I have patched also my DSDT, and I'm getting a partial information in the System Profiler about the audio. It properly says the relevant info: speaker and microphone.

I use HDAEnabler, but it has some assertion errors when booting. I cannot see the message because it's flashing right before it goes to graphics mode.
Also tried to check in the system.log, but nothing. I guess it is because it is redirecting outputs to /dev/console (it says that earlier on).

I think, it should be close to getting audio output. I'll keep you guys posted on my progress.
