Playing .au sound files

[Malcolm Kay]

I'm looking for a command line utility to play .au
sound files.

The sound system seems to work. I can play .au
files successfully through kaboodle on kde but
this is rather an overkill (and I don't normally run
kde). 

Surely there is a simple utility to take a .au file
and spit it out as sound. I've looked through the ports
(and installed a number) but not yet found what I'm
looking for - or I've failed to use them correctly.
