I can't get the audio of my Asus P6T (just p6t: no deluxe, se, etc) to fully work.
I know that it use ALC1200 (don't know if I have to use 885, 887, 889 etc)
I've tried several guide but I always have some problems:

1- Only OUT line is working, can't get my microphone to work.
2- When I insert my headset on the front panel the sound doesn't switch automatically, i've to manually set to use headset from Preferences. (Still only OUT is working)

Right now i'm using an AppleHDA.kext and at least I can hear sounds.

I've tried several HDEF patch to my DSDT but with no success.

I've attached my DSDT (clean verion, without HDEF) and the AppleHDA.kext that i'm using right now.

If you need other info just ask and i'l update my post.

Thanks for your help.

The ALC1200 is a rebranded ALC888. Attach a copy of IOReg. [Guide] How to Make a Copy of IOReg

You are not using a MultiBeast audio solution. Suggest backup your current system, a clean install, get to a bootable system (no audio), back that up, install MultiBeast/Without DSDT/Legacy ALC888. Reply with IOReg.

I didn't want to reinstall everything, so I've done this:

1- remove AppleHDA.kext
2- reboot and no audio
3- used multibeast to install Legacy ALC888 (without dsdt)
4- reboot: now I have audio with automatic switch speakers <-> headphones

Still microphone is not working.
IOReg says everything is working. Try Line In or Front Pink Port.
