Highlights

  • Sample rate switching should work again.
  • pw-dot can now use the output of pw-dump to render a graph.
  • Bluetooth A2DP streaming was improved that would reduce stuttering on some devices.
  • A JACK bug was fixed that would sometimes make it impossible to add more tracks in Ardour. (#1714)
  • Many bugfixes and improvements.

PipeWire

  • Fix a potential crash when NULL params were configured.
  • Add some simple functional tests to avoid some recent regressions. Improve the test framework for this as well.
  • Improvements to the poll loop to avoid some use-after-free scenarios.
  • Fix samplerate switching again.
  • setlocale is not called anymore from the pipewire library. This should be called by the application. (#2223)
  • pw_init() and pw_deinit() can now be nested and called multiple times.
  • pw_stream will now report the resampler delay in the pw_time.queued field.

modules

  • module-filter-chain now supports arbitrary many properties and will use property hints to assign them the right type.
  • The ROC modules now accept a sink/source_properties parameter.
  • The module-rt can now also be built without RT-Kit support.
  • module-echo-cancel can now use a fraction to specify the delay for more precise control.

SPA

  • The channelmixer will now do upmixing by default and will not use normalization. It will also use a simple upmixing algorithm that duplicates channels by default. A more interesting upmix method is also available (PSD) but needs to be enabled manually. (#861)
  • Add SSE optimized (de)interleave functions for 32 bits samples with and without byteswap.
  • JSON parsing of empty strings will now give an invalid number instead of 0.
  • JSON numbers are now parsed and serialized in a locale independent way so that , and . are not mixed up.
  • The resampler will now report the resample delay and queued samples as the extra delay.

tools

  • pw-cat will read more dsf files correctly and will not crash at the end.
  • pw-top now has a man page.
  • pw-dot can now use the output of pw-dump to render a graph.

bluetooth

  • Improve interactions with oFono.
  • Fix recovery with slow connections.
  • Improve frame size of AptX-ll.
  • A2DP can now use any quantum and will flush packets in smaller chunks when needed to adapt. This improves stuttering in some cases.

pulse-server

  • The server configuration can now be placed in pulse.properties section, which also makes it possible to have custom overrides.
  • Implement FIX_ flags for capture as well.
  • Small fixes and improvements in module loading.

JACK

  • Clear the last error before executing a new action or else we could end up with error from a previous action. This causes some problems in Ardour where adding a track would fail after some time. (#1714)

    I use PipeWire and EasyEffects on Fedora 35, and there are lots of sound glitches that I never would hear back in the Pulse Audio days. I hope they can fix this and the delays I get.
