Hi, i have two problems with my Yosemite install.
1.Brightness, i enabled QE/CI on my hd4400(deviceid 8086:0a16) on i3-4010U with http://www.tonymacx86.com/threads/fix-intel-hd4200-hd4400-hd4600-mobile-on-yosemite.145427/ and fixed 9mb buffer too from this post. But maximum brightness of screen too low. How i can fix it?
Updated:
Firstly i installed acpibacklight.kext but nothing changes,absolutely nothing. Tried to change brightness via BrighnessControl app from app store but it maximum value and almost minimum are same.
Then I found RehabMan manual for brightness fix via DSDT. got DSDT via clover, uncompiled(automatically via maciasl), applied 2 patches
"Rename GFX0 to IGPU"
"Brightness Fix" but not "Brightness Fix (Haswell)" because there was no changes when i selected it
After that i see brightness slider in display prefpane but changing it from minimum to maximum didn't change brightnes at all. How i can increase my brightness, i don't even need slider, just want to set it to maximum by default.
Update2: Also found in ssdt, make 2 patches, rename and brightness fix (haswell),
there found haswell. But still prefpane slider do nothing. And maximum slider position still very low.
like this
2.Audio, i didn't remember which realtek i have installed and can't found any documentation for notebook to found right deviceid, i found some posts on forum for e1-572G, that mention that alc282 installed, tried couple kexts and patches but still have not sound. How i can check which deviceid for sound i have? or which audio chip installed?
