The codec may need to take into account endpoint preferred QoS values,
so parse this information and pass it to the codec's get_qos.
All the QoS struct values need to be set, as otherwise BlueZ may pass
uninitialized zero values over the air, which devices can reject. This
does not apply to CIG/CIS ids, which are automatically allocated by
default.
Fixes connecting to nrf5340 devkit, which requires a valid TargetLatency
value.
Commit 947ee152d3 ("bluez: check dbus service before enumerating objects")
introduced a check that would esure that GetManagedObjects()
is not called if the "org.bluez" name has no owner. This
was done to avoid auto-starting the bluez daemon.
However, this is not needed because it is possible to set on
a per-message basis whether or not the destination service
should be automatically started by the dbus daemon.
When we were using the resampler and then bypass it when the configured
rate == 1.0, we create a pop because we don't process the queued data in
the resampler anymore.
Avoid this by keeping the resampler active as soon as the rate property
is set on the audioconvert. The resampler itself will use a more
efficient copy method in that case anyway and it is expected that the
rate will change again later when we need to reactivate the resampler.
pw_stream_connect can take a very long time to finish connecting. This
process continues after snd_pcm_pipewire_prepare has released lock on
pw->main_loop and during this time the device returns EBUSY on write
attempts. This adds a significant latency to playback compared to pre-
pipewire configurations. This is a problem when using for example
Gstreamer alsasink with tight time synchronization options since
GstAudioBaseSink keeps track of internal time by counting processed
samples. Also worth noting is that alsasink calls prepare often,
for example on receiving a caps event.
With this change an existing pipewire stream will be updated rather than
destroyed and re-created when prepare is called.
By default no modem is allowed.
Property "bluez5.hfphsp-backend-native-modem" can be 'none', 'any' or the
modem device string has found in 'Device' property of
org.freedesktop.ModemManager1.Modem interface, e.g. for PinePhone
"/sys/devices/platform/soc/1c1b000.usb/usb2/2-1".
