What made all the difference for me was the discovery of the
pavucontrol program, which is supposed to be the main control
gui/mixer for Pulse Audio but for some weird reason is not installed
at all by default in Ubuntu 8.04.  If you're using that distro, try
installing it via apt-get and having a look.  You can do things like
adjust the output levels of individual programs, switch them from one
soundcard to another while running, and so on.  It's like a "consumer
grade" qjackctl without the fancy routing.

Sadly not.

Another thing worth saying is that it's not useful for low-latency
recording -- it isn't a replacement for JACK in that sense at all.  It
uses big buffers and lots of latency, to avoid dropouts with standard
kernels.  However, it does report its latency accurately (in my
experience) so you can compensate for it -- you just can't do "live"
low latency work.  There's always going to be a place for JACK, with
low latency and meaningful inter-client routing.

Probably to begin with (and this is all just talk at the moment, of
course) any Pulse support in Rosegarden will be confined to playback
only.
