acer e1-572 audio,brightness

[horuszp]

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?

Both audio and brightness are covered in the FAQ.

Thanks, for brightness it solved problem.
But for audio, how can i detect which chip i installed? or somehow get deviceid of my soundcard? i will try more with alc282, but not sure that it is right.


Nevermind, i found it in previous link. i need to sleep a bit) Thanks again.

hmm, still got problems with sound. Detected that have ALC282, tried all applehda variants, clover audio injection,dsdt, hdaenabler, pached applehda, dummyhda. Both versions of ALC282, v1 and v2 applehda. but still no luck

Only use ACPI patching for layout-id inject and IRQ fix. See ACPI patching guide: http://www.tonymacx86.com/threads/guide-patching-laptop-dsdt-ssdts.152573/

removed clover injection, removed HDAEnabler,
only left injection in DSDT layout-id is 3, and applied patch IRQ fix to it.
AppleHDA get from http://www.insanelymac.com/forum/topic/298663-applehda-for-yosemite/ checked both v1 and v2.
Here i see that kexts load but audio



And here what i see in system report and in sound prefpane. Audio still not presented in input/output

kextstat|grep -y appleintelcpu returned nothing, all other in archive.

Your kextcache output shows that patched AppleHDA.kext is not installed.

Awesome. In last time i forgot to move it to s/l/e and only move to kexts of clover.
One more little question. is there way to enable mic of builtin webcam? as i see cam work fine. but in sound there is no input for it.
And even if i connect headphones with mic to audio in mic not work too.

Update:Found. As i understand i can patch applehda. will try then. Many thanks.
Soon when will finish with mic will make complete guide for my laptop.
