After we set the format, probe if we can do EXPBUF and enable/disable
the ALLOC_BUFFERS flag on the port.
This should gracefully handle the case where EXPBUF is not available.
Fixes#3821
When we try to alloc buffers but EXPBUF is not supported, make sure to
clear the alloc_buffers flag so that the caller can try again with
allocated buffers instead.
See #3821
Reduce fallback delay values used when BT device doesn't provide the
information itself.
It may be better to have audio late than early, so use values that are
probably close to or below the delays of majority of headsets.
Don't include the quantum in latency: the latency relative to graph
cycle start doesn't depend on the quantum. Instead, the audio packet
size determines it.
Enable the /Internal media class hack also for SCO.
Session manager can use this to adjust SCO sink/source media.class when
it is going to emit front-end nodes hiding the hardware ones.
The rfcomm list may contain various AG & HF ones, so the profile must be
checked everywhere they are looked up.
Fix the rfcomm lookups everywhere to do it.
Fixes Pipewire<->Pipewire HFP connections, and sending HFP HF commands
to HSP or AG.
Add registry generation checks to pw_context methods that find globals,
(pw_context_find_global, pw_context_for_each_global), so that they are
made everywhere where a client acquires globals.
In addition to previously covered registry bind/destroy, this also
covers link creation (port/node ids) and metadata (subject ids).
If the manager gave us a different channel count than we had by
default or configured, assume everything is AUX channels.
Also handle the case where the manager is sending more than our
MAX_CHANNELS channels.
Use the sess.latency.msec also for the sender and use it to control the
NODE_LATENCY. Make it a float to be in line with the other time values.
Set is to a default of ptime, which was what it used to be.
This makes it possible to set the ptime to a smaller value than the
sess.latency.msec so that we send out multiple packets per quantum.
This will result in some bursty output for now but with a timer that can
be improved later.
Update the docs a little, mention the new rtp.ptime and rtp.frametime.
HFP 1.9 adds LC3 as a possible codec in addition to CVSD & mSBC.
E.g. Pixel Buds Pro latest firmware supports it.
Add the RFCOMM side and codec selection for it.
Move some of the tracking code for the DLL to where it is used.
Add resync.ms (default 10) option at which we give up rate adjusting
and instead do a hard resync. This results in a jump in the position
of the graph clock.
We already checked if a node is_jack when it appeared in the registry
with the client.api property, so don't check again with ALWAYS_PROCESS
when the node properties changed.
When we get a node info about our own state, we can use the active state
of the node to decide if we are running or not.
See #3794
Add a client that subscribes to the list of subscribers and make the
client watch for EnumFormat changes.
When a subscribed client sees an EnumFormat change for a sink, emit EVENT
to the client.
This will send the EVENT to pavucontrol when the supported IEC958
formats change so that it can update the gui.
Add method to update the client routes. Add an event when the client
routes changed.
Listen for route_changed events on clients that do a subscribe on the
stream-restore extension. Emit an EVENT when the routes change.
This keeps the system notifications volumes in sync between
gnome-control center and pavucontrol and probably in other tools
as well.
Fixes#3805
Add extension support to modules. This is a list of extension commands
that can be performed on the module.
Remove the custom registry of extensions and make proper modules that
implement the extensions.
This is more in line with what pulseaudio does. The advantage is that the
modules actually show up in the module list and that we can use the
module user_data to implement the extension later.
Devices may advertise other values, but not certain they will work well
in duplex configuration.
E.g. my Samsung Galaxy Buds2 Pro emits buzzing sound with 48kHz duplex
input.
Don't believe QoS values recommended by the device, which may be
suboptimal. Instead, pick the values from the BAP v1.0.1 Table 5.2.

The PAC profile UUIDs do not appear in the UUID list, but are still
useful to know before SelectProperties.
Set them ahead of time based on the visible remote endpoints.
The "default" codec is the one with fill_caps != NULL, and should be
picked if we don't know which one we are using.
Fixes showing AAC-ELD as supported when it's not, which happened because
it's ordered before the default AAC in the codec list unlike the other
"shared endpoint" codecs.
