I'm trying to get my IDT audio working by patching AppleHDA like in leopard but it happens to be that Apple changed the structure of AppleHDA kext. So if anyone can help out please let me know.

I've got a working ALC662 AppleHDA from Leopard an i'm trying to transfer the patches over to Snows AppleHDA, if someone can help out, I attached the working AppleHDA from Leopard

i had this working in leopard just by hex patching AppleBCM575xEthernet.kext but, in Snow that kext is no longer there. i f somebody can help me out that'd be great

“I have never seen such an incompetent loser like OS_Ninja. This kid steal my work, and sell it as hims! He came into my #uefi-boot channel, talked some sh** about helping on development, with no idea what efi is, and after weeks of begging …”

“Check out Snow's thread. There's a link on how to inject by DSDT and how to patch AppleHDA. ok i did the DSDT method and everything works perfect. thanks alot. now all i got left is my 575x broadcom ethernet to get working”

“Are you using HDAenabler or DSDT to inject your audio? x64 hdaenabler but i'd like to try the dsdt method.”

“1.7.4a1 AppleHDA.kext (Snow Leopard) patched for IDT device id = 0x111D76B2 Hope it works it loads and shows this in system profiler: but no sound. in leopard it shows this: any idea whats stopping it?”

“I can try. I will need to know your full codec id too. ok thx heres my working leopard AppleHDA attached and my codec id is: and my config data is: let me know if you need anything else”

“1. Hex edit AppleHDA binary with your codec id 2. Edit Info.plist in AppleHDAHardwareConfigDriver.kext and AppleHDAPlatformDriver.kext 3. ConfigData goes into AppleHDAHardwareConfigDriver.kext 4. Layouts and PathMaps go into AppleHDAPlatfor…”

“oh nvm then, the Dell Mini 10v people have a method for getting our alc272 working with vanilla audio kexts: http://www.mydellmini.com/forum/mac-os-x-development/10965-building-100-vanilla-10v-starting-fully-working-audio.html but it only w…”

“Are you on amd because you need to patch the /System folder with marvin's amd patcher to be able to change the volume and mute doesnt work. no i'm on intel”

“What is your audio codec and what change of structure do you mean? my codec is IDT and i'm tryin to insert my codec verb, config id, and my node layout, bu the structure of applehda has changed since leopard.”

“have you tired using voodoohda? it seems to support alot of codecs. yes, thats what i'm using now, but its not very good becaus i cant change volume or mute it”

“Anyone figure this out? I also had no luck with VoodooHDA. I have a Bioastar TA780G M2+ motherboard with an SB700 Southbridge (ALC662). yeah, here try this. just install in e/e or s/l/e your choice. it says laptop injector but theres no dif…”

“download voodoohda.kext and that usually fixes most sound. with voodoohda the sound becomes distorted and crackling”

“just either try to instal that kext. or just wait for the new AppleHDA Patcher and re-run ur linux dump thru it first thing i did was ty this one but it kp'ed, thx”

“or u can use this fix from Zeph Mega Share.com/1579290 works for me every time”

“theres two ways to fix it 1. is to patch the kext to not check for the nvram 2. is to patch the getAdapterInfo part. other wise it fails to identify the adapter and unloads, ill need help to find the right parts to patch so if anyone got a …”

“after hex patching it with my dev id i get this during boot it looks like it can't access the nvram. how can i stop it from trying to access it and skip that step?”

“use this kext... Apple BCM 57xx: box .net/shared/iiygzhbk1x Only 32b but works perfectly ... ... ... thx but i'm looking for a x64 solution, i've tried hex patching the AppleBCM5701 kext but got a wierd error on boot”

“anybody got any ideas?”
