Currently, if the default node appears without ports for a short period of time,
the default nodes module will never select it immediately because it does not
listen for port changes. We want to listen for port changes to reevaluate again
the nodes that did not have ports before. This allows switching to the default
node as soon as it has ports if it did not had ports before.
7908b8d7be2a2992c57cd549054eda7ce46e4b44 ("m-lua-scripting: allow
converting GValue holding NULL objects to Lua") accidentally added a second
refcount. As a result, the objects are never freeded.
Remove the second refcount to fix this.
This check was originally added to avoid a small audio glitch when changing
default nodes while also changing the device profile (eg Gnome Sound Settings).
The check is removed because it causes issues when disabling alsa nodes. There
are plans to fix the audio glitch issue in the future with the planned
event-dispatcher architecture.
Fixes#279
There is no need to have this as an optional module, since libintl
is a hard dependency of both PipeWire and GLib. This way we can keep
things a bit simpler and faster (no string copies and plugin lookups)
Bump meson dependency to 0.59 to benefit of the libintl lookup that
is now built into meson's dependency() function.
We're only interested in notifications for user state changes, so we should
better be more specific about it when creating the systemd login monitor.
This avoids issues with sd_login_monitor_new() returning EINVAL if
systemd-machined is not running (and thus /run/systemd/machines does
not exist).
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

The load functions used to do 3 things:
- push the sandbox function on the stack
- load the file and push it as a function on the stack
- call the sandbox (or the file)
Now there are separate functions to do these 3:
- wplua_push_sandbox
- wplua_load_*
- wplua_pcall
Some nodes can omit the format/rate/channels to indicate that they can
deal with all possibilities and adapt to what they are linked to.
See pipewire#876
Some devices have different nodes for speakers and headphones. In that scenario,
this change notifies the policy to re-link all clients to the new default node
when the user plugs and unplugs the headset.
This reverts commit ad80faaa8d.
The same issue is fixed by the intermediate commit by Wim. Let's revert
this to keep the logic in-sync with policy-node.lua and media-session.
This makes sure nodes are ready before finding the default node, avoiding audio
glitch in wrong device if profile was also changed while changing the default
node (can happen with Gnome Sound Settings).
Since nodes are destroyed and recreated again when a device profile changes, the
only way to make sure device nodes are ready is to check the profile classes
structure, which tell us how many total nodes the device has, and then check
that those nodes exist for that device. A rescan is triggered whenever devices,
nodes or ports changed.
This patch also improves the logic when finding default nodes, allowing virtual
sources to be set as default sources.
Fixes#85 and #130
