ROG Crosshair VIII Dark Hero - Audio Driver issue

[AsusExplorer]

I'm having an issue with my audio driver installation and this is driving me a little crazy, so any help is appreciated.
I can only get sound from my speakers if I disable the "enable audio enhancements" option in the Sounds/control panel.
The auto jack sensing doesnt seem to work, so when I plug in a headset to the front jack nothing happens.
The "Sonic Stuido 3" app installed but I notice the "Radar" app hasnt.
Also I cant find the Realtek HD Audio manager app, is that supposed to be present?

I feel like the audio driver installation is broken but uninstalling the devices from device manager and re-running the driver install is not fixing it.

Attaching a shot of my device manager with the relevant tabs, can someone who has this board confirm that these devices are the same as theirs?
TIA for your help,
