Most likely something like

<decoder program> | aplay -f S16_LE -c 2 -r 44100

will do the job if you have an ALSA output device and alsa-utils (i.e. 
aplay). Depending on how the decoder deals with endianism you may need 
to use the S16_BE format. It's been a long time since I dealt with the 
example decoder so I can't remember the exact format it outputs.
