I would sugest to use unix sockets instead of tcp to get some control
who on the remote machine can get access to your pulse-server.


logon to the remote machine and prepare the enviorment there.
local$ ssh remote
remote$ mkdir -m 700 /tmp/pulse-remote
remote$ export PULSE_SERVER=unix:/tmp/pulse-remote/native

use a separate terminal to create a remote listening socket:
local$ socat EXEC:'ssh remote "socat STDIO UNIX-LISTEN:/tmp/pulse-remote/native"' UNIX-CONNECT:$HOME/.pulse/`cat /var/lib/dbus/machine-id`-runtime/native

play some music in your remote terminal.
remote$ mplayer my-music.mp3
