Finally mod it with the stac7661 by changing the ids. now it's fully working, playing music on my vaio sz450n/c now.
for those who has the new vaio sz4, this is the audio driver.
use is with the appleHDA patcher, the patcher will crash for sure with the Semthex kernel, you need to replace it with the DaemonES kernel.

I tried this in osx10.4.9 and i get that this driver not found in taruga?? I have an SZ440

How i used this patch.. please step by step....

Use tha HDA patcher.

Vaio SZ450N ... Drag and Drop onto AppleHDA that file from topic - And no device found in system! WTF!

Sigmatel STAC9872AK @ Intel 82801GBM

I have vaio SZ330p/b, will this work on it?

Does your computer have "00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02)" because I have a SZ330P. Will it work?

I'm newbie. I cant use HDA patcher because i'm not see . Please help me about how to use HDA patcher.

I have fixed this for myself, if anyone needs help with this message me. I will explain exactly how to do it

My Intel PC uses the sigmatel driver, I can see the sigmatel high definition audio codec in the device manager in widows (BTW: I dual boot XP & Mac OS X on the same hard drive - works perfectly) but I have no idea which driver to use for Mac OS. Is this the right one? How do I instal it on the Mac?

I've only been using the Mac OS for 2 days (after a couple of days to figure out how to install). Expert on PC/Windows. Complete noob with Mac.

My laptop (Dell Vostro 1500) uses the Intel GM965 motherboard (82801HBM (ICH8-ME) south bridge)

Any help would be greatly appreciated.
