I'll speculate that something somewhere is confused by the presence of
two devices and either Audio1 isn't being provided correctly by pulse
(though it does create it) or requested properly by Jack (though with
only one parameter that's difficult to believe).
I now know enough about dbus to confirm this, the second interface is
not created properly for some reason.
Here's Audio0:
[liveuser@localhost ~]$ dbus-send --session --print-reply
--reply-timeout=2000 --type=method_call
--dest=org.freedesktop.ReserveDevice1.Audio0
/org/freedesktop/ReserveDevice1/Audio0
org.freedesktop.DBus.Introspectable.Introspect
method return sender=:1.119 -> dest=:1.154 reply_serial=2
string "<!DOCTYPE node PUBLIC "-//freedesktop//DTD D-BUS Object
Introspection 1.0//EN"
"http://www.freedesktop.org/standards/dbus/1.0/introspect.dtd";>

name="org.freedesktop.DBus.Introspectable"> <method

</method> </interface></node>"
Here's Audio1:
[liveuser@localhost ~]$ dbus-send --session --print-reply
--reply-timeout=2000 --type=method_call
--dest=org.freedesktop.ReserveDevice1.Audio1
/org/freedesktop/ReserveDevice1/Audio1
org.freedesktop.DBus.Introspectable.Introspect
method return sender=:1.119 -> dest=:1.155 reply_serial=2

At this point I don't think I have any doubt there's a bug in the
pulse dbus handling.
Hi,
FWIW, I tried to reproduce this last evening under Ubuntu 12.10 (which
uses PulseAudio 2.1), but it seems to create properly interfaces for the
two card scenario here. I used the "d-feet" introspect program to
verify. (Jackd2-dbus seemed to crash on startup for some reason I have
not tracked down.)
