I'm a newbie on this, not sure if this's the link you're refering:
https://github.com/RehabMan/HP-ProBook-4x30s-DSDT-Patch/tree/archive/Resources_ProBook
Yes. Or clone the repo, then switch to archive branch (git checkout archive).

my model is CX20724, not sure:
1.which plist I should use (layout5 or layout7 ?)
Put both into AppleALC with unique layout-id values.

2.how to "importing the XML"
For that, you need to read the AppleALC wiki.
