Hi Bronxteck,

The drive is indeed a better replacement for VoodooPS2, but my problem isn't solved.

My Dell has a Synaptics touchpad.

And I think the issue is with VoodooPS2Controller itself, not with the VoodooPS2Touchpad kext. 

And that patch Rehabman wrote for Dell laptops.  think same patch goes for Power button or may be also add the Power button the dell keyboard breakless Entries in info.plist of VoodooPS2Keyboard/Controller kext. The problem is don't know what is the code for the power key..

P.S. I have voodooPS2 inside my Clover.. That should not cause any issues.. but just in case..

Hi Jake lo,

I think I found what's wrong with the Sleep and my other keyboard related glitches.. 

In Karabiner EventViewer I am seeing infinite sequence of 2 key events(SysKeyDown followed by a SysKeyUp)..

Bellow is an output of Karabiner and attached is a photo..

I think the patch provided by Rehabman which applied the breaking keys hack to the brightness control should work for the power too.. but I don't know how to go about that

Thank you so much for the guidance.

I corrected the brightness button glitch with the help of this post by Rehabman, I took his Dell patch(SSDT-KEY-DELL-WN09.dsl) opened it in maciASL, compiled it and saved it as .aml File and upon restart the buttons worked as expected..

Now the only problem is instant wake one.. I have a TP-Link W725N nano wireless usb adapter for wifi connectivity on my usb 2.0 port(right). Even though I unplug it, The sleep is followed by instant wake..

Well when I try to send it to sleep it instantly wakes up..

P.S. My brightness hotkeys are also glitchy.(After Fn+f4/f5 they continue to decrease/increase brightness until the other key is pressed)

Thanks A lot my Audio now works... Do you know if anyone got sleep working on 3440 in el capitan?

How do I make that correction?

Okay Please let me know how do I do it..

is it like running all the commands except the last one?

sudo kextcache -Boot -U /

P.S. Do you want any modifications in config.plist shown ..

I read somewhere that the inject should be set and Audio ID should be set to 3.

Believe me I did.. 

Those commands the told me to execute..  ran each of them a ton of times.. I also ran the permission and cache build from kext wizard..

Here is a screen from the system report...

I am running OS X 10.11 (15A284) [/size]So no need for that kext right?..

kextcache updated critical boot files, requesting launchd reboot

kextcache is not giving AppleHDA, or CodecCommander in output.. is it normal?

I managed to get rid of this error but still no sound.. Basically I replaced my EFI folder and some kexts in LE with the files for 3440 in Post-2 here.
 
But even after all this I am unable to get the sound to work.. I also replaced the AppleHDA kext in SLE with the one from vanilla El Capitan installation SLE disk.

"The system extension “/Library/Extensions/AppleHDA_ALC283.kext†was installed improperly and cannot be used. Please try reinstalling it, or contact the product’s vendor for an update."

This error won't go, I tried the commands and every now and then they just won't work... could it be that the kext you've provided in the zip is only/upto supported on yosmite?

@Jake here you go..

EFI.zip

I noticed that the "alc283 kext not properly installed" error comes when the /L*/E* or /S*/L*/E* is changed.. and not on execution of the above command.. however now at random I am getting this error.. but this is random.

compress the clover folder and upload it here.

I don't have an option to upload..

@Herve I still the the not properly installed error after running the last command/statement

sudo kextcache -Boot -U /

tried multiple times.. same result..

I noticed there is AppleHDADisabler.kext in my /S/L/E should I remove it..? I didn't place it there.

No use.. no Audio yet...

I copied the kexts to /L/E. then copied the patches by Jake Lo.

But after some moments  got this error message.

The system extension “/System/Library/Extensions/AppleHDA_ALC283.kext†was installed improperly and cannot be used. Please try reinstalling it, or contact the product’s vendor for an update.

then two times

The system extension “/Library/Extensions/AppleHDA_ALC283.kext†was installed improperly and cannot be used. Please try reinstalling it, or contact the product’s vendor for an update.

and after repairing and building the cache and reboot still no Audio.

I followed the same on El Capitan for latitude 3440 but there still seems to be the problem with audio,, every other thing is working.. except the audio.. And the brightness control is strange.. its always at max on start and when in try Fn+f4(bright down) the brightness continues to decrease even if I press it once but stops to decrease once i press Fn+f5(bight up).
