Thinkpad X1 + OneLink+ dock - audio not available after docking

[Marc Olson]

After docking my X1 Carbon (4th gen) with the OneLink+ dock, neither the headphone jack on my laptop, nor on the dock work--only the laptop speakers work. As a workaround I created a script to reset the audio preferences after I dock (attached: fix-audio). This moves all active inputs to the dock and sets the dock as a default, but seems to be a bit heavy-handed.
