I got that the first time - after selecting JACK in the I/O
preferences and restarting Audacity it was OK.

Maybe try stopping JACK, starting it and then starting Audacity again.

I've been using 44100 for all my tests - maybe that's the problem. I
also built portaudio v19 before building Audacity; that may make a
difference. From the audacity source directory created in the cvs
checkout, it's just:
then build Audacity as described.
Please report your experience on the audacity-devel list and hopefully
it can be sorted out.
