"restored" describes a state but the only case we actually set this
value if we want to restore our previously saved profile. Rename a
variable to indicate this, makes it easier to understand.
Add module that switches bluez device profile to HFP/HSP if an input
stream (non-monitor, autoconnect) appears, and the current default
output device is bluez one that does not have input route.
When all input streams are gone, switch all changed profiles back.
Pending restore state is saved to session manager state files, in order
to restore it if e.g. devices get disconnected. This usually is not
currently necessary since the bluez5 plugin prefers to connect to A2DP
over HFP, but might matter in future with backchannel-enabled A2DP
codecs.
This test needs an environment set up to load everything correctly,
running it directly results in a segfault. Let's make sure we assert on
a NULL loop to make this look slightly more planned.
Add a new client-node port_set_mix_info event. bump the interface
version to 4 and the event version to 1.
The event is used to send information about the peer object to the
port mixer. This can be used to track what buffers belong to what
peer.
Reevaluate the graph again after we potentially suspend because of a
rate change because links might become unprepared and need to be
prepared again before the node becomes active.
We call setup_alsa_ucm_endpoint() before the
setup_alsa_fallback_endpoint(), but this function always returns
-ENOTSUP. Add a FIXME comment to make this more obvious.
spa_strstartswith() is more immediately understandable.

Applied to the tree except for alsa/acp/compat.h because it looks like
that header is still mostly as-is from PA.
Add a default.clock.allowed-rates property that lists the possible
rates for the graph.
Add node.rate and node.lock-rate properties to suggest a graph rate
and lock the rate.
Collect the largest clock rate from the nodes and if it is allowed,
try to configure it as the graph rate. Only switch rates when the
driver is IDLE or suspended or when we force a rate.
No alternative samplerates are specified because we first need to
work around a common driver bug (cards with 1 cristal need the same
rate for capture as playback) for this to work.
Rework the quantum and max_quantum handling. Work directly with the
latency fractions and calculate the final quantum size until we know
the samplerate.
The graph will not switch quantums when there is an active node
with the node.lock-quantum property set to true.
It can be used to stop certain jack clients from crashing when the
quantum changes.
Hard rate changes (the default now) makes the graph suspend so that the
driver reopens the device with the new sample rate if possible. This
causes a glitch.
Soft rate changes works as before and just changes the clock rate of
the position area, which makes everything resample things to the new
rate without a glitch.
Sample rate changes can currently still only be triggered by
configuring the settings metadata clock.force-rate
We don't need to follow nodes that we already visited or that are
inactive so skip them early.
Always try to prepare the link otherwise, not only for passive links
because non-passive links might also be paused because of a suspended
driver.
We only ever want to prepare a link between active nodes so add the
check in the _prepare() functions instead. This also makes it skip
the prepare step for inactive nodes when recalculating the graph.
This adds a new top-level documentation entry for pipewire-media-session
with a list of modules (currently only one). Similar setup to the
pipewire modules, it allows us to document all modules in-place.
