Thank you so much! Recording side works also great now.
The only remaining issue seems to be that the Auto-Mute Mode control
has no effeect on speaker muting. It is always muted.
The speaker mute button on the keyboard also mutes the speaker, and the volume buttons unmute it.
The Beep volume also works, but Beep mute only affects the treble content of the beep.
And then the most important part: in proc file, both Dock connectors are described as black,
and the Dock Mic location states "at sep Left", while it should be "sep Rear" I believe.
If you need to test anything else on X200t, or T420, I'll be happy to help.
Thanks once more!
With best regards,
