Hi, I tried to patch that myself but I can't really get it to work. 
I'm the kind of person who prefer doing things themself but... 
  
well, I ask you for help 
  
I tried the files you patched for N53SM (I have an N53SV) as well, mic works but I can't hear anything 
  
with my dsdt AppleHDA doesn't load at all, and I can't understand why as HDEF seems patched correctly. 
  
thank you 
  
EDIT: Forgot saying I'm on ML
