  Well, PCM is the usual "audio out" device, so that could have been part of
the problem.  If you exit and re-enter aumix, do the new settings "stick"?  
(We want to make sure nothing else is messing with them.)

  If the mixer levels are okay, try this

	cat /usr/lib/python2.2/test/audiotest.au > /dev/audio

or this

	cat /usr/lib/python1.5/test/audiotest.au > /dev/audio

Be warned that that audio clip can sound rather loud and/or bad, so be
prepared for a bad noise.  (I say to use those clips just because one or the
other or both are present on most Red Hat systems.)

  If that works, then the problem is likely in a higher-level sound
subsystem (like KDE's artsd, or GNOME's esd).  If that does not work, the
problem is likely in the kernel-level sound subsystem.
