Well I'm currently testing this to be sure but I think my issue is
with the "priority" setting of jackd, apparently is has to be above
50?

Currently from the ubuntu repository it defaults to 0  (I
think...maybe I changed it but not sure why I would) and makes me
wonder what use it is having a value like that.  Is there any time
that a person would want a priority of zero, or anything less than the
"magical" number of 50?  Again, I don't know much about all this stuff
so I'm always trying to piece it together as I go.

Anyway, I've been trying for a long time to get a good linux audio
setup and I think I've finally done it!  Thanks to everyone who works
so hard on all this great software. :)
