Please disregard my last message.
I amended the x200t-pincfg file with [codec] section and added [pincfg] header, now it works much better.

In Rec screen of Alsamixer all three mic volume and boost controls are present.
Autosensing of Dock Mic works, and so do its controls. Internal mic works too, but
autosensing of Ext mic does not.
(Internal Mic Boost is so long name that it does not want to fit in its space)

In Playback screen the three Mic Boost controls are present, which is perhaps not necessary.
There is also an Auto-Mute Mode on/off control, which does not seem to do anything.
The headphone sensing and controls work as expected.
