Help me, I Can not modify layout-id to 99.

[kirbyzhou]

For using a special driver to get back the missing mute feature, I want to modify layout-id to 99.
So I edit my dsdt.aml, install driver, reboot.
But when I take IORegisterExplorer to check, the layout-id never changes, it always be 1.

Anyone can help me?

Delete S/L/E/HDAEnabler1.kext, repair permissions and cache

dsdt/HDEF/layout-id is correct.

You are great!
I finally get it work now. And the mute feature of ALC887 is OK now.
