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.
Since 2eed279c9d wireplumber requires at least meson 0.59.0,
and the devenv feature is available since 0.58.0, the version check
before adding the devenv is no longer needed. Remove it.
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...

This allows to transparently wait until a link is PAUSED before
returning from the activation transition. This way we can also
catch negotiation/allocation errors while activating a link.
PAUSED is used instead of ACTIVE because ACTIVE depends on the
nodes being activated as well. There are cases where a link may not
activate the nodes (ex, a passive link) and the link may remain
PAUSED for a long time.

Since the string length returned by wp_spa_pod_get_data() does not always match
the size of the actual json object because it is stored in contiguous memory, we
cannot always rely on that API to get the json string data.
The new wp_spa_pod_to_string() always allocates a new string with the same
length as the json size, guaranteeing that the string returned always represents
the json object, regardless of whether it is nested or not. It is always
recommented to use wp_spa_pod_to_string() unless you know what you are doing.
The data pointer of a WpSpaJson object can be bigger than the actual WpSpaJson
size. For example, this happens when iterating an array: instead of
re-allocating the nested data into a new region of memory, the iterator uses
the same region of memory as the parent, and just sets the pointer data and size
to the correct location when creating the nested WpSpaJson object.
This patch makes sure only the data represented by the size is added into the
builder when adding a json object, fixing issues that were happening before when
adding nested objects directly from a second WpSpaJson object.
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.
