I haven't checked lately.  There are numerous bugs are still open about this
subject, although perhaps not for exactly what we are discussing.  And since
this type of issue isn't discussed or announced openly and pervasively it is
sometimes hard to keep up with changes/improvements.

I am currently replacing Lucid on my main machine with Natty Ubuntu Studio
and will test this however.

But David, can you explain the behavior you would expect me to experience?
Will I see Pulse Audio sources in JACK?  or simply JACK sources in Pulse
Audio?

Will this require manually adding the additional module you described?  or
is it already included?

Thank you,
