Public bug reported:
The 3,5mm jack of the ThinkPad USB-C Dock Gen2 does not output any
sounds.
The USB Device is 17ef:30d1 Lenovo ThinkPad USB-C Dock Gen2 USB Audio
On the software side everything seems normal, I see output controls and
everything.
As soon as this USB is passed through to a Windows VM and back, sound
works.
A quick look in snd-usb-audio gave no clue and I have no idea how to
debug such things, but Windows seems to do some magic when initializing
this device. That Initializations seems to be persistent until powerdown
