Do i need the unpatched one? Because i just patched my AppleHDA thing with that patcher a while back and then i went back to Azalia?

And i had no sound at all when i installed OS X. When i installed it i never chose a audio driver either. Later on I installed the Azalia driver first, then patched my audio with AppleHDA patcher, then went back to azalia.

now that i think of it, no you dont need to upload your vanilla AppleHDA.kext. i forgot that i ripped my AppleHDA kext straight from the iATKOS dvd. so just upload your patched Info.plist. as for the 5570z, did your internal audio work when you first installed OS X?

[Reign Of Terror]

hmm...safari wont let me download that. it downloads and then it says "this file has moved since you downloaded it" try zipping it, and then uploading it here.

Just found out how to zip files lol

[Reign Of Terror]

try this out. it might not work for you seeing you said sound never worked in the first place, and if thats the deal, you may need to upload your Info.plist from after you use Azalia as well so i can get your CodecID from it.

Didn't work for me. What do you do when you said you chmodded and chowned?

i dont see why it wouldnt work. i checked your AppleAzaliaAudio file, its the exact same Codec as mine. go into terminal, type the following:
sudo -s
(type your password)
chmod -R 755 /System/Library/Extensions/AppleHDA.kext/Contents/Info.plist
chown -R root:wheel /System/Library/Extensions/AppleHDA.kext/Contents/Info.plist
diskutil repairPermissions /

wait for that to finish, when its done, type "exit" twice, reboot. remember that the speakers should only work once you highlight Internal Speakers in you sound settings.

[Espionage724]

Repairing permissions now.

EDIT: Still nothing....i have sound through Headphones but nothing out of Internal Speakers.

Could it be possible that when I use HDA patcher, the nodes that are identified for the speaker...could they be wrong?

[Reign Of Terror]

hmm yea... it was just a shot in the dark that it could possibly work for you, seeing as you never had working sound to begin with. your Azalia info.pllst looks exactly like mine does, so i have no reference as to what your CodecID is for Azalia... and im not sure which files the Azalia driver patches, otherwise i'd just have you go in and give me a bunch of Info.plists im pretty sure that the HDA Patcher patches AppleAzalia, ALCInject and AppleHDA. as theres a change in ALCInject once i used it, but its really of no use to me anyways... you're absolutely positive that when you install the Azalia driver that gives gives you internal sound, that there isnt a AppleHDA.kext in your extensions folder? it would make it so simple if there was...

[Espionage724]

Umm....I could go check again....if i reinstall my azlia driver would that be able for me to verify if there is a applehd.kext in my extensions folder?


In my Azalia driver installer I see this:

This package will install the AppleAzaliaAudio.kext in /System/Library/Extensions/ and will move existing AppleHDA.kext, ALCinject,kext and AppleAzaliaAudio.kext to /AzaliaBackup folder in the root of your drive. You do not need to repair permissions, just reboot when asked and you should have sound output on the following chipsets:

[Reign Of Terror]

ok awesome. patch with Azalia, reboot, and post up your AppleHDA Info.plist. hopefully it will have some information i can use to help you out.

[Espionage724]

[Reign Of Terror]

hmm... thats the same file i just gave you. Azalia must not have patched it at all... im not sure what to tell you Espionage. i'll take a few more looks at these files in the morning and see what i can come up with.

[Espionage724]

K...well before you go to bed...if you dont mind waiting...ill try installing azalia drivers from my leopard cd just to see if that changes much.

[Reign Of Terror]

sure, i can wait for that. hopefully it gives me what ive been looking for.

[Espionage724]

nope stil no AppleHDA.kext in my extensions folder....I;ll keep experimenting with stuff I guess.

Wait do you have your linux codec dump still? I could try patching with that to see if anthing happens.

[Reign Of Terror]

try this out. if it works, try installing that Info.plist i made you.

Still no luck...

[Reign Of Terror]

no idea then man... im just happy i finally got mine working the way its supposed to.

[Espionage724]

So in windows you have a Realtek High Definition Audio card?
And in Mac you have a Intel High Definition Audio Card?
And your codec is ALC883?
And you have working Headphones, Speakers, BUilt-in Mic, Mic, and Digital Output?
