# PipeWire 0.3.83 (2023-10-19)

## Highlights

• A quantum change regression was fixed.
• Use a 2 socket server now for the manager and the applications with (when wireplumber is updated) different permissions.
• Reduce memory usage a little in audioconvert and use fewer buffers.
• Some JACK deadlocks were fixed.
• More bugfixes and improvements.

## PipeWire

• Fix quantum change regression.
• Use a 2 socket server by default. One for the session-manager and one for applications.
• Fix a potential use-after-free in node and device cleanup.

## modules

• Some hardcoded buffer size limits were removed.
• Fix ASYNC flag on combined-streams.
• Add support for on-demand combined-streams using metadata.

## SPA

• alsa-udev will now ignore PCMs with the ACP_IGNORE udev environment variable.
• The audioadapter now uses at least 2 buffers when the follower is async.
• The number of buffers used by plugins was tweaked a little. Most plugins now only ask 1 buffer.
• Memory usage in audioconvert was reduced.
• Fix some unaligned reads and writes and undefined left shifts reported by ASAN.
• Rework vulkan dependency checking.
• Don't try to link ALSA devices when prepare fails. This fixes some crashes.
• Fix a stall when the allowed codecs are changed in ALSA.
• Improve ALSA rate control for sources to avoid xruns.
• Try to fix IEC958 TrueHD and DTS playback.

## Bluetooth

• Improve fallback SCO mtu when the kernel doesn't tell us.

## JACK

• The fixed buffer size limit was removed.
• Add an option to make input buffers writable (default true).
• A potential deadlock was fixed when applications lock the process function.
• Use a separate thread to dispatch notifications to avoid deadlocks.
• Potentially fix silent export in ardour in some cases.
