copying over the System/Library/Extensions folder (as well as the .mkext file) from my MacBook?
You can re-install the 10.6.4 combo update to refresh your S/L/E folder back to vanilla. If you have 3rd party kexts in there you can just delete them, install that update, repair disk permissions.
You could also just start all over. Personally, I keep my Chameleon install and Extra folder on a 1GB partition of my main drive so that I can re-install the OS without ever having to re-install drivers. (Granted, now that Apple has messed with sound so much you always need a bin-hacked AppleHDA.kext)
Hey guys - I'm having some very strange problems and would appreciate any advice in terms of how to fix it, or how to at least better diagnose the issue.
Here's my build:
Gigabyte GA-X58A-UD3R Rev 2.0 (FA Bios)
EVGA 9800GTX 512 MB
EVGA 9800GT 512 MB
I'm using most of the fixes from this thread and I've recently put the 0.2.2 VoodooHDA kext in my /E/E folder. However, every now and then I'll get some pretty serious audio distortion (it sounds like my CPU can't keep up with playing the audio). It'll crackle and pop and skip. Sometimes, video/Flash will also have problems when this happens. I'm not exactly sure what causes it (Time Machine, USB Webcam, Skype don't seem to have a direct correlation with causing it). No meters are going crazy (in iStat) like HD use, network, CPU, memory - everything seems pretty calm.
I've also removed the AppleUserUpstream kext to fix the jumpy mouse problem.
I used the Kakewalk 2.2 SL disk method to install.
Why are you using VoodooHDA? It is not a good sound solution and frequently causes these types of problems.
Use the files already in this thread to have working audio. You need:
an edited DSDT
modden AppleHDA.kext (use kext utility)
You will also need to delete Voodoo.
I am very interested in buy a GA-X58A-UD3R board.
I'm concerned about the Rev. 2.0 due to all the kext installs. Does the Rev 1.0 board work completely "out of the box" so to speak with the Kakewalk installer? The thread on the forum says its supports the X58A-UD3R motherboard. I assume perhaps only for the 1.0 version? can anyone confirm that 1.0 boards do not have any audio or ethernet issues with this installer?
Except for ALC889A audio chipsets, all motherboards require hacked or modified AppleHDA.kexts in order to have working sound. That includes the rev 1.0.
The kakewalk method should work completely at the time of install, but every single update you will need to use kext utility and drag a modified AppleHDA.kext on top of it in order to have working audio.
It might be best if you just learn how to do a USB install since methods like kakewalk don't actually teach you anything. You remain completely ignorant and helpless after an update or any change to your system. Something will always go wrong and you would be better suited learning how to fix it now rather than later.
