you can use Appleazaliaaudio.kext for Output, a small usb-soundcard (Terratec AureonUSB) for Micro if needed. This will prevent the cracking noise during startup (if USB is used for Output) and the sound assertion errors in verbose mode.

Hello, I have this problem: I have a Sony Vaio laptop VGN-AR41M and a Realtek ALC262 audio device onboard. I have Iatkos 10.5.7 installed and using AppleHDA patcher and ALC262 dump codec text I have no problem to get sound. I'd like to use Snow Leopard and I tried to follow this guide to use my working AppleHDA Leopard kext in SL, but I have no success. I've injected my DSDT file and I thinks it's ok. In System Profiler, under audio section, I have the sound card output recognized. But under preferences sound I have no output at all.
Could you help me, please? Is there anyone with Realtel ALC262 working under SL with patched AppleHDA?
Thanks in advance!

Do you know what would it be the problem? Thanks in advance!

I tried another AppleHDA version and I get a different error:

Any little help?

Hey... Glad to hear that there is a possibility for my lost sound in snow leopard

I have a fully working applehda in leopard 10.5.8.
after installation of sl (10.6.2) my sound is gone, so i followed the instructions and did everything like in this thread but it doesn't work. I use hdaenabler + applehda in my leopard and it works very nice. i downloaded a hdaenabler for sl and installed it with my patched applehda for sl - no luck

can anybody help me please?
Here is my working applehda from 10.5.8
