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.
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.
