The bridge is active by default on qjackctl. All you need to do is to 
choose jack as the output from the pulseaudio mixer. This will route 
pulseaudio to jack.

If you've made any settings changes to qjackctl, make sure "Enable D-Bus 
interface" is on, under "Setu"p -> "Misc".
Also, jackd2 is required (installed by default).

When you start jack, you should see "PulseAudio JACK Sink" and 
"PulseAudio JACK Source" under "Connect" -> "Audio". Second step is as 
mentioned above, to set pulseaudio to use jack as it's output (and 
input, if you want to route jack audio to pulsaudio).

Not everything appears in Software Center, so you might need to install 
some things using the terminal, or use *Synaptic*.

Apparently Cadence
