Glenn Johnson:
 |Is there any way to control the sound volume level of sound files redirected 
 |to /dev/audio? Thanks.

(If I understand your question) you probably want to install one of the
"mixer" packages:

audio/xmix
audio/xmmix

They'll let you tweak the various sound card volumes graphically.

If you'd prefer a text-only method (good for scripts), there's:

/usr/sbin/mixer

which (at least) is available on R2.2.1.  For playing .au's and other
PCM-outputs, try:

mixer vol 50    to adjust the global card volume
mixer pcm 50    to be selective and just affect PCM.
