[GUIDE] How to port AppleHDA to SL

[blkhockeypro19]

Hey guys. I patched my DSDT properly and followed the guide with no trouble. On reboot, I get these errors:

Any idea what the problem is? It's a stac9227 kext from leopard.

Well, do you have sound?

Hi, all

I followed this guide and patched the original AppleHDA (snow leopard edition). Every time I reboot I see the sound assertion as below.

Some times, I could get kp, failed to get into SL desktop, and had to reboot with -v -f and managed to get into SL and got working headphones, internal speakers, line out(automatically switch), but can't record. After that, I can reboot normally and get into SL, but sound assertion in logs.

If I intalled any new kexts or ran kextutility, in next reboot, I would get a kp same as before.

Attached are my patched drivers and code dump from linux and pinconfigurations from windows.

Anyone can help would be much appreciated. Really need working recording.

Are you running 32/64 bit SL? Which bootloader are you using? Also, have you patched your binary?

Looking at your dump and the KP symptoms I'm assuming you have a laptop. You don't have a working kext do you? Patching from scratch? If so, this guide is not meant for you. The one you're looking for is here.

Your plists seem to be in order though. Maybe you just need to trim your Configdata, Layout and Pathmap a little. You seem to have too many ports mapped out for a laptop.

[ping99]

Hi, mormegil. Thanks very much for your help.
Yes, it's a loptop CQ60-202TX, and running 60bit Snow Leopard, using Chemeleon 2RC3. I also have tried PCEFI 10.3 but it didn't help. I patched binary AppleHDA by replacing 6202EC10 with 5150F114(linux dump:0x14f15051). I also tried replacing others as in this thread mentioned with 5150F114, but the same result.
On leopard, I have a patched working kext(no recording) and just followed this guide to import to SL. I just learned dump from linux and use codegraph & verbit to get verbs, but don't know how to manually put layout and path map, could you tell me how to?
Thanks a lot.

[mormegil]

So your problem is not actually related to this guide since your old kext is not fully functional to begin with? I'm afraid I can't help much in that regard since patching from scratch involves a lot of trial and error.

You will have to try out different port mappings by following king's guide and see for yourself if it works. Try to reduce your configdata to only include the minimum number of ports for basic usage OR you can try searching for a good kext which works in leopard so you don't reinvent the wheel.

Also, avoid using chameleon rc3 if you're on 64bit since it doesn't have fully working 64bit efi support which leads to sound assertion errors during boot.

[ping99]

Hi, Mormegil. Thanks for your prompt reply. I will follow your advice to figure it out.
