Help Galaxy Book (Backlight)Audio)

Running osx El Capitan on a Galaxy Book 12. I5 7200u HD620 (Audio ALC298) OLED Screen What Im hanging are Audio and Backlight. i have tried so many ways and now im tryiing patched DSDT with Brigthness ACPI 100 FIX, and ACPIBacklight.kext in clover/kext/other. Fn keys and sys display slider works like a charm, but no backlight changes.

Also for audio Tried apple alc lilu with layout 13 and also some ways with Apple hda, or clover hda with hdef patch, fn keys and slider works, but no audio.

How could i fix?? Thanks
