[ProBook 4530s] No Sound After 10.11.4 Beta Update

[demonknight9]

Note that if my README.txt is accurate, your 9470m is IDT 76e0 and therefore layout-id must be 17.

The PBI uses a single layout-id (12) for all IDT codecs and five different versions of AppleHDAIDT.kext. I decided to merge them into one kext and use a different layout-id for each codec.

You'll need to change your DSDT so it uses layout-id 17 instead of 12, install AppleHDA_ProBook.kext, and remove AppleHDAIDT.kext.

All done thanks mate. Sound is back
