[arch-general] System-Wide Pulseaudio

Hi everybody, I like to run more than one user in more than one X session at the same time and want to hear the audio from all users together. So i thought it would be nice to have a System-Wide Pulseaudio setup. I try to use this package: https://aur.archlinux.org/packages/pulseaudio-systemd/ and like shown here: http://www.freedesktop.org/wiki/Software/PulseAudio/Documentation/User/Syste... I put all users into pulse-access group after installing the pulseaudio-systemd package and reboot, but it will not work. Have anyone a hint for this situation?
