I'm on OSX since 10.5 and 4 laptops to date, but this one is a pain.
I have a sloppy, but working Clover based 10.11.1 on HDD, but since I just bought a SSD drive, I decided to start from scratch, looking for latest solutions.
I found an excellent guide for similar device, but audio does not work.
I do have a semi working patched AppleHDA, v2.5.3 by Mirone (attached), found somewhere years ago, but in the past I had some issues after wake (seems ok now) and audio through HDMI does not work.
Thing is that apparently my ALC269VC is somehow a very rare thing manufactured by Sony, I can't really find any proper solution.
I thought that someone could help me doing this properly once for all, using DummyHDA to persist stuff between updates.
