Since meson 0.59.0, a feature object has an `allowed()`
method which returns true when the feature is set to
'enabled' or 'auto'.
Utilize that instead of the previously used
not feature.disabled()
Most feature checks already use #ifdef, and do not care about
the value of the macro. Convert all feature checks to do that,
and simplify the meson build scripts by replacing
if cond
cdata.set('X', 1)
endif
with
cdata.set('X', cond)
For kernels compiled with CONFIG_SND_VERBOSE_PROCFS=n, the pcmXX
/proc/asound entries do not exist. In that case, the "device busy"
check cannot be done, but we should still check existence of PCM devices
correctly.
Count the number of PCM devices from /dev/snd, which should work also
without /proc/asound or /sysfs/class/sound.
Alsa device acp probe results to missing profiles if some PCM devices
are busy. Currently, we retry based on a timeout and give up after some
retries. However, exposing cards with missing profiles is never
useful.
Never expose cards if some PCM devices are busy. Instead, retry adding
device on inotify fd close events, which arrive when some process has
closed a PCM device.
When probing for devices in alsa-udev, check via /proc to avoid inotify
busy loop.
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).
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.)
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).

Enable SBC-XQ codec for the JBL Endurance RUN BT headset. The codec worked well
with pulseaudio and works equally well with pipewire.

udev/kernel sometimes give "Video Capture N" as ID_V4L_PRODUCT, which is
bogus as a device product name. The ID_MODEL* field seem to always have
a sensible product name.
Get device.product.name always from ID_MODEL*, and use ID_V4L_PRODUCT
only as the last fallback.
There is a race condition on udev permission changes (e.g. switching
VTs), when pipewire from one user closes devices, and the other process
from second user tries to open them. The close/open are not ordered, so
opening a device may fail in alsa-acp-device.c resulting to missing
devices/profiles.
Address this by trying to open devices already in alsa-udev.c. If some
devices are busy, do not emit the device info yet, but retry after a
timeout. If it still fails, go ahead emitting the device, even if some
profiles may be missing. The retry with delay should be enough to solve
the race almost always.
So that we can catch the SOUND_INITIALIZED update between enumerating
devices and starting the monitor.This fixes a races in detecting devices.
Thanks to Matthias Fend for finding this.
Fixes#2046
Devices may appear before or after their adapter does on BlueZ DBus
interface.
When an adapter appears, search the device list, and associated its
devices with it.
All exposed bluez devices should have an adapter specified at all times.
Adapter-less devices appear in some race conditions in BlueZ interface.
Require device has non-null adapter, in all cases before adding any
profiles (which exposes the device), and reject BlueZ profile connection
attempts in that state.
If an adapter gets removed by BlueZ, remove also all its devices, so
that device->adapter pointers stay valid.
Currently, the code allocates
sizeof(header) * sizeof(item) * n_items
bytes instead of the more appropriate
sizeof(header) + sizeof(item) * n_items
Fix that by simply changing the first multiplication to addition, and
furthermore, use a flexible array member instead of a zero-sized array.
Found by clang-tidy.
Since 01c6fd0a88 the
minimum required meson version is 0.59.0, and since
meson 0.58.0, `get_variable()` on a dependency object
accepts a positional argument. The "type" of variable
(internal, pkgconfig, etc.) in that case does not need
to be specified explicitly.
Parse the quantum_limit parameters and use this to scale the buffers so
that they can contain the maximum allowed samples instead of the
hardcoded 8192 value.
See #1931
Ignore latency params on the monitor ports of merger. They interfere
with the latency reporting set by the adapter.
The adapter will set the latency param from the follower on port 0 in
the converter, so pass this on to the merger as the latency and ignore
all other updates.
Fixes a case where the latency of a sink would become 0 when a monitor
port was recorded from.
We take half of the current quantum as the period size for batch
devices. Limit this to the default quantum to ensure we don't end up
with too much headroom.
