Help with Yosemite HP envy 6 installation

[pocchio]

Hello,

 

I have an HP Envy 6 -1070el 

 

- i5 3317U

- HM77

- Intel HD 4000 

- AMD 7670M

-Audio IDT 92HD91BXX

 

I've managed to install Yosemite using Chameleon but I'm having trouble patching DSDT I hope someone can help me.

I'd like to disable AMD Radeon , patching for Brightness (I don't have the slider), AppleHDA patched (I've found that with layout id =0 i can see something in system report but no audio devices output).

 

I'd like also to have a functionally sleep because battery is really important to me but since now i couldn't manage it.

 

I've attached a clean DSDT and my org.chameleon. boot file

 

Hope someone can help me.

Thanks
