PipeWire 0.3.24

This is a bugfix release that is API and ABI compatible
with previous 0.3.x releases.

- Highlights
  - Many JACK midi improvements and device support.
  - Fixes in gnome-control-center default sink/source handling.
  - Many small performance improvements in alsa device handling
    and latency. There should also be less cracks/pops and xruns
    now.
  - Fixes for gnome-control-center default sink/source handling.
  - More bluetooth compatibility improvements.


- PipeWire improvements
  - Implement simple upmixing.
  - Disable the resampler when not used. This improves latency
    and CPU usage.
  - Handle max-quantum on devices and try to not make the quantum
    larger than the device buffer size.
  - Improvements to how nodes and links are activated. It should
    now result in less xruns and cracks/pops.
  - meson uses the feature options everywhere now.
  - Handle volume remap in the channelmixer. This fixes the channels
    on multichannel devices.
  - Try to escape invalid JSON string characters.
  - Keep better track of changed parameters in audioconvert.
  - Improve config files, make arrays where needed.
  - Respect NO_COLOR where possible
  - Support in-place config file parsing to avoid allocations and
    improve startup performance.
  - There is now a config option to enable non-power-of-two quantums.
  - Preliminary support for upmixing and generating LFE channels.

- Session-manager
  - Default nodes are not stored as JSON in the metadata. This
    is more readable and introspectable.
  - More default-nodes and default-routes improvements. Port
    switching should work better now.
  - Wait until all devices are scanned before linking clients.
  - Fixes some crashes.
  - Sinks (monitors) can now be set as default sources.

- Device support
  - Fix startup timers for alsa devices.
  - Improve timers in alsa when quantum changes. It should cause
    less xruns and cracks.
  - Fix UCM setup of capture devices.
  - Only disable IRQ in alsa when not batch. For batch devices the
    hw pointers are updated each IRQ so we need to keep them enabled.
    This massively improves latency on USB batch devices to the same
    level as JACK (with small enough period size).

- Bluetooth
  - Improvements to profile switches.
  - Improvements to volume handling.
  - Fixes for A2DP sources
  - Add support for battery status when available.
  - Many other small improvements.

- PulseAudio server
  - Handle NULL in set_default_sink/source to clear the default.
  - Implement a workaround for gnome-control-center when setting
    the default sink/source. It also sets the target in
    stream-restore to the new default. This fixes moving streams
    in gnome-control-center.
  - Fix some races by replying to some requests after the operation
    completed.
  - Prefer formats of the extended format API.
  - Create a pid file on startup to improve compatibility with apps
    that look for it.
  - Capture streams can now be moved to monitors with pavucontrol.
  - Fixes for crashes.

- JACK
  - jack clients can now connect to the 'default' server.
  - Move midi ports back to the midi client.
  - Only mark midi hardware ports as terminal/physical.
  - Use the same midi names as a2jmidid.
  - match system ports in get_ports.
  - Improve compatibility with some apps that require a
    fixed latency.
  - Beginnings of the libjackserver implementation.

Replying to xry111:

Thank you for the heads up on this, I made sure to test it and it'll be in the commit :)
