[u-u] Audio diagnostic software

[David Gilbert]

On winblows, there is a demoware series of audio applications that give 
you many more "audio devices" that are virtual in one way or another.

One of the things on offer there is "virtual audio cable" ... a device 
for windows that has an audio in and audio out device that they 
connect.  This allows you to to connect an application's "out" to 
audacity's "in" and so on.

Another is a virtual mixer.  The various versions of the mixer add some 
number of hardware and software "in" and some number of hardware and 
software "out" ... included, also, is 4-track recorder/player.

In terms of diagnostics, this can give you visibility to the difference 
between hardware and software problems.
