After a lot of trials finally I was able to get my speakers, headphone and mic working. Special thanks to The King, without his guide it wouldn't have been possible. Thanks to Taruga also, who explained how to find correct nodes from Linux dump.
Anyone having the same motherboard can use the attached kext along with original AppleHDA.kext (should not be removed) to get audio working. I am also attaching the screen shots of my audio preferences.

Full Version: Audio injector for Intel DG33FB (ALC888)
i have the same hardware as yours and installing audio was one of the easiest things for me. I took hardly 15 minutes to do so after installing Leopard for the first time.
I used AppleHDAPatcher v 1.18 and dropped ALC888-a, ALC888-D and ALC888-b in it and rebooted. Even mic (and headphone) was working though I have never used mic again. You can find the three files in the attachment.
