This is a known bug of hda_generic.c for those desktop with internal speaker and three audio jacks at rear panel (e.g. those lenovo
thinkcenter
with alc66x codec)
The driver prefer to assign volume control/dac to headphone, line out
and
internal speaker instead of line out and the other two multi io jacks
The workaround is to change the internal speaker as not connected node 0x15
Could you please advise how to do this? Is it possible from userland or
do I
have to patch something?

Would a new fixup mode definition for the kernel help and if yes, how
should
it look like, i.e. which pins should be listed? (I'm capable of
submitting a
kernel patch.)
or
You need to increase badness of multi io so that driver select multi io
as
the best config
I've found your patch from 2013 while googling for the topic. The current kernel already sets BAD_MULTI_IO = 0x120.
Do you mean to further increase it? If so, to what value, or is increasing possible from userland?
You need to increase BAD_MULTI_IO from 0x120 to 0x4120 since BAD_NO_DAC = 0x4000 for the driver to select config with mio=1
The driver seem to avoid the playback volume control shared by internal speaker, headphone and line out, this may mean that you need a suitable name for this volume control
