ALC3235 = ALC293 (PCI id 10ec:0293).

 

See the AppleALC wiki. All you need are:

  1. Lilu kext (which you should already have)
  2. its AppleALC PlugIn
  3. audio layout id 11 injected against the audio HDEF device (normally located @1F,3) in your bootloader's config. This will support built-in speakers + combo jack socket. 

HDMI audio will be supported if you inject HDMI type (i.e. 00080000) against connector con1 of the IGPU device (located @2).
