MB Asus P5B Plus. I've tried many AD1988A/B kexts, but not one didn't work (because for 10.5 or i haven't other kexts as AppleHDA, or not right DSDT). May be this workink with original or patching AppleHDA and IOAudioFamily? Help to find working AD1988 KEXT for Snow Leopard (and DSDT with right HDEF). Please do not offer VodooHDA!

p.s. sorry for my English

I find and install AD1988.pkg for P5K http://www.mediafire.com/?gyr6tm72z6mbyc1
