hy...everbody....i have installed on my k70io 10.6.3 combo update and hexedited AppleHDA.kext 1.8.4...just opet in AppleHDA.kext AppleHDA binary....use hedexitor and change 8508EC10 to 6206EC10 ( i 4 times) and put HDAEnabler.kext ( i use dsdt patch for HDAController).... put this modified AppleHDA.kext into S/L/E ..then use kext utility reboot and voila....sound is working....

and "click" sound every 5seconds is now gone with 10.6.3 update so this AppleHDA.kext has fixed my click sounds....

just a question: i have seen on other forum a guythat wrote a tutorial about dsdt patching and insert your pinconfig into dsdt so you dont need legacy k50io.kext...a have try to insert pinconfig...from my linux codec dump...in system profiler it shows that config but without patched applehda...sound is not working....have one solution to use dsdt patch for pinconfig in dsdt?

so when dsdt is loaded..it loads a hdacontroller patch and automaticly insert and patch applehda on boot...this will be great becuse on futher updates we will not lost sound again and we will not patch manually applehda.
