I have disabled artsd now in KDE by starting kcontrol -> Sound &
Multimedia -> Sound System -> Unchecked "Enable the sound system". After a
reboot I verified that artsd was not running anymore.
Still, I do not hear any sound though, when running aplay or play.
# /etc/init.d/alsasound stop
Shutting down sound driver: /etc/init.d/alsasound: line 163: 2896 Segmentation fault /sbin/rmmod `echo $line | cut -d ' ' -f 1`
ERROR: Module snd_seq_midi_event is in use by snd_seq_oss

done
When I try again it hangs (also aconnect --removeall hangs then).
Perhaps this is because the alsa sources 1.0.12.rc1 I installed myself
have overwritten the .rpm files that I had installed before. There might
be version conflicts, I have no clue how to check that.
# rpm -qf /etc/init.d/alsasound
file /etc/init.d/alsasound is not owned by any package
The mixer properties that I have are (none of them are muted in
alsamixer): # amixer
