PipeWire 0.3.52 (2022-06-09)

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


  • Add 44.1KHz to allowed samplerates. The server can now switch by default between 48KHz and 44.1KHz.
  • Streams now allocate less resources.
  • Fix some bugs that could make the server crash.
  • Bluetooth now supports the LC3plus vendor codec.
  • Many bugfixes and improvements.


  • Add 44.1KHz to allowed samplerates.
  • Avoid setting the locale.
  • Avoid use-after-free when destroying a node from spa-node-factory.
  • Avoid using reallocarray when not available.
  • Set port alias is not otherwise set.


  • Improve filter-chain parsing and error reporting. Handle empty nodes. (#1950)
  • Handle destroy of globals and factory in most modules. (#565)
  • Add refcounts to client and resources to handle destroy of the protocol. (#565)
  • Handle global node.name in filter-chain and loopback again, use it to construct unique stream names.
  • Avoid a wrapped pw-node in the adapter. This reduces resources allocated for streams.
  • Fix a crash when module-x11-bell was unloaded. (#2392)
  • Add a new module-pipe-tunnel that can write/read data from a UNIX pipe.


  • Fix DSD playback again in pw-cat.
  • Add -n option to pw-loopback to set node names.
  • Add -P option to pw-cat to pass properties to the stream.
  • Support stdin/stdout in pw-cat. (#2387)
  • pw-dump now also dumps object removal when monitoring. (#2426)


  • Avoid duplicate param results in pw-dump for ports.
  • Avoid endless loops in audioconvert for badly behaving client. (#2359)
  • Scale max-error in alsa based on quantum and avoid logging a warning when starting.
  • Improve debug of failed format conversion. (#2383)
  • Handle offset in the audio dsp mixer inputs and clamp to the max buffer size.
  • Add option to disable locale support for JSON number conversion.
  • Add support for Astro A20 Gen2.
  • Fix some of the test sources, the flags were not set correctly.
  • Add camera location as property in libcamera and let the session manager Generate a localized description.
  • Fix some crashes due to wrong vargar types in v4l2 controls. (#2400)
  • Improve ALSA resync behaviour. (#2257)
  • Add support for Komplete Audio 6 MK2.
  • Improve loop cancel while iterating.
  • Try not to mix surround channels and AUX channels. Make card with many ports look better when not using the Pro Audio profile.
  • Vulkan filters were added.


  • Add LC3plus vendor codec.
  • Handle unsupported indicators better.
  • Ensure multiple devices on an adapter use different codecs because one endpoint can only be used by one device at a time.
  • Fix bitpool control as a follower.
  • Handle bluetooth errors better.
  • Speed up bluetooth connection by only waiting for the profiles supported by the adapter.
  • The dummy AVRCP player is disabled by default because it seems to break more devices than it fixes.


  • Add initial stream latency property so that devices can be started with a resonably accurate latency.
  • Fix ringbuffer underrun case. (#2366)
  • module-native-protocol-tcp now has a auth-anonymous option to give full access to the clients.
  • Report a node as being moved when it is still moving. This improves compatibility with pasystray.
  • Avoid overallocating message memory.
  • Don't export NETWORK nodes in zeroconf. (#2384)
  • Fix stride for TrueHD and DTSHD passthrough. (#2284)
  • Make sure we don't send too small audio fragments. Fixes capture from multiple tabs in Chrome. (#2418)
  • Rework module handling some more.
  • Use the new native module-pipe-tunnel for pipe-sink and pipe-source.
  • Implement the STREAM_MOVED message when a stream got moved. (#2407)
  • Fix a potential segfault when stopping the server and a TCP module as still loaded.


  • Add support for updating sw_params at runtime, mostly the min-avail param.
  • Capture and playback nodes are now assumed to use a different clock and will activate the adaptive resampler when linked. This assumption is removed in Pro Audio mode. This provide a better experience out of the box with most devices.


  • Fix setting properties with PIPEWIRE_PROPS again.
  • Don't use 64 bits atomic operations for sync_timeout. (#1867)
  • Cleanup in error cases was improved, avoiding some crashes. (#2394)


  • Fix pipewiresink in mode=provide. (#1980)
  • Share memory into a new buffer in pipewiresrc to avoid buffer corruption.
  • Fixes to the source and fd use.
  • It is now possible to set client properties as well. (#1573)
