# PipeWire 0.3.72 (2023-06-26)

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

## Highlights

• Fix a critical bug that would refuse to update the samplerate or buffersize in JACK clients.
• A new module-netjack2-driver and module-netjack2-manager were added that are compatible with NETJACK2. This allows PipeWire to become a NETJACK2 manager or a driver between JACK2 or PipeWire servers.
• Support was added for firewire devices with FFADO. This is untested for now and MIDI is not implemented yet.
• The node scheduling was optimized some more. External drivers are now as efficient as in-server ones. This should improve performance of various drivers such as bluetooth and JACK based drivers.
• Many, many bug fixes and a ton of improvements.

## PipeWire

• pw-filter can now be used to write sinks and sources.
• The node activation for drivers was changed. The driver now does not need to go to the server to start the processing cycle. This makes out-of-server drivers as efficient as in-server drivers.
• Don't try to use drivers with 0 priority as fallback drivers. This avoids making the screencast driver a driver for audio.
• Improve xrun count reporting in pw-top and the profiler. Now each node has their own xrun counter updated when it fails to complete processing during the cycle.
• pw-filter now also has support for TRIGGER.
• A potential fd leak was found when fds were send to a zombie client.
• Fix a bug where monitor or capture streams were logged twice in the profiler.
• Remove stream hooks safely.
• A bug in serialization of container properties was fixed. This could result in truncated property values.
• The PIPEWIRE_AUTOCONNECT environment variable now always overrides the autoconnect settings of streams.
• Node, port and link destroy now avoids some useless work.
• Port will now try to renegotiate a new format when idle.

## Modules

• The module-sap now is more compatible with AES67.
• A new FFADO driver module was added. This is completely untested because of lack of hardware. Please test and report issues.
• A new NETJACK2 driver and a NETJACK2 manager module were added. These should be drop in replacements for the JACK2 parts.
• The RAOP discover module now tries harder to only list devices once.
• The zeroconf discover module now tries harder to only list devices once.
• The RAOP sink module now handles latency better and is compatible with some more devices.
• The loopback and filter-chain modules now always dequeue the last input buffer to avoid stuttering in some cases.
• The SPA node factory module can now also export nodes. This is used to export the PTP clock from the AES67 config file.
• A bug in module-jack-tunnel was fixed that would cause stuttering and corrupted output in some cases.
• The resampler is now disabled in module-loopback and filter-chain when the samplerate is set to follow the graph rate.
• The way the mixer peer is sent to clients was improved. It is now also possible to let a remote node know about mixer port removes, which can avoid memory leaks and some code simplifications.

## SPA

• Monitor ports now report latency correctly.
• The ALSA plugin now uses htimestamp to get a more accurate ringbuffer position to estimate the clock skew.
• The channelmixer now has min/max-volume settings to limit or fix the volume.
• The ALSA plugin can now control the playback and capture rate of USB gadgets. This can avoid resampling and instead use the USB feedback to control the rate.
• The ALSA output to multiple devices has been improved, some lockups are avoided when the device ringbuffer is full.
• The compress-offload sink has improved negotiation.

## pulse-server

• Only try to use GSettings when the schema exists.
• @DEFAULT_SOURCE@, @DEFAULT_SINK@ and @DEFAULT_MONITOR@ are now correctly handled as targets in playback and capture streams.
• 2 new quirks are added to disable volume updates on sinks/sources.
• The virtual-sink and virtual-source modules were added. These are really example modules but actually also work and are useful on PulseAudio so implement them as well.
• Fix initial stream volumes.

## Bluetooth

• Only register A2DP or BAP when we have codecs.
• Include codec into the media.name

## JACK

• Fix a critical bug that would refuse to update the samplerate or buffersize.
• Improve updates of samplerate/buffersize, delay the updates until the client is activated.
• Use the new mix-info updates to simplify the mixer setup and peer detection.

## GStreamer

• Fill default strides instead of 0 on pipewire video buffers.
