Hi. I'm posting this to complete the story for the archives.
My problem went away after I restarted. I guess that would have been
a reasonable thing to try first.
The updates I installed via the Ubuntu update manager required a
restart. Maybe I failed to select real-time mode at the boot menu. I
should learn how to make real-time mode the default in that menu.
Sorry for the noise. Thanks for your help.

Hi.
I have been using Jack, ALSA, and Ardour for some time without
problems. A few minutes ago my Ubuntu update manager prompted me to
update packages. I noticed that several of them were related to ALSA.
I installed them and restarted (I didn't pay attention to what they
were).
Now Jack will not start. The failure message is pasted at the end of
my mail here. I don't think I made any other change to the
configuration.
Is anyone else having trouble with Jack after an Ubuntu ALSA update?
It was working well two days ago.
I'm using Ubuntu Studio 64bit 9.10, ALSA 1.0.20, and a Beringher
UCA202 USB soundcard.
Thanks for your help.
