ALC272 on Snow Leopard, Using an AppleHDA that works with ALC272
 

I have an AppleHDA kext that works with ALC272

I installed it using Kext Helper on Snow Leopard, and it works on the first reboot, but once I restart the system again, I get a kernel panic.

Any ideas? I'll try to put up the error code in a sec

You need to patch SnowLeo's AppleHDA.kext or get a patched one that works, doubt the ones from Leo work in Snow...
Using VoodooHDA is always an (easier) alternative if it works for you.
