Apple HDA ALC269 is not working in Yosemite 10.10.2

Question

Hello guys

Yesterday I have updated my laptop to the Yosemite 10.10.2
 
My notebook:
| Acer e1-571;
| 4GB memory;
| Intel hd 4000;
| WiFi Atheros 9285;
| ALC269
 
But when it rebooted, after the updating, did not have more audio :(
The strange thing is that it identifies the audio inputs on the system: /
 
I can not use the voodoohda because it leaves me without a microphone, so I need a patched Apple HDA.
 
 
Note: in 10.10.0 and 10.10.1 the patched apple hda worked properly
Note 2: I have the DSDT patched to run on ALC269 and still does not work (it worked correctly in 10.10.0 and 10.10.1)
 
Sorry for my english
