Could be either of those; It's been happening for a while, and both the
kernel and alsa have been upgraded in that time. I did try googling for
methods to rectify, but ended up with a lot of information, but little
in the way of solutions.

No sound devices have been added. Well, a webcam with mic, but that's
not what you meant, I know.

...as I also see greyed out references to the sound card, I decided to
try this first. Lo and behold, when I started the next KDE session, no
warning about sound card recognition, and checking the Phonon settings
page, no greyed out devices. So all is now working sweetly.

But being the crap typist I am, prone to errors, and also a certain
amount of guess work as to which were the working devices, and which were
the bogus ones. Although, if pushed, I'd guess at highest devicenum
being the working one.
Anyway, whatever was the correct device, I now have a working system,
and a method for correcting the problem again, should it recur.
Florian, you have my eternal gratitude for giving me the solution to
this problem. Your explanation has been added to my list of "how-to"
files.
Today I've had two issues resolved. This one, and my weird printing of
PDFs problem whereby they would only print in greyscale. Of course, the
printing issue isn't KDE relevant but eases my 'pain'.
Once again, thank you Florian.
