Atfer some blind trial and error attempts there is now sound again on
the dock´s 3.5mm jack.

I played with samplerate options in daemon.conf and after setting these
values, sound was there again:

avoid-resampling = yes
default-sample-rate = 44100
alternate-sample-rate = 96000

Before that, values were vice versa, default to 96000 and alternate to
44100.
