Obviously backup kexts you need.

: AppleHDA_ALC1200_HDEF.zip ( 1.7MB )
remove AppleHDA.kext from /S/L/E and install this after dsdt edit.
HDEF code is attached in the zip pack, put the HDEF code in:
- SCOPE _SB

older 10.6x versions:
- SL 10.6.2 modded kexts

- Snow Leopard 10.6.0 and above ALC1200 audio kext:

I think latest ALC1200_SLIM version could be considered "final", I'm running 10.5.6 and I'm working on this OSx version.
For previous OSx version you can try installing only the ALC1200fix and the HDAEnabler from ALC1200_1056LINEIN version and see if that works.
The other ALC1200 kext versions out on the forum are old and I think can even cause some shutdown/reboot issue.
This driver doesn't work with ALCinjector.
- SPDIF coaxial Digital Out working
- Headphone working
- Line in is working only in the slim and line-in version, read notes down this post
Works on 10.5.7, just download and reinstall the driver.
Choose driver version, I think best choice is the slim version:
1. Update (4th june 2009) slim version from 10.5.7 applehda with: green line out, headphones, rear mic, line in and spdif out
I removed not needed verbs for multiple channel output (I don't need them)

4th june 2009 10.5.7 version [latest]
ALC1200_SLIM.zip ( 805.01K )
[/b] 19th april 2009 10.5.6 version (discontinued)
2. Normal version with no line-in, you can switch between front/rear mic without any trouble
ALC1200_1056.zip ( 819.55K )
3. This is a beta version with all three input working, line-in, front mic and rear mic, front-mic has some trouble
This version works but if you switch between inputs, front mic stops working (only for that session obviously, if you reboot it works). This happens because ALC1200 has 1 digital mixer node for 2 channel (linein and front mic) instead of one, so if you come back from line-in input, to front mic, front mic stops working.
At the moment I would think this driver can't manage thing like this, so I don't know if we could have a better driver than this.
Anyway I wanted a working line in and if you select this and use it, that works, so if you need line-in you should use this version.
Update (14th april 2009) with RCA spdif in "about this mac"
ALC1200_1056LINEIN.zip ( 823.28K )
Update (17th april 2009) removed ALC1200fix.kext from the pack
ALC1200_1056_LINEIN.zip ( 810.61K )
If you're updating your driver, in order to install this, remove ALC1200fix.kext from your extension folder, then install this with kexthelper.
Now in sound preference there's no (useless) "Internal speaker" "Built in" for input and output.
