What case are you using. What is plugged in what audio jacks?

Try this experiment:
1. Play a song in iTunes.
2. Plug you headphones into the front geen jack
3. Select System Preferences/Sound/Output/Headphones
4. What do you hear?
5. Make a new copy of IOReg.

Reply with what you hear and the IOReg.

4 :can not hear anything

In 4, is nothing different than the "noise" previously?

Another experiment, run MultiBeast 5.2.1 or newer - Select/Drivers & Bootloaders/Drivers/Audio/Realtek ALC8xx/Without DSDT/Optional 3 Port Audio and restart

1. Play a song in iTunes, select the AirTunes icon, verify computer
2. Plug your speakers into the pink jack
3. Select System Preferences/Sound/Output/1st Line Out
4. What do you hear?
5. Try the other jacks
6. Plug your speakers into the blue jack
7. Select System Preferences/Sound/Output/2nd Line Out
8. What do you hear?
9. Try the other jacks
10. Make a new copy of IOReg.

Reply with results and IOReg.

Front jack is not working. Does audio work in Windows or Linux? I don't know why OS X audio does not work on your system.
