Kernel Panic after trying to fix audio (10.6.8 Supp. Update)

[Yoru]

I installed 10.6.8 Supplemental Update, audio crashed, tried to make a rollback but installed another audio kext by mistake, I don't remember. Now I got a Kernel Panic when I boot, and I can only boot in safe mode.

I would like to know how can I uninstall all the audio kexts I could installed, and if I can make audio work with 10.6.8 since I have been doing some research and seems that it is causing some trouble.

I know that was a stupid mistake but it was too late and have been coding too much hours.

Here is my mainboard:
Gigabyte EP45-DS3 (ALC889a)

I've been getting a few kernel panics on booting. Plugging in headphones or a cable into the rear output seems to work !? I'm a noob and have only had mine running for a few days, but it might be worth a try..
