Currently, when using filter nodes such as echo-cancel or filer-chain, the
ports format of the virtual stream node might not always match the format of its
associated virtual device node. This can happen if the virtual stream node is
linked with a real device node configured with many channels, such as surround
profile. In that case, the channel configuration is not forwarded to the virtual
device node, making the application not being aware of a surround setup.
This change listens for port format changes in the virtual stream nodes, and
reconfigures the virtual device node ports everytime the virtual stream node's
port format changes.
This behavior is experimental and optional, so it is disabled by default.
The 'set-volume' and 'set-mute' commands have a new --pid flag to allow changing
the volume or mute for all client nodes that are created by a specific process.
This allows scripts to declare when they have finished their loading,
so we can now also know when wireplumber is done loading and ready to
handle clients

In Lua, `0` is a truthy value, which means `not 0` is `false`. Compare
the resulting value from bitwise AND with 0 instead of checking it with
`if not` to ensure correctness.
This script, base on PipeWire module fallback-sink will create a fallback
sink node if there's no other sink available except the endpoints created
by WirePlumber.
Filter-like streams (e.g. output stream from filter-chain) should not
start following default sink, as usually the user intends their routing
to remain static, and not change unless explicitly requested.
Pulseaudio has special handling for streams associated with filter
sinks/sources, and does not make such streams follow default.
Use presence of node.link-group to determine which streams are
associated with filter sinks/sources, and don't make them to follow
default.
Previously, pw_init calls setlocale(), but this will change in future.
Setting the locale should be done by the main application, and is needed
in wireplumber for e.g. for translated UI elements.
Set the locale in main() for wireplumber daemon and tools, to have the
locale set also with the new pw_init behavior.
Set also LC_NUMERIC to C, to match old pw_init behavior.
Some devices (Mostly USB devices) have a generic pcm name (USB Audio)
that is quite useless. Filter this out and fall back to the device nick
in that case.
Since nodes may have a target specified in their props, the logic in
cleanupTargetNodeMetadata does not work correctly.
Instead, emulate what Pulseaudio does: if we see a reconnectable node
with target defined by node props, but not by metadata, which is linked
to the default sink, then make the stream follow the default from that
point on.
Setting node target by id is not safe due to id reuse, and so
target.object which specifies the target by its object.serial was
introduced, and is used e.g. by pipewire-pulse.
Use target.object specifications in policy-node if they are present.
This avoids using device.nick, which is the card name, on all nodes
of a card. Useful on UCM, where analog, hdmi, etc are all exposed
as nodes on a single profile.
Connecting dont-reconnect nodes that have a defined target to fallback
probably does not make sense.
They will be linked to a target that the client likely did not intend,
and the link will not be changed later on.
In Pulseaudio, if the defined target is not found, streams are not
connected to the fallback but instead fail. This happens also with
streams that don't have DONT_MOVE specified.
Pipewire-media-session also did not link dont-reconnect streams with a
defined target to the fallbacks.
Dont-reconnect streams should not be moved to a new target, even though
other streams would move.
Pulseaudio DONT_MOVE works like this, and also pipewire-media-session
worked like this.
When device nodes go away, we should remove links and peer_id references
concerning them, so that we don't leave behind stale links and stale id
entries in the peer_id tables.
Also fix bug in si_flags[out_id] handling in unhandleLinkable.
Policies need to know if there are session items that are pending
activation. Linkables are not activated in the same order as nodes
appear, which causes problems for e.g. resolving target nodes, if some
of the linkables are pending.
Register linkables in create-items before they are activated. When
activation completes, remove those that did not activate successfully.
Policies can filter out inactive items by tracking active-features
flags.
If there are existing linkables that are not ready, suspend policy-node
processing, and continue it only after all linkables are ready.
This makes the configuration more consistent. The storing of the default routes
logic needs to be implemented eventually in a C module-default-routes, similar
to module-default-profile.
Persistent profiles will never change. This can be useful if we want to keep
a specific device profile even if a new one with higher priority becomes
available. For example, keep the 'off' profile instead of switching to best
profile when monitor screens is resumed.
See #138
You can now override:
* Whether to store/restore properties like volume
* Whether to store/restore the target.node
* Things like media.name/application.name/etc which affect which
entry is going to be used in the state file

If a stream audio node does not have the 'media.role' property set, the policy
will asign the 'Default' media role name to it. In addition to this, if the
'Default' endpoint can not be found, the policy will link the stream audio node
with the lowest priority endpoint.
Video nodes will always be handled by policy-node.lua, and they will never be
handled by policy-endpoint-client.lua
This allows users to assign a particular endpoint for streams that don't have
the 'media.role' property set.
Only the configured headset profile needs to be persistent, the switched
status and saved profile should not persist over wireplumber restart.
When devices appear initially, they should not appear as switched,
but recheck switch status.
Monitor whether streams are running or suspended. When they are
suspended, switch to normal mode.
This is required e.g. for programs such as Teams, which keep recording
streams open but inactive for their whole runtime.
Profile restore also needs to be done with a timeout, to avoid switching
rapidly when streams are moved between sources.
Use Lua tables properly as maps.
