It's the integrated codec that counts, not the fact that it's Intel HiDef audio. In your case, codec is identified as 10ec:0283, i.e. Realtek ALC283. There should be existing patches for this. Look it up. Should consists of:

  1. a dummy kext containing the codec related definitions
  2. a set of 3 to 4 AppleHDA binary patches that you can implement either through Clover on-the-fly facility or through direct binary patching of the vanilla kext (but this will require to be repeated after every OS X/macOS update). These binary patches differ according to the target OS X/macOS version and it would seem you're on Mavericks 10.9.5.
