Still, pulseaudio should not hang when rtkit cannot start. As a workaround, you might try disabling high-priority and realtime-scheduling in /etc/pulse/daemon.conf (although that will probably give you suboptimal performance). Could you please report this bug upstream at https://bugs.freedesktop.org/enter_bug.cgi ? -- Saludos, Felipe Sateler
