Accesing sound card on remote machine

[Radek Vokál]

This is not a big issue, more a fun for me. I have another machine
standing next to me with soundcard and speakers and I would like to
control it remotly but ssh-ing on the machine and running mpg321 doesn't
give me any sound. Does anyone know the solution for this? What should I
allow on the remote machine to hear my music?
