Audio and Bluetooth driver issue on AsRock Z170m iTX/ac

Hey guys,

I booted safely into Sierra 10.12 through Multibeast, and after the driver installation, my audio still doesn't work. Also Bluetooth options are no where to be found.

My system is running on an AsRock Z170m iTX/ac (supported by the buyers guide here) with an 6700K, 16 GB of RAM. No dGPU.
I have connected the system to my monitor via DisplayPort.

Any solution to this?

Thanks a lot.
