Try this:

AppleHDA.kext/Contents/PlugIns/AppleHDAHardwareConfigDriver.kext/Contents/Info.plist/IOKitPersonalities/HDA Hardware Config Resource/HDAConfigDefault/10/ConfigData

Change ALL the first HEX value to 3. For example 21871C40 to 31871C40.

If that doesnt work, try 0. For example 21871C40 to 01871C40.

I certainly will !!

But I just tried that app and copied in the HDEF fix, and for the first time EVER I managed to compile a DSDT.aml, zero errors !! (first mpart exactly like you did, second with the missing code that Snow has and I dont that I "complained" about before")

Look what turned up.

Let me just reboot back with vanilla then Voodoo...

New dsdt with both your address 2 and 3 patch bring back "your dsdt" mappings, except audio ID read 889 not 12.

What do you say, keep trying this new dsdt or the one you made?

going to attempt your latest suggestions on your address 2 patched kext...

Mormegil, sorry, got confused. trying to follow your path... after info.plist, I open with text edit and only find

Code:

<key>CFBundleVersion</key>
	<string>1.7.4a1</string>
	<key>IOKitPersonalities</key>
	<dict>
		<key>HDA Platform Resource</key>
		<dict>
			<key>CFBundleIdentifier</key>
			<string>com.apple.driver.AppleHDAPlatformDriver</string>
			<key>CommonPeripheralDSP</key>
			<array>
				<dict>

Slighty confused, because I cannot find the rest you mention

Sorry. I've fixed the path. And use my dsdt pls. The one you created is useless. I know it shows up all nice in Sys Prof but you're basically telling it what to show on the screen. I doubt you really have all that ports on your laptop. Showing up in Sound Preferences is all that matters.

ps. that dsdt app is bloody awesome!

Delete the kext from folder, then go to spotlight and write "disk utility", choose system drive and click Repair Permissions.

I followed the steps on Page 1 but I noticed that I have more sound coming out of one speaker than the other. I only have 2 speakers an a subwoofer. Does that sound normal or am I doing something wrong with getting the ALC889a to work?

Please help me out guys, i will be very thankful

I was wondering if anyone could help me figure out how to fix the audio on my Snow Leopard 10.6.2 install. My hardware is listed below. I tried using VoodooHDA, LegacyHDA and modified AppleHDA. The best I can get is either the Back speakers to work or the Sub and Center speaker to work. I would like to enable the 5.1 sound, as I have the speakers connected via 3 pins to the PC. Based on what I have read in this forum, there might be hope for me yet, but I need some guidance.

If you need additional information please let me know and I will provide.
