The /usr/bin/startkde script references /etc/sysconfig/sound, which
doesn't exist (on my system, at least, and sndconfig doesn't create one).
The result is that kaudioserver and kwmsound are not started,
regardless of whether there is a soundcard in the computer. I think that
the needed file is /etc/sysconfig/soundcard.
Moreover, sndconfig puts a localized comment to the start of
/etc/sysconfig/soundcard (LANG=cs, LC_ALL=cs_CZ), which
somehow confuses bash, so that
.: /etc/sysconfig/souncard: cannot execute binary file
appears in .xsession-errors and the CARDTYPE variable is not set
either. Putting a line of
at the start of /etc/sysconfig/soundcard fixes it, which IMHO should be
done by sndconfig alone.
Thanks for the time you spent with it.
