So, I hate to admit this - but I've been working on this a couple hours per day for the last week, and haven't been able to get my audio working. I have the Gigabyte Z97X-UD5H with the 1150 audio, and I've read every thread I've seen on the subject so far.
I've used the kext mentioned in this thread, installed it via Kext Utility and Kextbeast at different times, but whenever I restart, I get no sound and no visible audio hardware in System Preferences. I'm admittedly new to this scene, and really don't know what some of the other things I've seen are referring to, such as changing the "Audio ID". I don't know where that is, and nothing I've been able to find over the last several days actually comes out and tells me. Can someone clue me in on what I'm missing, or where to go from here?
I know the sound is enabled in BIOS, as it works just fine under Windows 8.1.
Here's my config.
Gigabyte Z97X-UD5H
Intel i5-4690
GeForce GTX 660Ti
16GB DDR-1333
Misc. pile of SSD's
VT-d is disabled, IGP is disabled, installed without DSDT's.
