Arctis Sound Manager has been released in version 1.4.20.

The update reverts the changes from version 1.4.19: the fixes for issues #223 and #230 had made filter-chain crashes more frequent on some hardware, not less. The fix for #223 pinned loopback playback nodes active via node.pause-on-idle=false, while the fix for #230 added cross-process locking around daemon and GUI link rewrites - together, these kept the audio chain continuously active, which triggered an underlying PipeWire concurrency bug more often. Reverting both restores the original idle-suspend behavior.

The release reverted fixes from version 1.4.19 that addressed issues #223 and #230. According to the notes, those previous changes “made filter-chain crashes more frequent on some hardware, not less.”

Key details:

• Issue #223’s fix had pinned node.pause-on-idle=false on loopback playback nodes
• Issue #230’s fix added cross-process locking around daemon and GUI link rewrites
• Together, these changes kept the audio chain continuously active, triggering an underlying PipeWire concurrency bug more frequently
• The removal of both fixes and associated safety measures restores the original idle-suspend behavior
• The maintainers acknowledged this reopens #223’s symptom (intermittent silence) but considered it preferable to crash loops
• Issue #230 remains open for a proper resolution
