I would put this on hold until further notice. Probably me not understanding pulse-audio settings correctly. After a lot of fiddling and wild guess it would work, stop with some other settings, and stop, when removing the tablet part off the convertible.

Now my sound is mum. It is kind of visible, but not as speakers in the tablet part of my convertible. So when removing the tablet from the dock, there is no sound. Shouldn't be a hardware problem, since W10 (dual-boot) plays musics. (The files are with dock attached, since the tablet on its own has - and that's a bug of *buntu - no right click. So the 'USB ....' shown as audio device is the device in the keyboard dock.)
