This way, Pulseaudio clients, i.e. your browser, can use your audio
device via Pulseaudio while JACK is not running and Pulseaudio will
access the device directly, but when JACK is started, Pulsesaudio will
be routed to JACK. Normally, the even an already playing audio stream
switches seamlessly from the Pulseaudio audio sink for the device to the
new Pulseaudio JACK sink when JAKC is started.
Radhat/Fedora has a project named pipewire being developed to serve a
purpose similar to PulseAudio, except for both sound and video. I believe
the intend to bundle it in Fedora 33. I believe it intends to be less um,
cumbersome, than Pulse at working with Jack. https://pipewire.org/

be stripped down version of Cadecne coming hopefully at
the end of this year. I don't know whether the JACK / Pulseaudio setup
part will remain the same.
b) You *can* use Cadence, just be aware that the Pulseaudio config it
creates and uses may not be the same as when you run Pulseaudio by other
means.
The author of Cadence itself does recommend not
using it anymore and
there is a stripped down replacement in the pipeline.
That's sad. I tried
various ways to get JACK and PulseAudio to cooperate
with each other, and was only able to get it set up using Cadence. because,
once configured, you just start JACK (jackdbus) via your
preferred method (jack_control, qjackctl, jack-select, etc.) and
everything else happens automatically (i.e. Pulseaudio relinquishes
access to the audio device and the Pulseaudio-JACK bridge is set up and
it's ports are connected).
My preference is to set the audio device in JACK
and make PulseAudio use
JACK.
