there's no audio at all in there or even a reference to the hardware address it should be at. Can you enable audio in Windows and then extract it using Everest from Windows?

use a app called Everest, it has a free trial, choose option from lower left corner of it's window t0 extract DSDT. once extracted, post it back here. Or boot into OSX without DSDT in Extra folder and use Chameleon Wizard's DSDT tab to extract there, must be booted without using a patched one though.

ok, btw to attach files, in OSX zip them first by RT clicking and choose "compress" from the RT click menu, then click "more reply options" to upload. It's picky about file types so gotta zip pretty much anything that's not a picture and remove any dots from the file name other than .zip

yeah, it says don't :) at least not with what I was doing. if it turns out thats the only way to make it work, so be it. But should be last resort, it causes kernel panics and is too unstable

anyway, if its 888 or 889, got you covered either way

have you installed the corresponding appleHDA.kext using Kext Wizard? Also after installing, use kext Wizards repair permissions and rebuild kernel cache options, then reboot. DSDT install is right though

first appleHDA I posted was for 889, 2nd one was for 888

and Voodoo must be removed first

kext wizard available here http://dl.dropbox.co...d/download.html

OK, having some browser problems, let me try that again....
Trying to verify that your audio is located at the usual hardware address, lspci will show all the devices on your PCI bus which includes your audio. Download lspci, http://www.mediafire...qtsqxaz3nux6gsj install it and restart. Then from terminal the typically used command would be: lspci -nn
We're going to use: lspci -b -nn
this will show the true hardware address of the devices and not just what OSX sees. So here's and example of what is needed:

here, we can refine our search results with the power of grep

Attached File  fishgrep.jpg   117.94KB   48 downloads

The 00:1b.0 seen there, would be 0x001B0000 in DSDT like this:
		    Device (HDEF)
		    {
			    Name (_ADR, 0x001B0000)
			    Method (_DSM, 4, NotSerialized)
			    {
				    Store (Package (0x04)
					    {
						    "layout-id",
						    Buffer (0x04)
						    {
							    0x79, 0x03, 0x00, 0x00
						    },
						    "PinConfigurations",
						    Buffer (Zero) {}
					    }, Local0)
				    DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
				    Return (Local0)
			    }
		    }
	    }

And is the address I used in yours as it is usually at that address, but since that address was completely absent from your DSDT, would be best to double check.
