Search for "pulseaudio system mode". This page is a good start:

https://www.freedesktop.org/wiki/Software/PulseAudio/Documentation/User/SystemWide/

I got PulseAudio running on an embedded system using system mode 
generally following the instructions on that page. It works, but it will 
complain a lot in the logs about running as root.

You also need to disable all the different ways PA gets automatically 
spawned in user mode (at least under systemd that is quite a pain: you 
have the autospawn feature - /etc/pulse/client.conf and 
/etc/pulse/client.conf.d/00-disable-autospawn.conf, the systemd per-user 
units and possibly some other ways I haven't figured out - I still get a 
spurious non-system mode PA daemon spawned sometimes).

You also (usually) need to have PULSE_RUNTIME_PATH=/var/run/pulse 
environment set for clients.
