Description

New point version.

I suggest holding for a few days, although this one appears to have an important bugfix:

  - An off-by-one error was fixed in the audio resampler that could
    cause distortion when downsampling.

0.3.38

# PipeWire 0.3.38 (2021-09-30)

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

## Highlights
  - Topic based logging was added to improve debugging.
  - An off-by-one error was fixed in the audio resampler that could
    cause distortion when downsampling.
  - Various bluetooth compatibility improvements.
  - More fixes and improvements.

## PipeWire
  - module-pulse-tunnel now has better default latency to make it work
    better in more cases. There is also an option to configure the
    desired latency.
  - pw-cli now has readline support.
  - Topic based logging was added. Log lines can now be filtered by
    topic using wildcards. This should improve debugging.
  - The systemd service files should now have better descriptions.
  - Fix a crash in module-zeroconf-discover when unloading.
  - Fix a crash in filter-chain when using unaligned memory.

## ALSA
  - Sync the udev rules and profiles with pulseaudio.
  - Fix a memory leak.

## SPA plugins
  - An off-by-one error was fixed in the resampler that could cause
    distortion when downsampling. (#1646)

## Bluetooth
  - Avoid probing the native backend because it might block for DBus
    activation. This fixes some long startup times.
  - Fix the kernel version check, 5.14.x kernels should also support
    mSBC.
  - Fix FastStream microphone support in more cases.
  - Add workaround for Intel AX200.
  - SCO sink should now also work in follower mode.

## PulseAudio server
  - Make the service file require a session manager.

0.3.39

## Highlights
  - media-session is now moved into a separate module to speed up its
    deprecation in favour of WirePlumber.
  - There is now an LD_PRELOAD v4l2 emulation library to run some existing
    v4l2 applications on top of PipeWire.
  - Filter-chains should now flush out remaining samples when paused. There
    is now also the option to let a filter-chain drain so that long filters
    such as reverbs can fade out properly.
  - Stability and compatibility improvements in JACK apps.
  - Better Bluetooth compatibility with more devices.
  - libcamera plugin improvements.
  - Many bugfixes and improvements all over the map.


## PipeWire
  - Fix compilation on ARM.
  - Log topics are added to most modules.
  - Documentation updates. Many improvements to the layout. Reorganisation
    of the modules and groups.
  - Share a work queue for all links and nodes. This removes the need for
    a separate eventfd per link and per node.
  - Catch errors in the map implementation.
  - Add option to compile without dbus support.
  - Fix biquad frequency. It was using the wrong sample rate.
  - Fix a potential crash when destroying nodes, in some cases the node
    would not be deactivated properly.
  - Add some more helpers for dealing with properties and their values.
  - Implement flush and reset on virtual sinks/sources.
  - Make it possible to let virtual sinks/filter-chains run and drain
    after being idle.
  - Fix a bug where the quantum could exceed the maximum because it was
    scaled with the sample rate.
  - Fix channel_map parsing in module-zeroconf-discover so that the remote
    channel map is used.
  - pw-stream errors emitted on the proxy are reported but not fatal
    any more. They are usually used by the session manager to signal status
    to the client but otherwise does not really cause an error on the
    client.
  - Links now also store the output and input node id in the global
    properties so that applications can parse and use them regardless of
    how the link was made. (#1723)
  - pw-stream and pw-filter now have an event to notify commands.
  - The echo-cancel module can now operate on larger quantums.
  - pw-cat now uses the right metadata to find the default devices in
    --list-targets.

## media-session
  - Don't try to remix unpositioned streams when linking. This ensures
    that linking to Pro-Audio nodes does not remix the stream channels
    but links them as they are, one by one.
  - media-session is now moved to a separate module to accelerate its
    deprecation in favour of WirePlumber.

## SPA
  - Many libcamera improvements, handle MemFd buffers, handle errors
    gracefully.
  - Small improvements to make interface fall-backs easier to implement.
  - Add support to enable flush-to-zero and denormals-are-zero to avoid
    high CPU usage when dealing with denormals.
  - AUX13 channels are no longer reported as AUX12. (#1727)
  - Devices with more than 32 channels in Pro-Audio mode now only
    uses AUX channels.
  - Improve windowing function of the resampler to reduce aliasing and
    improve the quality.

## JACK
  - Port connect callbacks will not only be emitted after the port
    has negotiated buffers, which improves compatibility with
    applications that try to use the port right after the callback
    (jack_midi_latency_test).
  - Fix crash when midi ports were removed and being monitored, like
    in Ardour.

## pulse-server
  - The pulse tunnel will now use the specified format/rate/channels.
  - Improve lookup of default source and fall back to the monitors when
    no sources are available.
  - Mark some nodes as network nodes so that we can set the NETWORK flag
    correctly.

## GStreamer
  - The GStreamer element not releases the buffers in the stream again in
    all cases so that they can be reused by other streams.

## v4l2
  - Add a v4l2 LD_PRELOAD library to emulate v4l2 system calls on top of
    PipeWire. This is tested with firefox and GStreamer and is known to
    not work with Chrome.

## Bluetooth
  - AAC compatibility improvements.
  - Disable hardware volume for "Tribit MAXSound Plus" and
    "SoundCore mini".
  - Add quirk to disable faststream. Disable faststream on "FiiO BTR3".
  - Add a dummy AVRCP player to improve compatibility with some devices.
