(but swear I didn't previously, actually seemed to work just now as...) I
don't believe you mean pavucontrol but I can see no package called pactl on
Ubuntu Studio...
pactl is a cl tool that is a part of the pulseaudio package.
examples:
pactl unload-module module-udev-detect
This will keep PA from detecting new audio IFs such as USB devices
pactl unload-module module-alsa-card
this one will keep PA from seeing any alsa device
Now PA has no choice but to see jacksink/source as default.
Now I am tracking and I want to only monitor ardour
pactl unload-module module-jackdbus-detect
will (so long as I am using jackdbus and not jackd) remove all desktop
noise without stalling any of the desktop apps because PA will create a
dummy output.
now I am finished recording and someone wants to show me a youtube vid
pactl load-module module-jackdbus-detect
and my desktop sound now works again.
http://www.ovenwerks.net/software/index.html shows the tool I use for
(un)loading jacksink/source and some other things. I am not ready to
release it yet as I wrote it for upstart which while still around....
14.04 uses it... is on it's way out the door. I need to systemdize the
commands to shut off unwanted services for low latency work.
