For the frequency of this package's releases, they make a lot of changes. this is the 9th update this year.

# PipeWire 0.3.35 (2021-09-09)

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

## Highlights

  • S/PDIF passthrough over optical or HDMI is now implemented.
  • Some critical fixes to MIDI, draining of streams and various modules.
  • skypeforlinux should work better now after adding it to the quirks database.
  • Bluetooth codecs are now in separate plugins to make it easier to ship them.

## PipeWire

  • Drain was fixed in pw-stream. In some cases it would not clear the drain state correctly. Fixes the issue where speaker-test would only play one channel.
  • Loopback connections to a driver will now activate the driver. This fixes an issue where MIDI connections between devices or some applications (puredata) would not get any MIDI messages.
  • The audiomixer can now mix more formats. Together with the passthrough improvements this can be used to avoid conversions to/from the DSP format in some cases.
  • Make sure we idle drivers when removing a node from it in all cases. JACK clients could keep a driver node busy.
  • Add new methods to accumulate object info. The old one was difficult to use when applications need to accumulate multiple changes.
  • A new interface to load modules has been added. Plugins can use this to ask the host (PipeWire) to load spa plugins.
  • Increase param buffer size to handle larger params. Nodes with a large number of channels would sometimes not have properties.
  • Concurrent link negotiation that caused some links to not work, is now avoided. This fixes monitor ports in Ardour6.
  • Small tweaks to how the quantum and rate are handled when nodes move between drivers. Make node.lock-quantum work with node.latency

## PipeWire modules

  • The convolver plugin in filter-chain has been optimized some more.
  • The echo-cancel stream properties were improved so that it actually can remember the streams it links to.
  • module-pulse-tunnel had the buffer attributes wrong and would cause high latency with older pulseaudio servers.
  • module-roc had the properties configured wrongly, which would cause it to not work at all in most cases.
  • There is now an example of a 7.1 virtual surround sink using the hesuvi impulse responses.
  • The convolver now supports dirac pulses as the IR.

## ALSA

  • UCM config is now cached per device, using up less memory. It also temporarily works around a problem in alsa-lib that is now being patched and rolled out. Should stop devices from disappearing when logging out and back in.
  • Fix the MIDI clock rate matching. It was too sensitive to small changes and would spiral out of control and break MIDI rather quickly.

## pipewire-media-session

  • The media session can now save and restore IEC958 (S/PDIF) codecs for the sinks.
  • Passthrough of IEC958 (S/PDIF) content is now possible. If the client and the sink contain a compatible set of codecs, an exclusive connection can be made between client and sink to pass the encoded S/PDIF content directly to the device.
  • Use new introspection info update methods to suspend nodes in all cases. Sometimes, nodes would fail to suspend because the state info was not evaluated.
  • The media session can now work in non-DSP mode, which will try to avoid any audio conversions between client and device when possible. But, this will also disable compatibility with JACK applications.

## Bluetooth

  • Bluetooth codecs are now compiled into sperate plugins which are dynamically loaded. This makes it possible to change the plugin implementation or ship plugins separately without having to recompile the bluetooth module.

## PulseAudio server

  • Delay stream create reply until the stream is linked to a sink/source.
  • The device-restore extension is now implemented. This makes it possible to configure the IEC958 (S/PDIF) codecs supported by the sink with pavucontrol.
  • skypeforlinux now uses the same quirks as teams to make the sinks show up in all cases. This fixes the issue of not being able to hear the remote end in skypeforlinux.

## JACK

  • Improve catia and carla compatibility by caching objects a little longer after being removed.
  • JACK ports now notify the negotiated format correctly.
  • A potential deadlock was fixed when multiple threads would perform a call that would require a roundtrip.
  • Improve bufsize callback, it should not be called right after doing activate() but only when the buffersize changes later.
  • Add tweak to disable the process lock. Some older apps might not expect it.

## Docs

  • man pages are now generated with rst2man.
  • DMA-BUF docs were updated.
  • Documentation updates.
