PipeWire 1.4.9 Improves ALSA Recovery and Adapts to Newer libcamera Changes
PipeWire 1.4.9 is a small bugfix release that addresses a regression in node unprepared, which would leave nodes running, improves ALSA recovery when “3 periods” is not supported, and removes RestrictNamespaces from the systemd files to allow libcamera to load sandboxed IPA modules.
This release also fixes the initial SDP session hash and session-id, fixes a potential NULL deref in the profiler, fixes the UMP event compare function, and fixes a regression in the adapter that would cause it to fail to start and resume correctly.

PipeWire 1.4.9 Fixes Audio Regression and Improves ALSA Recovery
PipeWire, a multimedia framework for handling audio and video on Linux systems, has just rolled out version 1.4.9, focusing on bug fixes and stability improvements.
The release fixes a regression in node unprepare that could leave nodes running and trigger errors. ALSA handling is improved—PipeWire now recovers correctly when three periods aren’t supported and adjusts SOF card headroom to the minimal period size by default.
Another change removes the RestrictNamespaces directive from systemd service files. This allows libcamera to load sandboxed IPA modules again, restoring functionality that was previously blocked.
