FWIW, based on the kde3/arts and other previous "sound server" experience,
I've always been suspicious of pulse-audio, and have never enabled it here
(gentoo, so individual installation enabled/disabled, I've kept it firmly
disabled). Also, as it happens my hardware has native multi-stream
mixing, so I've not needed it for that, but even if I did, I think I'd
prefer alsa's own dmix or whatever it is, or just set the preferred app
active and not worry about the others, over a sound-server solution such
as pulse-audio.
So I've not had that issue here.
But what backend had you chosen for your kde sound output? Will running
something else piped directly to it (a xine based media player if it was
xine, something gstreamer based if it was gstreamer, etc) work, or does
that crash, too?
What about running as a different user with a clean config? Or
temporarily move your users homedir elsewhere so it's clean, and kde's
starting from default system settings? Does that fix it? If so, it's
something corrupted in your user settings and you can use the process of
elimination to narrow down the corrupted config file. If not, the system
config itself would appear to be corrupt.
FWIW, if it's found to be in your user settings, I'd suspect it's in
either $KDEHOME/share/apps/ or $KDEHOME/share/config/, probably in this
case, the latter, and one of the following files: kmixctrlrc,
phonondevicesrc, xinebackendrc (or the config file whichever backend
you've chosen), or possibly systemsettingsrc. Those are the ones I'd try
first, anyway. ($KDEHOME will normally be either ~/.kde or ~/.kde4 by
default, depending on your distro, I think ~/.kde is the default as
shipped by kde. ~ indicates your home dir, of course.)
