Help - HDAudbus.inf not working, no DisplayPort Audio

Hello All.

I can't for the life of me get my surface pro 3 to play audio through display port in the dock and I have tried multiple docks, and just going to the DP out on it's own.

There is an error in the Device Manager for one of the High Definition Audio Controllers:

Device PCI\VEN_8086&DEV_0A0C&SUBSYS_0A0C8086&REV_09\3&11583659&0&18 had a problem starting.

Driver Name: hdaudbus.inf
Class Guid: {4D36E97D-E325-11CE-BFC1-08002BE10318}
Service: HDAudBus
Lower Filters:
Upper Filters:
Problem: 0xA
Status: 0x0

I've tried refreshing the driver, it says it's current. I have refreshed the PC no change. I can hear it coming from the surface but have no option in the sound controllers to have it come through my displaylink connection.

Running windows 8.1 enterprise, with the Jan. Firmware.
