Pulseaudio sound across network

[Colin Law]

I  am trying to get pulseaudio to allow playing sound from one PC
(Ubuntu 5.10) to another (Ubuntu 14.04).  Following instructions found
in various places I have installed paprefs and pavucontrol and on the
server (the one with the speakers), in paprefs I have enabled network
access to local sound devices, allow other machines to discover local
devices, don't require authentication.  On the client I have enable
Make discoverable network devices available locally.  I believe that
now the server device should appear in client pavucontrol but it does
not.

Pulseaudio daemon is running in both machines.  No obvious errors in syslog.

Any suggestions?
