What do the pulseaudio hooks do? If you suspend the jack sink during
system suspension and then resume it afterwards, I think it's a
reasonable expectation that the connections would be restored as they
were originally. Currently the jack code doesn't implement any such
logic... I'll file a bug.

For recreating the connection yourself, use the jack tools. The
pulseaudio tools, such as pactl, don't know anything about jack.
