Thank you very much, I just got this P43Twins1600 and I've tried manything to get the sound working. To many Codec dumbs to count, and this worked for me as well. Thanks everyone that has posted here.
My specs.
ASRock P43Twins1600
P43 MB
ICH10
Realtek 888
What's working: I get main speaker output along with 2 more, Mic and Line-in
Not working: everything else
I'm happy at this point to have anything, but mic was a bonus w/ line-in

I also spent many hours trying to get my ALC888 to work and I managed to get it working (using 10.5.2).
In Taruga's site, I downloaded the ALC888 kext file under the "
testing kexts" section of List galleries (the file id is 62). And then I also downloaded the ALCInject kext file. I then used the
kext patcher and when I rebooted it worked for me. I'm using an MSI P43/ICH10R chipset, so it may work for yours.
If ALCInject doesn't work, then try the HDAenabler kext on Taruga's website.
