Sigmatel Audio on XPS M140?

[Hatorade]

I've installed 10.4.6 JaS (with sigmatel patch) on my XPS M140 laptop and I'm having trouble fixing the sound. I've tried Wiki's sound fix tutorial and no luck. I've also tried:

 

sudo -s

<type your password>

cp -R /AppleAC97Audio.kext /System/Library/Extensions/

cd /System/Library/Extensions/AppleAC97Audio.kext/Contents/PlugIns/

kextload AppleAC97AudioIntelICH.kext

(at this moment, it should load without error)

rm /System/Library/Extensions.kextcache

kextcache -k /System/Library/Extensions

 

(doesn't load AppleAC97AudioIntelICH.kext: says there's a problem with the permission)

 

then I tried:

 

sudo -s

<type your password>

cp -R /AppleAC97Audio.kext /System/Library/Extensions/

chown -R root:wheel /System/Library/Extensions/AppleAC97Audio.kext

chmod -R 755 /System/Library/Extensions/AppleAC97Audio.kext

cd /System/Library/Extensions/AppleAC97Audio.kext/Contents/PlugIns/

kextload AppleAC97AudioIntelICH.kext

(at this moment, it should load without error)

rm /System/Library/Extensions.kextcache

kextcache -k /System/Library/Extensions

 

(the kext loads correctly but still no sound)

 

 

Is there any way to fix the sound? I know a lot of people have gotten their sound to work on their Dell Laptops with the sigmatel sound, but no luck for me.
