    Release 0.3.14 Release

    PipeWire 0.3.14

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

    • Highlights

      • This release focuses on bugfixes and stability improvements.
      • A new experimental pulse-server module was added. This module implements the pulseaudio protocol on top of PipeWire and can be used to make flatpaks work with PipeWire. It looks like this might be a better way forward compared to the libpulse.so replacement library.
      • A2DP bluetooth was reworked. Playback should work a lot better now. Support was also added to automatically link an A2DP source to a playback device, which makes it possible to use PipeWire as a bluetooth receiver as well.
      • Improvements to the routing and volume restore features of the session manager.
    • PipeWire improvements

      • The channelmixer does not normalize volumes anymore. Volumes are only normalized for monitoring streams now.
      • Streams can actually start in the inactive state now.
      • The channelmixer can now also convert volume updates from one channel layout to another. This makes saved volumes work even when streams have different channel layouts.
      • Clients are only registered after the properties have been updated.
      • Links now have a new active state.
      • Drivers can now also specify a minimum quantum. This makes it possible for bluetooth devices to specify an optimum quantum for the given codec settings and MTU.
      • The amount of data sent over the socket was reduced by only sending the data that changed.
      • Client objects are now exposed after they uploaded their properties, which makes the new object more useful.
    • Tools improvements

      • pw-cat will now add metadata to the PipeWire streams.
    • Session manager improvements

      • Fix crashes when reading bad data in stored settings.
      • volume and routing is improved. Settings are now remembered per application or media-role.
      • The session manager remembers the last device used per stream
      • Fix a bug when moving streams where it could sometimes end up with linking a stream to multiple devices.
      • Use RTKit to set realtime priority on the data thread in the session manager. This improves performance of the pulse-server and bluetooth devices.
      • Add a new property to mark streams that want to capture from the monitor of the default sink.
      • NODE_TARGET can now also contain the node name. This avoids some lookups in the pulseaudio layer when selecting target nodes by name.
      • the -e and -d options are more usable now and can be used to add and remove modules from the default list of modules.
    • Device support

      • v4l2: add some workarounds for buggy drivers. Add Limited support for droidcam.
      • ACP: improve selection of default port and profiles.
      • ACP: add support for using the hardware mixer for more than 8 channel streams.
      • ACP: support the new port type and availability group found in PulseAudio.
      • A2DP bluetooth timings were reworked. Automatic linking of A2DP sources was added to make it possible for PipeWire to act as a bluetooth receiver. The code was reworked to allow other codecs such as APTX and LDAC in the future.
      • Try harder to recover from ALSA errors.
    • GStreamer improvements

      • Fix some crashes in the monitor that cause gnome-initial-setup to crash.
    • PulseAudio layer improvements

      • Many compatibility improvements. Improved playback in chrome. Fix a crash in firefox when the daemon is stopped.
      • Fix a leak in the formats.
      • Fix !ADJUST_LATENCY streams like paplay.
      • Make the device option in paplay work.
      • Fix volume/mute notifications, this makes plasma volume updates work again.
      • Do the conversion between PulseAudio cubic volumes and PipeWire linear volumes. Volume levels should behave now like they did with PulseAudio.
    • JACK layer improvements

      • Return an error when we run out of midi events. Some application rely on this behaviour.
    • ALSA plugin improvements

      • The ALSA plugin now also supports the node name in the playback_node and capture_node properties.
  • 0.3.13

    Release 0.3.13 Release

    PipeWire 0.3.13

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

    • PipeWire improvements

      • Add pw-reserve tool to reserve or monitor a device on DBus.
      • Install spa-resample, a tool to resample a file.
      • Install spa-acp-tool, a tool to inspect the card profile.
      • Various fixes and improvements
      • Fix a bug in pw-stream where a capture stream could run out of buffers and become silent.
      • Rework the processing loops in the adapter and stream. There is now less latency in PulseAudio and ALSA layers.
    • Session manager improvements

      • Improve the device reservation code. We now try to acquire the device using the dbus device reservation API before we probe the device. This avoids conflicts with a running PulseAudio where devices would disappear (because they were locked by the other process).
      • Don't fail on invalid input from the config files.
      • Audio devices now have the same name as what PulseAudio would assign.
    • Device support

      • v4l2: try to use the format before enumerating the size and framerate. Some drivers don't check the format and might now work better.
      • v4l2: Fall back to MMAP when EXPBUF fails. Fix MMAP access, just export the fd and the mapoffset. This should make more devices work.
      • Fix crash in ALSA Card Profile (ACP) code.
      • ACP: fix selection of default profile. Prefer any possibly available profile over 'Off'. This makes some card at least start with something.
      • Fix soft volume. After setting the volume to 0, it would stay at 0 until pushed over the max volume. This should fix various volume related issues.
    • PulseAudio layer improvements

      • Rework the buffering and latency measurements and tweak the buffer attributes. This should make browsers and media players work better. This should also improve speechd performance.
    • JACK layer improvements

      • Fix compilation against newer JACK.
  • 0.3.12

    Release 0.3.12 Release

    PipeWire 0.3.12

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

    • PipeWire improvements

      • the channelmap converter now handles unknown and strange channel layouts much better.
      • the resampler is now cleared correctly, avoiding clicks and pops at the start of sound.
      • Fixes for various crasher bugs. (paplay drain, vlc shutdown, pactl info, ...)
      • Fix a race condition in the node state changes that caused all kinds of sync and other issues (vlc, mpv, ...)
      • Improve the binary name property of applications
      • Fix the scheduling again of nodes that always need a driver such as the jack clients.
    • Session manager improvements

      • fix routing to default nodes. Sometimes nodes were not routed to the default node (bluetooth)
    • Device support

      • disable channelmap from ALSA by default. This is what PulseAudio does and thus provides better compatibility.
      • fix a bug in how the resampler was used in the ALSA source, causing distortion and errors when using low latency capture clients. (Discord, webrtc, ...)
      • Small bluetooth improvements. More work is needed for reliable bluetooth playback.
    • GStreamer plugins

      • the device provider now stops the processing loop before shutting down, which avoids crashes (gnome-initial-setup).
    • PulseAudio layer improvements

      • the buffer attributes were reworked to ensure compatibility with many more applications such as mpv and audacious.
      • the pulseaudio layer will now try hard to not hand out invalid channel maps to the application. (avoids crashes in gnome-volume-control). The channel map will now also look more like what PulseAudio does.
      • the @DEFAULT_SINK/SOURCE/MONITOR@ wildcards now work. This fixes the problem with volume keys when they are bound to scripts using pactl and the default sink/source wildcards.
      • the PIPEWIRE_LATENCY environment variable now works again
      • Fix some leaks of ports and port info. Also fix the leak of the context when the mainloop is stopped.
      • The sink/source format_info array is now filled up completely, this is actually not implemented yet in the real PulseAudio.
    • JACK layer improvements

      • jack now returns version 3.0.0 and has PipeWire in the version string so that apps can report this.
  • 0.3.11
    b0c75871 · 0.3.11 ·
    Release 0.3.11 Release

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

    • PipeWire improvements

      • Properly cleanup the mixer structures when a port is removed, this should fix client crashes related to port config changes and other random crashes.
      • Optimize the preferred formats in the audio converter. Higher quality formats with higher performance are chosen first.
      • Make sure the time reported by pw_stream is always increasing, even when the driver and clock changes.
      • There is now also a system service and socket that can be used to enable PipeWire systemwide. This is however not recommended and disabled by default.
      • Fix channelmixer 5.1 to stereo mix matrix. It was not reading the conversion matrix correctly and cause channels to be dropped. The channelmixer will now also normalize the volume, like what pulseaudio does.
      • The channelmixer will now just copy channels when no layout has been given. It has also optimized paths for this. This makes it possible for apps to request > 8 channels from the alsa plugin (ardour).
      • Port, Node and Link will now also emit an error on the resources in addition to updating the error in the info. This would make it easier to track negotiation errors in the session manager later.
      • many small fixes and cleanups.
      • Fix compatibility: + DOSBox: fix crash because of double free in pw_stream
    • Session manager improvements

      • The session manager will now try to configure the client to the channel configuration of the sink/source. It will only do this for downmixing, never for upmixing and also never when the client has the dont-remix property set. It will also renegotiate the channel layout when moving a stream to a new sink/source.
      • Configuration state is now saved in XDG_CONFIG_HOME. Previously it was saved in $HOME/.pipewire-media-session/ You can migrate the state by moving the files to $XDG_CONFIG_HOME/pipewire-media-session (or $HOME/.config/pipewire-media-session as a fallback when XDG_CONFIG_HOME is not set).
    • Device support

      • Bluetooth sources and sinks should work better now.
      • There is now also a new bluetooth backend using hsphfpd.
      • fix the ALSA UCM Off profile for alsa pcm devices
      • improve ALSA port and profile switching. The ACP device will now switch to the best port and profile when availability changes.
    • PulseAudio layer improvements

      • Implement some more callbacks. The pulse layer will now also notify applications of stream moved, started and latency changes.
      • Fix error code when an object was not found. We now return PA_ERR_NOENTITY instead of PA_ERR_INVALID.
      • Add some support for loading new null sinks. Applications such as pulseeffects use this. Note that pulseeffects does not yet work reliably but can start now.
      • Improve handling of profile and port updates, it should work much more reliable now. Apps should now also again receive volume updates from sinks/sources.
      • Fix compatibility: + openal-soft 1.20 + pavucontrol (checks PA_ERR_NOENTITY)
    • JACK layer improvements

      • improve default source and sink handling. It was not updated correctly in all cases.
      • add samplerate and period to the pw-jack wrapper to easily configure the desired samplerate and perdiod for the app.
    • ALSA plugin improvements

      • Add a mixer entry in the alsa config file.
      • Implement support for planar types, rework the processing function to make it more robust.
      • refuse to load the alsa plugin when linked against 0.2. This catches some old apps linked against 0.2 that want to use the alsa plugin.
      • Fix compatibility: + linphone (ALSA SIGFPE when _status() is called before _prepare()).
  • 0.3.10
    69be1418 · 0.3.10 ·
    Release 0.3.10

    PipeWire 0.3.10

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

    • Many improvements to the pulse layer.

      • GStreamer pulsesink element now works.
      • Fixes some segfaults.
      • Enable rtkit for client threads.
      • fixes capture of monitor stream by name
      • implement some more extensions, this makes paman work and removes some warnings.
    • Many improvements to the GStreamer elements

      • negotiation rework, avoid calling GStreamer methods from the PipeWire callbacks because they might block and cause deadlocks.
      • Add support for non-string property values.
      • improve stability after buffer and format renegotiation.
      • Rework the device provider.
      • pipewiresink can now provide a stream that can be consumed by apps like cheese.
    • Many improvements to the JACK layer:

      • Rework the buffer_size callbacks. Make sure we call the callback from a 'safe' thread and that we don't call the process callback while the application is handling the callback. This improves stability in apps like Carla when PipeWire dynamically changes the buffer size.
      • Improve compatibility with apps that call get_buffer_frames() with a 0 size (calfjackrack)
      • JACK can now create nodes that can be set as a sink/source in PulseAudio/ALSA apps (you can make an effects rack and set that as default sink for apps).
    • Added a group id property for nodes. This makes it possible to schedule nodes with the same driver even when they are otherwise not linked together. To make this work well a new flag needed to be added to nodes to signal when they are ready for processing.

      Together with the GStreamer fixes, this makes things like:

      gst-launch-1.0 -v pipewiresrc path=51 stream-properties="props,node.group=1" ! audio/x-raw ! pipewiresink stream-properties="props,node.group=1"

      work as expected with PipeWire managing the resampling to keep the clocks of the devices in sync.

      This can later also be used to force devices to be grouped together to create a JACK-like scheduling group.

    • Streams and filter now use PIPEWIRE_NODE and PIPEWIRE_LATENCY env variables as fallback.

    • ACP add per device port list. This makes UCM devices expose the right ports.

    • Fix some segfaults in ACP and UCM.

    • make pw-cat use the metadata to find default devices.

    • The media session can now save and load audio device Profiles and Routes (volumes), stream volumes and the default sink and sources.

  • 0.3.9

    Release 0.3.9

    PipeWire 0.3.9

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

    • Fix bad audio in chrome

    • Remove some errors that are not real errors.

    • Fix 100% cpu when disconnecting devices.

    • Improve pulseaudio introspection of formats

    • Fix JACK metadata handling, carla can now monitor the port it creates and insert midi.

    • Add a new permission bit (M) that is needed to be able to configure metadata on an object. Improve security of metadata some more, only allow metadata on objects that are visible to the client setting the metadata.

    • Add support for videocrop in the GStreamer elements.

    • Improve handling of the runtime directory for the server sockets. Add some reasonable fallback when XDG_RUNTIME_DIR is not set, as suggested in the spec.

    • Improve ALSA device names from ACP.

    • Fix various crasher bugs. One in the pulse layer, one in the session manager.

    • Make alsa plugin respect the PIPEWIRE_REMOTE env variable.

    • Various compile fixes.

  • 0.3.8   0.3.8 release

    Release 0.3.8

    PipeWire 0.3.8

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

    • Fix an embarrassing crasher in the JACK layer when metadata keys were removed.

    • Make it possible to add properties to jack clients with a PIPEWIRE_PROPS env variable. This can be used to make JACK nodes look like a device (like an effects rack).

    • Improvements in the session manager in how it links ports. Now it will try to link matching channels first and be more intelligent otherwise. The session manager will also configure the stream to the device port configuration when needed.

    • Add ofono backend for Bluetooth HeadSet support.

    • Improve default source and sink handling. They are now stored with their id, instead of name, in the metadata. This makes it work better with JACK because of JACK's limited name length.

    • Improve environment variables to make it possible to create and connect to servers other than "pipewire-0". Implement this in pulseaudio, JACK and alsa layers.

    • Add an alsa mixer plugin so that alsamixer works with PipeWire. It will configure the default source/sink volumes.

    • Fix capture devices. There was something wrong with how the resampler was used that caused corruption in the signal when the resampler was active.

    • We now ship alsa card paths, profile-sets configuration files and udev rules so that we don't have to rely on the pulseaudio ones.

    • Many build and stability fixes.

  • 0.3.7
    0b3e9eda · 0.3.7 ·
    Release 0.3.7

    PipeWire 0.3.7

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

    • Improved PulseAudio compatibility. The alsa card profile code was reused from PulseAudio. Devices now support all profiles, ports, jack detection, UCM and hardware mixers that PulseAudio implements. There should not be (almost) any difference between PipeWire and PulseAudio in how it presents and manages devices. Other missing API pieces such as the default sink/source and move_stream are implemented now. At this point it should be possible to replace PulseAudio with the compatibility layer for those who want to try.

    • Many fixes and improvements to the GStreamer elements. pipewiresrc now has the ability to periodically resend the last frame. This makes it possible for use-cases like screensharing to only update the screen on changes while still keeping the client side encoder busy. PipeWire elements can now also share a connection between them.

    • Improvements to the bluetooth nodes. Dynamically adding and removing devices should work much smoother now. Many fixes and improvements to a2dp and sco nodes.

    • Reduced memory usage by using less pre-allocated memory where possible. JACK clients are especially using less memory.

    • Support for passive links is added again. These are links that don't cause the associated driver to become active. This makes it possible to have blocks of effects+sinks go to suspend as a group when not in use.

    • Both consumers and producers can now ask to renegotiate the format. This required some cleanups and improvements to how links and node states were handled. More work is needed to implement more use cases.

    • Important fixes to how memory is shared with clients. Memory was not correctly freed in all cases, which would result in reuse of the wrong memory.

    • Support for planar formats for audio and video was added.

    • Improved error handling in the session manager.

    • Metadata is now used to manage default audio source and sink devices. The session manager will try to link streams to the default device. Changing the default device will move streams to the new device. PulseAudio and JACK layers respect the default source/sinks.

    • Metadata is used to tag the desired output device for a stream and the session manager will move streams when the metadata changes. The PulseAudio layer uses this to implement the move_stream feature.

    • Many fixes to the security modules. The session manager now has a flatpak module that grants permissions to flatpak apps. The PulseAudio layer now respects the permissions of objects. Security related properties are made read-only now. Different access modules can now coexist.

    • The portal module has been split up in 2 parts:

      1. a part living in the daemon that monitors the portal dbus owner and tags all clients from this PID. This part has to run in the daemon in order to securely tag the clients.
      2. a part in the session manager that uses the permission store to manage the permissions of portal managed clients.
