I should have added, start jackdbus with jack_control rather than using 
jackd. Make sure jackd is not already running. jackdbus comes with 
jackd2. If you have already run jackd from command line, then jack_control 
start will start it with the same command line. Changing the backend may 
take more than one line using jack_control... Jack_control has no man page 
and --help doesn't work either  :P   Just type jack_control with no 
command for all the help there is. If jack is started as jackdbus then if 
pulse has module-jackdbus-detect running, it will connect automatically. 
Otherwise you will have to load module-jack-sink and/or 
module-jack-source after both pulse and jackd are running. (if you are 
used to qjackctl, it talks to jackdbus by default)
