Hey, I have some success to report !!!!

> I record regularly (and play back) using JACKD, Audacity and a UCA202. I'm

Okay, this is a start. I tried it and it sort of works. Problem is
that on playback I get motorboat sound. Not what we want. I also get a
bunch of dbus errors while jack is trying to start.

So, decided to give it one last try :)

I have pulse running, etc. From a command line:

pasuspender -- jackd -d alsa -d hw:1

Start up audacity ... and it works! Using audacity setting Overdub On
I get the background playing out of the usb headphone jack. And
recording seems to be fine. Just spoke some stuff
into the mic, but that seems to work. I'll try my sax later.

I have no idea why the qjackctl is barfing. Versions?

Does this make a difference? I have jack running now at 48000 and
audacity at 44100 and it sounds fine.

So, some progress on a cold winter's day. Wonderful.
