Hi all ready 4 days and today 20 hour I sit on this laptop without success, So is some one who can help.

So try a lot of method one of them work little bit and after restart stop. Other work only mic without internal audio. 
So I try all acl269 variant from here.

I try from here
http://www.insanelymac.com/forum/files/file/496-applehda-patcher/
all 10 variant from AppleHDA patcher
so I understand that from every one have clover method and direct replace AppleHDA in /S/L/E I try it bought again no luck.
so I have other problem who can not make sense. 
I use program DPCIManager and sometimes they see Audio devices sometime not recognize it.
wen is hapen I start to change CsrActiveConfig 0x67 / 0x3 . few times and few restart till recognize audio devices
I upload my last config.plist again no success.
so I not have any audio kext in /clover/kext/Other 
and any ideas about problem ?

There are a wide variety of laptops with ALC269 

and each one of them with a different revision, which leads to a situation 

unique to each, although some may work with the same kext, other not 

that is the your case, so I suggest that you post your codec_dump+config.plist+IOREG,

if you do not know how to get these files, google is your friend, or just search here on the forum how to do this.

I have a Lenovo L420  and it has ALC269Q codec, so I use AppleALC kext with layout id 4 in my DSDT. All works except internal microphone, which only records noise, i have absolutely no idea why, but you can try my suggestion to  at least get some audio output, from Mavericks to Sierra
