When sink is follower, and no data to write is available, it should not
schedule a timeout, but wait for the driver to wake it up again.
Fixes process ending up busylooping in data thread as follower, under
some conditions.
Also, clean up the code to be more clear about timeout logic. Just loop
directly instead of setting timeout 1, if we need to just flush more
immediately.
When acting as SCO AG / A2DP sink, the remote end should decide when to
close the connection. This does not work currently properly, because
stopping sources/sinks releases the transport, which causes it to go
idle, and which then destroys dynamic nodes. The sources/sinks should
not cause the transport to be released.
Implement keepalive flag for spa_bt_transport, such that
spa_bt_transport_release does not actually release the transport when
the refcount reaches zero. Set the flag for dynamic nodes when the
transport becomes pending (remote end connects) and unset the flag when
idle (remote end disconnected, or dynamic node removed).
Add a node.force-quantum and node.force-rate property. When no global
quantum or rate is enforce with settings, the last updated node property
is used as the quantum.
Make jack use the force-quantum property when set_buffersize is used to
make sure that the quantum is not just a suggestion but a hard forced
one. This makes it possible for ardour or other jack apps to raise the
quantum above the max-quantum but also ensure that it will not change
by any other application (unless other jack apps).
Fixes#2079
Using a probe connection to determine adapter msbc capability causes
problems on some adapters (ff8c3d2, 84bc0490a5, 717004334b,
pipewire#2030) and seems to be a bad idea.
Go back to probing for transparent msbc transport capability via HCI
commands. bluetooth/hci.h may be deprecated later, but for now it's
better to go back to using it. (In practice, adapters not supporting
esco appear to be fairly rare; kernel commit in 2013 refers to "older
devices", so if we can't use HCI, assume the adapter supports the
necessary modes.)
For now, put a limit on the amount of items we can send and receive
over the native protocol. A more complex way of allocating and freeing
can be implemented later when we really need to raise the limits.
Fixes#2070
pipewire will allocate buffers aligned to the max alignment required for
the CPU. Take this into account and don't expect larger alignment.
Fixes a warning in mixer-dsp when the CPU max alignment is 16 but the
plugin requires 32 bytes alignment for the AVX2 path (that would never
be chosen on the CPU).
See #2074
Enable SBC-XQ codec for the JBL Endurance RUN BT headset. The codec worked well
with pulseaudio and works equally well with pipewire.

This should catch any potential issues with conflicting options, missing
libraries, etc.
We need to disable aptx and roc because Fedora doesn't ship those
libraries, and we disable libcamera because it's a moving target and
shouldn't hold up the pipeline.
We must use the serial for generating the uuid.
We use the serial for the port_id and jack_port_uuid_generate() can
be used to turn that into a uuid. So all mappings to and from
uuid need to be with serials.
Do pattern matching on object properties to also allow lookups on
type, object.path, object.serial and <type>.name.

pw-dump alsa_card.usb-BEHRINGER_UMC404HD_192k-00
pw-dump alsa_input*
pw-dump Node
When a node that requires a driver is moved to a driver, collect all
linked nodes and move them to the driver as well.
This fixes the case where a single jack node (zita-n2j) is linked to
paplay. The zita-n2j node is moved to the dummy driver but paplay is not
and so nothing happens before this patch.
