Regarding the Debian documentation https://wiki.debian.org/PulseAudio
Setting "autospawn = no" in /etc/pulse/client.conf has no effect! I did also try cp /etc/pulse/client.conf ~/.config/pulse/ pulseaudio --kill You always have this process "00:00:00 /usr/bin/pulseaudio --daemonize=no" I tried to delete the configuration in ~/.config/pulse/ without no effect. When you rename /usr/bin/pulseaudio then pulseaudio cannot start but you don't have any sound in KDE! What must be done to get rid of pulseaudio and to get direct sound with ALSA? When you try to remove the package there are to much dependencies: # apt-get purge pulseaudio Paketlisten werden gelesen... Fertig Abhängigkeitsbaum wird aufgebaut.
