I sent a long email about testing Ubuntu Studios Controls.
Since it got dumped because it was too long thanks to inserting screen
captures, I then wrote a fixed version and the subject changed creating
broken thread. I'll paraphrase (and I hope this reply is going to the
original thread. Sorry.)
Short version:
- Ubuntu Studio Controls doesn't know about ffado.
- I attempted to force things from the command line, but was unsuccessful.
In fact, I'm not sure I can even get Ubuntu Studo Controls to do nothing.
- Ubuntu Studio Controls also has a problem with retaining the selections
for bridging, etc. If you check them off, then logout/login or reboot they
are back to default (checked). The last time I logged in and started Carla,
there were 12 in/out's for the AF12 and 2 captures for the on board sound
card...
At first during my messing around I could only get the long form of the
port names to show up (i.e. 00148605c4409ac_Unknown_out,
00148605c4409ac_Unknown0_out, etc.) and not human readable names like
capture_1, etc. But, something I did is now causing the human readable
version to appear...don't what caused this and not sure if it will be there
when I boot tomorrow...

If jack is stopped, none of the settings have any effect. Bridging can
only happen if jack is running. If jack is stopped, none of the settings
in ubuntustudio-controls have effect. Pulse is running using the system
configuration. Bridging from pulse to jackd will still happen just because
the bridge auto detect is there. In -controls that jackdetection module is
removed so the bridge can be truned off.

Did you choose apply after (de)selecting them? (should the apply button be
removed?) Remember that the pulse-jack bridge is enabled by default.

session. I think the method is a bit draconian, but here's what
I do at this point.
- In Qjackctl I run the following script specified in the
Setup>Options>Execute script on Startup
jack_control stop
jack_control ds firewire dps capture none dps playback none
jack_control dps device AF12
jack_control dps rate 48000
jack_control dps nperiods 2
jack_control dps period 1024
- The Qjackctl script specified in Setup>Options>Execute script after
Startup then creates all the Calf, zita-lrx, and Pulse in/out nodes.
(Interestingly, the pulse nodes I make are used by, for example audio out
from a browser, but, I've not figured out how the system sounds get pointed
at the a Pulse device.
Also, pulse volume control still shows the alsa af12. (short of unloading
the alsa module this won't go away. And, when the alsa module is unloaded,
so goes the system sound slider in pavucontrol. And, when something like
Audacity starts, the Pulse ports the script creates get removed and
replaced. Then system sounds work.)
A side note, on this PC at least, any audio player, i.e Clementine, Payrole
Media Player have audio drop outs during play. A gstreamer issue maybe?
Apps like Internet DJ Console and Mixxx that use native JACK output work
fine.
