By default, PulseAudio only runs when a user does a GUI login.

I have not tried this, so this may not work. But you could try
editing /etc/pules/daemon.conf and changing "; system-instance = no"
to "system-instance = yes". You will probably have to start
pulseaudio from rc.local. (Please note that the ; at the start of
the line was removed.)

Once you have PA working correctly, you may want to play with the
network capabilities of PA. You can set up a network sink on box 1,
and a network source on box 2. You can then direct any output on box
1 to the network sink and have it play on box 2. This is one of the
things on my "to do" list.
