Alright!
So the newest Unity package is missing the OVRVolumeControl.
Here is a version that "works" with the current package. It won't show the volume bar if you're already at max/min values, because the event that the button was hit appears to be missing so you can't key off it here.
I added the LastVolumeInput, TempVolumeInput and TimeToCheck values so it tracks when the volume has changed. There was some minor changes made to the Update function as well.
Add this behavior to the prefab with the missing script.
Add that prefab to your camera.
Position it where you want it to appear in the users vision.
Blamo - it'll work.
Cheers!
