Hi Ross!
I see what's going on. They made pipewire-audio a hard Depends of
ubuntu-desktop. pipewire-audio itself is a metapackage which has a hard
Depends on pipewire-alsa. ubuntu-desktop having a hard Depends on
pipewire-audio seems wrong. Unfortunately, I have no good fix for that.
However, it does seem as though it's not removing anything critical, so
that's the good news, just the ubuntu-desktop metapackage. However, I
do wonder why they made pipewire-audio a hard Depends as opposed to a
Recommends.
Either way, what you have should still work. It looks scarier than it
is, but it's still working exactly the way I designed it to work.

Hi All,
As you may remember, one of my machines runs plain Ubuntu, has a
spare USB Audio device plugged in, and I have been testing Ubuntu
Studio on top of Gnome (ubuntustudio-installer did this for me
several releases ago).
Last night I upgraded to 23.04 and as expected, saw that Studio
Controls was removed. Running ubuntustudio-installer to install
ubuntustudio-pulseaudio-config failed. To try and understand what
might have gone wrong, I tried to install us-pulse*-config on the
command line. It (apt) was going to remove ubuntu-desktop which I
thought was a bad idea and said "no":
~$ sudo apt install ubuntustudio-pulseaudio-config

Do you want to continue? [Y/n]
I have not looked into the dependencies to see if there is a way to
untangle this. Instead, I was wondering if it was worth playing with
the pipewire setup. It is a test setup after all! Does anyone know of
any good guidance on the workflows in this set up? What would I use
to help all of the routing between pipewire, jack, and how to use
Ardour/Hydrogen/Carla etc.?
From the packages listed for removal above, I assume that wireplumber
in the answer?
I did see some discussion on LAD, but I was hoping for some blog with
easy instructions, screenshots etc. :-)
Cheers,
Ross
