For debugging, it may be useful to disable some of the codecs. Enable
configuring this in config file, to make it more convenient for users,
who may not know how to recompile/install pipewire.
Disable automatic port configuration in acp and move the logic
to the session manager.
Implement initial port selection and restore on profile activation.
Implement route switch when unavailable
Implement port settings save.
The motivation is to have both existing and new streams that have been
created without explicit target node, to be directed to the same devices
at all times. To achieve this:
Consider what find_node returns as the "default node".
Consider streams that auto+reconnect and don't have an explicit target,
as following default. In rescan, if the default node has changed,
relink such streams to the new default.
Remove the old code that explicitly moved streams when the default.*
metadata changed, as it implements a similar thing but in a less robust
way (may fail to do what's intended, because the default device
metadata is commonly unset, or the metadata callback comes before
session_create has seen the new nodes).
Enable this feature based on "policy-node.streams-follow-default"
property. Allow setting the property also by loading the
streams-follow-default module. Enable it by default only for the
with-pulseaudio module group.
Add a new build option 'system-user-unit=dir', which can be used to
override the pkg-config default value.
By doing this, it becomes more practical to make a local unprivileged
build of the latest PipeWire:
$ meson --prefix=~/.local build
$ meson configure build -Dpipewire-alsa=false
$ meson configure build -Dsystemd-user-unit-dir=~/.config/systemd/user
$ meson configure build -Dudevrulesdir="`mktemp -d`"
$ ninja -C build install
For a local build enabling ALSA plugins is not plausible.
JACK needs a simple addition to the ~/.profile:
export LD_LIBRARY_PATH=$HOME/.local/lib/x86_64-linux-gnu/pipewire-0.3/jack
Finally, the genuine PulseAudio must be masked and local services
enabled:
systemctl --user enable pipewire.socket
systemctl --user enable pipewire-pulse.socket
systemctl --user mask pulseaudio.service
A sanity check [*] shows that nothing has leaked out of the home
directory (even though at least on my Debian 10 system PolKit still
asks for authorization during the meson build).
Not perfect, but lowers a barrier to run the development version a lot,
as that does not anymore to trash your system.

Remove -e and -d options
Manage modules in media-session.conf
Add alsa-monitor.conf that can match node/device properties with
a regex and update properties on it. All previous configuration and
more cane be done with this.
Long story short, this is something pulseaudio has since 2017 [1]. If
pipewire-pulse is aiming to be a drop-in replacement, the same behaviour
is probably expected.
I noticed that without this line I hit some issues with systemd socket
activation. In fact, it does not work properly at all. It probably has
something to do with the fact that pipewire-pulse is started for GDM
session and is somehow propagated down to my own user session.
