I'm puzzled.  According to my synaptic package manager, the jackd showing for 
my Hardy install is 0.109.2-1ubuntu1, what does PulseAudio use?  ...since it 
is said to contain the daemon jackd as well.  Then too, 
gstreamer0.10-plugins-bad says "Depends  libjack0 (>= 0.109.2)"

~$ aptitude why jackd
i   gstreamer0.10-plugins-bad Depends  libjack0 (>= 0.109.2)
i A libjack0                  Suggests jackd (= 0.109.2-1ubuntu1)

The oil light requires as little as 3 lbs pressure to turn off so I'd think it 
would likely not!!  :)
