when i first tried this, there was no change in the sound
level, because i was adjusting the wrong device, i.e.
/dev/mixer (default) instead of /dev/dsp which is where
timidity was sending its output.  once i discovered my
mistake and added "-d /dev/dsp", aumix did indeed adjust
the level as advertised.

however, when Fn/PgDn is sent a few times to lower the
level to zip, aumix is not able to make the sound
audible.  aumix -q may say:

  vol 100, 100
  synth 100, 100, P
  pcm 100, 100
  speaker 100, 100
  line 100, 100, P
  mic 100, 100, R
  cd 100, 100
  mix 100, 100, P
  igain 100, 100

but no sound emanates.  the controls seem to be in series.

any thoughts?
