SiLink activation might be delayed indefinitely under some error
conditions. Currently, policy-node schedules a rescan when it sees a
non-activated link on a stream to be moved, which produces busy loop if
the si-link doesn't activate.
Instead of rescheduling on non-active si-links, just remove and emit a
warning. The si-link then gets removed once it gets activated.
Reproducer:
1. Play audio from Rhythmbox and pause.
2. Switch default output with pactl between two different outputs
3. Links from the paused stream stay at "init"
Unlike the rest of subcommands, The ID for the clear-default subcommand must be
a setting ID, not a pipewire Object ID. This means we cannot use the parse_id()
and translate_id() helper functions because the setting ID 0 is acceptable, and
the @DEFAULT_AUDIO_SINK@, @DEFAULT_AUDIO_SOURCE@ and @DEFAULT_VIDEO_SOURCE@
strings are not acceptable.
The move to the WpDbus API dropped the "state" property from the plugin,
but left the property enum and use of it in alsa.lua. Remove the enum and
port over the code in alsa.lua.
If a route specifies a set of profiles, it should not be used if the
profile is not in that list.
In findBest/SavedRoute, exclude routes that don't match the active
profile.
Currently in the SPA devices, the device id is different for different
profiles so this condition does not occur, but in general this might not
be so.
It's safer to have the default volume value at significant attenuation,
to mitigate situations where the output is at high gain.
Use linear scale 0.4^3 (-24 dB), which puts Pulseaudio volume sliders at
40%, as a better starting value than 0.4 (-8 dB / 74%). E.g. for many
Bluetooth headphones, the volume at 74% is still uncomfortably high, and
a lower value is better.
This causes a crash when running in a VM because the code tries to
execute lua's "type()" and ends up executing the local string variable...
Fixes: #303
Currently v4l2 nodes will get higher priority than libcamera ones.
The default can be changed, of course, with wpctl.
Things are still not great if a camera is enumerated by both monitors.
The first node to be linked will grab the device and the second one
from the other subsystem will fail to negotiate.
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.
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.
