Ah, this last one can be marked as checked, suddenly noticed
that graphical terminal generated "nice" alarm just resounded
unexpectedly :-)

Sadly, this snd_pcsp appears to be a prerequisite and it is
not loaded automatically in this Fedora Rawhide installation
and with this audio HW (~ no out of the box experience,
not sure where to forward this after more testing, cannot
immediately as it cannot be unloaded for being in use).

The noisy sound will only appear when a separate (not
present unless snd_pcsp is loaded) PC-Speaker (Master)
channel gets unmuted.  Maybe I even confused cause and
effect about this, it's all, well, confusing, so sorry
if that was the case.
