No internal microphone ASUS X550CA 10.10 ALC270

[pokiron]

Hi to all.

I would like to seek for your help because I can't figure out how to enable my internal microphone on my ASUS laptop.

Here's what I am using:

- Asus X550CA laptop (Intel Core i3)
- OS X 10.10 Yosemite
- patched DSDT (layout-id is 1)
- patched AppleHDA.kext for ALC270

I didn't used HDAEnabler since most of my audio ports and sound are working except the internal mic.

My audio codec is Realtek ALC270 and I am thinking that the audio layout could be the problem. This is the only problem that is keeping me from using my hackintosh on my laptop. I want the internal mic working as it should since I use it regularly.

I'm attaching my DSDT, patched AppleHDA and codec_dump.txt for reference

Any help pretty please??
