Headphone jack not working.

[LJAM96]

Just setup my build on a Windows 10 / macOS dual boot. The system is:
Motherboard: Gigabyte GA-Z170N-WIFI
Graphics: NVIDIA GTX 1070 FE
CPU: Intel i5-6500
After installing macOS Sierra 10.12.4 and running Multibeast and installing the audio drivers of Realtek ALC1150 as a guide based on my motherboard had said but upon rebooting I only the sound option on 1 of 3 of my monitors and my Oculus Rift. No headphone jack audio. any ideas where I'm going wrong?
(The guide followed was for El Capitan if that makes any difference)
Thanks
