Hi. I have seen in bug threads in several distros where that line is commented out as a solution. I also don't think the systemd module is needed either. So I added the below to the pulseaudio.deb2sce startup script:
grep "^load-module module-console-kit" /etc/pulse/default.pa && \
sed -i '/load-module module-console-kit/s/^/#/' /etc/pulse/default.pa
grep "^load-module module-systemd-login" /etc/pulse/default.pa && \
sed -i '/load-module module-systemd-login/s/^/#/' /etc/pulse/default.pa
Works on my setup, please re-import pulseaudio or any SCEs that will be loaded that contains the pulseaudio package and test.
