I've been following a guide but am unable to get my audio to work.
The guide I've been following is here: http://tonymacx86.bl...or-onboard.html

In my extracted DSDT, there is no HDEF device. So I just guessed and copied a working ALC889 HDEF to my DSDT. It compiled, but when I restarted, I still didn't have working audio. I just noticed that there is no AppleHDA under System Information -> Extensions. So it's either that the kext isn't loading or the DSDT is incorrect (or both).

I just want to get 2 channel audio working, and I don't care how I do it. Attached is my DSDT.

I got audio working with voodooHDA, but there is a distinct and annoying hiss coming through (actually it sounds awful...). I would really like to have it work through the above method. Any thoughts?

Buffer (0x28) {}

Buffer (Zero) {}
