[AG-TECH] APware running - always or just when needed

I run APware all the time with our XAP 800.  The static
filled sound can sometimes be a sign that one of the stages
of the gentner's audio-processing pipeline is either over or
under-driven (this being digital audio, the effects of this
are more perverse and unpredictable than you'd expect in an
analog system). 

APware provides you with level-meters for each stage of the
processing pipeline, so it should be a piece of cake to
check from end-to-end.  Also, check kmix on your linux/audio
box to make sure the output levels are correct and listen to
the quality of the audio output on you linux box using
headphones.  Perhaps even test your Gentner audio levels out
by playing a CD on your linux box.  There are just too many
stages to arbitrarily blame one piece of equipment.  I had
some wierdness like this early on that turned out to be
driver/audio problems with the linux box.

But regardless, I leave APware on all of the time with no
ill effects to the Gentner.
