For some time, I successfully installed OS X 10.5.2 and 10.5.6 on my laptop and other computers I've built but I never installed OS X on an AMD build before but it works and now I am trying to fix some few problems. I am worrying about the video problem later since I just bought an ATI 4850 card from newegg and its coming tomorrow since there is no support for onboard graphics ( i have ATI HD4200 intergrated graphics). Here's my build:

AMD Phenom II X2 550 Processor running at @3.6Ghz (overclocked it and it works since i get kernel panics on stock settings...weird)
G.Skill 4GB Ram 800MHz
Gigabyte MA785G-UD3H -ALC889A audio
SATAII DVD Drive
SATAII 1TB Hard Drive
SATAII 250GB Hard Drive

It took me a while, but I was able to install the iDeneb 1.6v 10.5.6 lite edition since that was the only one that worked. I used the ALC889a driver that came with the iDeneb installation and it worked. The only problem is that theres this weird crackling/static noise everytime I open up and play a song on itunes or play a video on youtube. I also noticed that the video speed on youtube increased and breaks up and the playback speed on itunes was painfully slow and broken up. I was using the Voodoo 9.5 kernel but I am now using Qoopz latest kernel thinking that would fix the problem but nothing. I also tried:

-The ALC889a.pkg fix
-The GA_ALC889 fix
-remove ALCInject.kext
-Using CMI8738PCIAudioDriver.kext with AppleHDA.text (and tried patching it with ALC889adump.txt)
-LegacyHDA

So right now I am stuck! I really don't want to give up on this because I am so close! A little help please?!
