Sorry for not responding earlier, here's the dump. Codec is an IDT 92HD81B1X5.
So the first zip attached is the patched 10.10.4 AppleHDA from Mirone's github page (https://github.com/M...ppleHDA_10.10.4). I think it'll still work in 10.10.5 but don't take my word for it.
It doesn't appear that you're external mic/line in is enabled in it though so I took the 10.10.5 AppleHDA, implemented Mirone's config to it, and made a few changes to enable it (2nd attachment).
You should have 4 devices: internal speakers, headphones, internal microphone, and external microphone (line in).
All of those devices except the internal mic are EAPD devices so you'll probably need to use EAPDFix or CodecCommander in addition to this patched AppleHDA to get those to work properly.
Try them both and let me know how they work. I believe that all but the ext mic should work with mirone's assuming 10.10.4 AppleHDA will work in the 5th update and hopefully all 4 will work with mine
Btw, layout id = 3 in both kexts for any hdaenablers you're using (or dsdt or boot loader)
