Well, no matter if Audacity is recording or playing,
all I see in qjackctl, [Connect], "Audio" tab is:

== == Readable Clients/
== == Output Ports
== == - system
== ==     capture_1
== ==     capture_2

on the right, and then on the left, I see:

== == Writable Clients/
== == Input Ports
== == - system
== ==     playback_1
== ==     playback_2
== ==     playback_3
== ==     playback_4
== ==     playback_5
== ==     playback_6
== ==     playback_7
== ==     playback_8

I see don't see a mention of audacity or portaudio.
Also, does "system" refer to my M-Audio card or
the integrated audio on the motherboard?
If system does refer to my M-Audio card, I don't
see anything in the under Readable Clients/Output Ports
that distinguishes between the s/pdif input and the
ADC input.

On the other hand, when I run mhWaveEdit, as suggested by
Mr. Ovens, I do see the word "mhwe" listed both in 
the Readable Clients/Output Ports and Writable Clients/Input Ports.

At this point, I can continue to work with mhWaveEdit
as audacity appears to be problematic.

----
So running mhWaveEdit, I still cannot create any audio
files with actual sound, or see mhWaveEdit's VU meters
show any volume.
So, does "system" in the connect window of qjackctl
refer to my M-Audio card?
Thank you for your suggestions!
