Hi, all. I've uploaded to Ms Skydrive. Please find the link below.

A good way to reduce the possibilities of KP/Sound assertion:
If use Chameleon, pls put this AppleHDA.kext under /ext/extensions, then drag the folder"Extensions" to kext Utility2.3. You will get a new extensions.mkext. In this way, the chance to cause KP on boot is reduced to 1/15. Then reboot.
If use bootthink, put it into /Darwin/System/LibrarySL/Extensions/, then drag the folder"Extensions" to kext Utility2.3. You will get a new extensions.mkext. Reboot.

Once again, please share if any one have ideas about Line In SoftwareDSP.
