ah, you appear to know this. so you've switched to the USB device, and the
problems are gone. pretty much points to the sort of device-specific issue
that david was referring to, i think.

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:

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 <this is a test> 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.
