OK, I made all the changes, mormegil, to AppleHDA.kext, including replacing 8508ec10 with 8308ec10. However, I still have no sound.

I noticed something interesting in my system.log, though:

9/6/09 11:11:55 AM com.apple.kextd[10] Can't load /System/Library/Extensions/AppleHDA.kext - no code for running kernel's architecture.
9/6/09 11:11:55 AM com.apple.kextd[10] Failed to load /System/Library/Extensions/AppleHDA.kext - (libkern/kext) requested architecture/executable not found.
9/6/09 11:11:55 AM com.apple.kextd[10] Load com.apple.driver.AppleHDA failed; removing personalities.

That's rather odd. I never changed any executables in the .kext file. Any idea what's going on, here? I'm running 32bit 10.6.

EDIT: I replaced AppleHDA.kext from my 10.6 install DVD, and that error went away. The failed sound assertions are back, of course, since this is a stock kext. I'm going to try putting the Info.plist files back, first, then hex editing the AppleHDA file, to see which broke it.

Thanks!

Thanks!
