But can even USB-C accept a signal input (keyboard and mouse for
instance) and unrelated signal output (audio for instance) on the
same physical socket? I ask only out of curiosity.

The setup is rarely tried.  Appears that nobody can reply.

A keyboard or mouse sends tiny amounts of data; a few bytes per
second. In principle the link should be able to fit that in without
significant drop-outs in audio output.  WIth so many details involved,
a general answer is difficult. When all else fails, we can test and
see what happens.  =8~)
