Hey guys i finally got my 10.5.1 to work on my pc, the only problem I am having is my audio. I have a sigmatel 9220 sound card for my dell dimension 5100. I followed the directions below but everytime I try the Fourth line i get rm: /System/Library/Extensions.kextcache: No such file or directory.

1. Download AppleHDA.kext from 10.4.3 (attached in zip format).
2. Copy to /System/Library/Extensions/ and replace original (backup would be a good idea).
3. Open Terminal
4. Type "sudo rm /System/Library/Extensions.kextcache"
5. Type "sudo kextcache -k /System/Library/Extensions
6. Open up Disk Utility
7. Choose the "Repair Disk Permissions" button. It should start up. It may or may not fix things... Mine didn't repair anything, but I did is as a precaution.
8. Reboot.
9. Open up System Preferences/Sound to confirm audio. I have both output and input, but I have to check inputs.
10. My audio is coming out of the subwoofer port (black). I would try all of them if it doesn't work with black.
"

after this i wanted my hi def sound working, so i can across this page

- http://forum.insanel...showtopic=32859

and downloaded the HDApatcher v1.16, then went to

- http://psykopat.free...apple/AppleHDA/

and downloaded the codec dump named "codec_sigma9220.txt"

i put the HDApatcher in System/Librarys/Extensions then dragged and dropped the codec dump file on the patcher icon, followed the instructions and rebooted once it told me to and hey presto, i have the audio comming out the green terminal

let me know how yous all get on

Any ideas of why i get that error or any other ideas in general on how to fix my audio?

Thanks much

There is no such file in Leopard (the guide was made for Tiger). Use Extensions.mkext instead:

sudo rm -rf /System/Library/Extensions.mkext

But in Leopard that is not even necessary. It will rebuild the cache automatically upon restart.
