I've been testing the Ubuntu Studio 10.04 (not the beta, but a daily
build from shortly before the beta, so I imagine it's much the same)
because I had been hoping that, now that jack has been brought into
main, PulseAudio would be compiled with jack support so that it didn't
have to be shut down when jack started up. However, it appears that
this has not yet happened, so jack still shuts down PA when it runs.

I'm assuming that they would not be making major changes before final
release, so 10.04 will presumably still not support PA and jack
