0.3.8 release

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.
