Pietruszka Posted April 11, 2010 Share Posted April 11, 2010 Hi with 10.6.2 I've used alc662.kext + original applehda+ dsdt but now with 10.6.3 this kext doesn't work someone with this motherboard ????? thanks for any help Link to comment https://www.insanelymac.com/forum/topic/215309-alc662-and-1063/ Share on other sites More sharing options...
inaba178 Posted April 12, 2010 Share Posted April 12, 2010 would you share alc662.kext and dsdt files ?my card have no sound yet .maybe i can learn something from ur kext Link to comment https://www.insanelymac.com/forum/topic/215309-alc662-and-1063/#findComment-1447002 Share on other sites More sharing options...
el_charlie Posted April 12, 2010 Share Posted April 12, 2010 Hi with 10.6.2 I've used alc662.kext + original applehda+ dsdt but now with 10.6.3 this kext doesn't work someone with this motherboard ????? thanks for any help You have to use the original AppleHDA from 10.6.2. DSDT editing doesn't do anything for 10.6.3 yet. My mobo (Foxconn G31MV-k) has that codec, too. I hope someone makes a better patch to use the current vanilla kext. Cheers!

tangon Posted April 26, 2010 Share Posted April 26, 2010 Hi my friend @el_charlie I saw your signature. You have the same motherboard as like me. Is it possible to tell me how you fix the Audio Realtek ALC662 in 10.6.2 snow. Can you explain me about "working with patched DSDT + 10.6.2 ALC662.kext and who can I find all that? Thanks you.

TennisGeek Posted May 21, 2010 Share Posted May 21, 2010 just deleted AppleHDA 10.6.3, used 10.6.2 and it works no changes with dsdt don't know if I still need alc662.kext in Extra... must check this thanks for help With ALC662.kext (or LegacyHDA.kext for alc662 out there. They are the same.) AppleHDA from 10.6.2 does work. In other word, Apple managed to break ALC662 for 10.6.3. Good job Apple. Looking at the ioreg when it's not working, it looks like it wants to work. All sorts of entries are attaching to the HDA, but it does not. It's more likely some kind of tweak is needed in acl662.kext, than it's a total bust. -- TG Link to comment https://www.insanelymac.com/forum/topic/215309-alc662-and-1063/#findComment-1472767 Share on other sites More sharing options...

TennisGeek Posted June 10, 2010 Share Posted June 10, 2010 If the driver code checks the actual PCI registry or chip's register for matching rather than letting IOKit's default driver matching to work, DSDT patching would not help. Many drivers use IOKit's matching method since you don't need to write any code to do so, but some drivers override the behavior. So, don't be surprised that your attempt does not work. -- TG What if we use the DSDT to tell OS X that we have the audio device with ID 885 and the other stuff remains unchanged???

You can place the ALC662.kext on your /Extra/Extensions directory and locate the HDEF section of the DSDT an apply it to your own DSDT. The AppleHDA.kext must replace the 10.6.3 kext in order to get sound. I looked on IOREG that all the values on the DSDT have been loaded, so, editing the codec id in the DSDT could work BUT the same codec id must be changed on the dummy ALC662.kext because its data is loaded too. In theory, we can get sound for the ALC662 codec if we must make OS X to think that is has a suppoted codec (ALC889 for example) plugged in but injecting its own configuration. Cheers!!
