Hi, Fernando:  I'll try installing gamix, and see what settings look 
like.  Then, if no luck spotting the obvious, I'll install meterbridge 
and qjackctl, and experiment.  When I bring up qjackctl, and click on 
connect, it shows a nice graphical display of right and left columns. 
The microphone has two choices, capture_1 and capture_2 on the left, and 
playback_1 and playback_2 on the right.  Meterbridge wants me to run a 
command that uses
$> meterbridge [-r ref-level] [-c columns] [-n jack-name] [-t type] <port>+
I'm afraid I need some guidance, here.
-r ref-level "Use ref-level as the reference level for 0db on the 
meter." doesn't provide me enough info to know what it is saying.  Help???
-c columns - I'm guessing this is one column at a time for capture_1 and 
then I rerun with capture_2?
-n jack-name "use as identifier . . . Help???
-t [type]  I'm guessing I use 'vu' here
<port>+  I'm not sure how to insert port (is this where I put capture_1 
or capture_2?
Thanks, Tom
